Update external polarssl to 1.3.8 

There were some fixes back on March 13th, 2014 for fixing compiling on MIPS64.
Also some fixes on June 25th, 2014 for SPARC64 fixes.

Probably more things, but those are what I care about.

PolarSSL ChangeLog (Sorted per branch, date)
= PolarSSL 1.3.8 released 2014-07-11
Security
* Fix length checking for AEAD ciphersuites (found by Codenomicon).
It was possible to crash the server (and client) using crafted messages
when a GCM suite was chosen.
Features
* Add CCM module and cipher mode to Cipher Layer
* Support for CCM and CCM_8 ciphersuites
* Support for parsing and verifying RSASSA-PSS signatures in the X.509
modules (certificates, CRLs and CSRs).
* Blowfish in the cipher layer now supports variable length keys.
* Add example config.h for PSK with CCM, optimized for low RAM usage.
* Optimize for RAM usage in example config.h for NSA Suite B profile.
* Add POLARSSL_REMOVE_ARC4_CIPHERSUITES to allow removing RC4 ciphersuites
from the default list (inactive by default).
* Add server-side enforcement of sent renegotiation requests
(ssl_set_renegotiation_enforced())
* Add SSL_CIPHERSUITES config.h flag to allow specifying a list of
ciphersuites to use and save some memory if the list is small.
Changes
* Add LINK_WITH_PTHREAD option in CMake for explicit linking that is
required on some platforms (e.g. OpenBSD)
* Migrate zeroizing of data to polarssl_zeroize() instead of memset()
against unwanted compiler optimizations
* md_list() now returns hashes strongest first
* Selection of hash for signing ServerKeyExchange in TLS 1.2 now picks
strongest offered by client.
* All public contexts have _init() and _free() functions now for simpler
usage pattern
Bugfix
* Fix in debug_print_msg()
* Enforce alignment in the buffer allocator even if buffer is not aligned
* Remove less-than-zero checks on unsigned numbers
* Stricter check on SSL ClientHello internal sizes compared to actual packet
size (found by TrustInSoft)
* Fix WSAStartup() return value check (found by Peter Vaskovic)
* Other minor issues (found by Peter Vaskovic)
* Fix symlink command for cross compiling with CMake (found by Andre
Heinecke)
* Fix DER output of gen_key app (found by Gergely Budai)
* Very small records were incorrectly rejected when truncated HMAC was in
use with some ciphersuites and versions (RC4 in all versions, CBC with
versions < TLS 1.1).
* Very large records using more than 224 bytes of padding were incorrectly
rejected with CBC-based ciphersuites and TLS >= 1.1
* Very large records using less padding could cause a buffer overread of up
to 32 bytes with CBC-based ciphersuites and TLS >= 1.1
* Restore ability to use a v1 cert as a CA if trusted locally. (This had
been removed in 1.3.6.)
* Restore ability to locally trust a self-signed cert that is not a proper
CA for use as an end entity certificate. (This had been removed in
1.3.6.)
* Fix preprocessor checks for bn_mul PPC asm (found by Barry K. Nathan).
* Use \n\t rather than semicolons for bn_mul asm, since some assemblers
interpret semicolons as comment delimiters (found by Barry K. Nathan).
* Fix off-by-one error in parsing Supported Point Format extension that
caused some handshakes to fail.
* Fix possible miscomputation of the premaster secret with DHE-PSK key
exchange that caused some handshakes to fail with other implementations.
(Failure rate <= 1/255 with common DHM moduli.)
* Disable broken Sparc64 bn_mul assembly (found by Florian Obser).
* Fix base64_decode() to return and check length correctly (in case of
tight buffers)
* Fix mpi_write_string() to write "00" as hex output for empty MPI (found
by Hui Dong)
= PolarSSL 1.3.7 released on 2014-05-02
Features
* debug_set_log_mode() added to determine raw or full logging
* debug_set_threshold() added to ignore messages over threshold level
* version_check_feature() added to check for compile-time options at
run-time
Changes
* POLARSSL_CONFIG_OPTIONS has been removed. All values are individually
checked and filled in the relevant module headers
* Debug module only outputs full lines instead of parts
* Better support for the different Attribute Types from IETF PKIX (RFC 5280)
* AES-NI now compiles with "old" assemblers too
* Ciphersuites based on RC4 now have the lowest priority by default
Bugfix
* Only iterate over actual certificates in ssl_write_certificate_request()
(found by Matthew Page)
* Typos in platform.c and pkcs11.c (found by Daniel Phillips and Steffan
Karger)
* cert_write app should use subject of issuer certificate as issuer of cert
* Fix false reject in padding check in ssl_decrypt_buf() for CBC
ciphersuites, for full SSL frames of data.
* Improve interoperability by not writing extension length in ClientHello /
ServerHello when no extensions are present (found by Matthew Page)
* rsa_check_pubkey() now allows an E up to N
* On OpenBSD, use arc4random_buf() instead of rand() to prevent warnings
* mpi_fill_random() was creating numbers larger than requested on
big-endian platform when size was not an integer number of limbs
* Fix dependencies issues in X.509 test suite.
* Some parts of ssl_tls.c were compiled even when the module was disabled.
* Fix detection of DragonflyBSD in net.c (found by Markus Pfeiffer)
* Fix detection of Clang on some Apple platforms with CMake
(found by Barry K. Nathan)
= PolarSSL 1.3.6 released on 2014-04-11
Features
* Support for the ALPN SSL extension
* Add option 'use_dev_random' to gen_key application
* Enable verification of the keyUsage extension for CA and leaf
certificates (POLARSSL_X509_CHECK_KEY_USAGE)
* Enable verification of the extendedKeyUsage extension
(POLARSSL_X509_CHECK_EXTENDED_KEY_USAGE)
Changes
* x509_crt_info() now prints information about parsed extensions as well
* pk_verify() now returns a specific error code when the signature is valid
but shorter than the supplied length.
* Use UTC time to check certificate validity.
* Reject certificates with times not in UTC, per RFC 5280.
Security
* Avoid potential timing leak in ecdsa_sign() by blinding modular division.
(Found by Watson Ladd.)
* The notAfter date of some certificates was no longer checked since 1.3.5.
This affects certificates in the user-supplied chain except the top
certificate. If the user-supplied chain contains only one certificates,
it is not affected (ie, its notAfter date is properly checked).
* Prevent potential NULL pointer dereference in ssl_read_record() (found by
TrustInSoft)
Bugfix
* The length of various ClientKeyExchange messages was not properly checked.
* Some example server programs were not sending the close_notify alert.
* Potential memory leak in mpi_exp_mod() when error occurs during
calculation of RR.
* Fixed malloc/free default #define in platform.c (found by Gergely Budai).
* Fixed type which made POLARSSL_ENTROPY_FORCE_SHA256 uneffective (found by
Gergely Budai).
* Fix #include path in ecdsa.h which wasn't accepted by some compilers.
(found by Gergely Budai)
* Fix compile errors when POLARSSL_ERROR_STRERROR_BC is undefined (found by
Shuo Chen).
* oid_get_numeric_string() used to truncate the output without returning an
error if the output buffer was just 1 byte too small.
* dhm_parse_dhm() (hence dhm_parse_dhmfile()) did not set dhm->len.
* Calling pk_debug() on an RSA-alt key would segfault.
* pk_get_size() and pk_get_len() were off by a factor 8 for RSA-alt keys.
* Potential buffer overwrite in pem_write_buffer() because of low length
indication (found by Thijs Alkemade)
* EC curves constants, which should be only in ROM since 1.3.3, were also
stored in RAM due to missing 'const's (found by Gergely Budai).
= PolarSSL 1.3.5 released on 2014-03-26
Features
* HMAC-DRBG as a separate module
* Option to set the Curve preference order (disabled by default)
* Single Platform compatilibity layer (for memory / printf / fprintf)
* Ability to provide alternate timing implementation
* Ability to force the entropy module to use SHA-256 as its basis
(POLARSSL_ENTROPY_FORCE_SHA256)
* Testing script ssl-opt.sh added for testing 'live' ssl option
interoperability against OpenSSL and PolarSSL
* Support for reading EC keys that use SpecifiedECDomain in some cases.
* Entropy module now supports seed writing and reading
Changes
* Deprecated the Memory layer
* entropy_add_source(), entropy_update_manual() and entropy_gather()
now thread-safe if POLARSSL_THREADING_C defined
* Improvements to the CMake build system, contributed by Julian Ospald.
* Work around a bug of the version of Clang shipped by Apple with Mavericks
that prevented bignum.c from compiling. (Reported by Rafael Baptista.)
* Revamped the compat.sh interoperatibility script to include support for
testing against GnuTLS
* Deprecated ssl_set_own_cert_rsa() and ssl_set_own_cert_rsa_alt()
* Improvements to tests/Makefile, contributed by Oden Eriksson.
Security
* Forbid change of server certificate during renegotiation to prevent
"triple handshake" attack when authentication mode is 'optional' (the
attack was already impossible when authentication is required).
* Check notBefore timestamp of certificates and CRLs from the future.
* Forbid sequence number wrapping
* Fixed possible buffer overflow with overlong PSK
* Possible remotely-triggered out-of-bounds memory access fixed (found by
TrustInSoft)
Bugfix

statistics
* Fixed bug in RSA PKCS#1 v1.5 "reversed" operations
* Fixed testing with out-of-source builds using cmake
* Fixed version-major intolerance in server
* Fixed CMake symlinking on out-of-source builds
* Fixed dependency issues in test suite
* Programs rsa_sign_pss and rsa_verify_pss were not using PSS since 1.3.0
* Bignum's MIPS-32 assembly was used on MIPS-64, causing chaos. (Found by
Alex Wilson.)
* ssl_cache was creating entries when max_entries=0 if TIMING_C was enabled.
* m_sleep() was sleeping twice too long on most Unix platforms.
* Fixed bug with session tickets and non-blocking I/O in the unlikely case
send() would return an EAGAIN error when sending the ticket.
* ssl_cache was leaking memory when reusing a timed out entry containing a
client certificate.
* ssl_srv was leaking memory when client presented a timed out ticket
containing a client certificate
* ssl_init() was leaving a dirty pointer in ssl_context if malloc of
out_ctr failed
* ssl_handshake_init() was leaving dirty pointers in subcontexts if malloc
of one of them failed
* Fix typo in rsa_copy() that impacted PKCS#1 v2 contexts
* x509_get_current_time() uses localtime_r() to prevent thread issues
= PolarSSL 1.3.4 released on 2014-01-27
Features

Tests
=====
PolarSSL includes a elaborate test suite in *tests/* that initially requires Perl to generate the tests files (e.g. *test_suite_mpi.c*). These files are generates from a **function file** (e.g. *suites/test_suite_mpi.function*) and a **data file** (e.g. *suites/test_suite_mpi.data*). The **function file** contains the template for each test function. The **data file** contains the test cases, specified as parameters that should be pushed into a template function.

Configurations
==============
We provide some non-standard configurations focused on specific use cases in the configs/ directory. You can read more about those in configs/README.txt
Contributing
============
We graciously accept bugs and contributions from the community. There are some requirements we need to fulfil in order to be able to integrate contributions in the main code.
Simple bug fixes to existing code do not contain copyright themselves and we can integrate those without any issue. The same goes for trivial contributions.
For larger contributions, e.g. a new feature, the code possible falls under copyright law. We then need your consent to share in the ownership of the copyright. We have a form for that, which we will mail to you in case you submit a contribution or pull request that we deem this necessary for.
