It's actually kind of wild that these flags are enabled by default.
They produce an incredible amount of console output spam.
Let's remove them, especially since we've made other changes to this
CMakeLists.txt
On a few of our buildbot instances, we get warnings about the usage of
deprecated functions. We should correct these, especially if we're
delegating to system versions of the libraries if they're available.
However, in order to do that, we need to update our library variant from
2.1.1 so that the non-deprecated alternatives are actually available.
The latest version has tons of security fixes (which is expected for a
library such as mbedtls).
Updating also allows getting rid of a few deprecation warnings.
PolarSSL has been renamed to "mbed TLS" and version 2.0 dropped backwards
compatibility. This commit adds only the necessary files without any
modifications, so it doesn't compile yet.
