Edênis Freindorfer Azevedo 5848feaea2 Fix video/audio recording.
We create a namespace to deal with most of our recording solution.

Besides that, we also add some functions to remove the need of
including libavutil headers on other part of the code. This is meant to
isolate most of recording solution components on the proper files.

We will start with a limited number of codecs supported; slowly we
should add them as they are tested (the previous one did not work for
most codecs listed).

This should support `ffmpeg 4.1` and further, including removing
all compilation warnings related to versions discrepancy.

Edênis Freindorfer Azevedo 060da968eb [LINUX] Add option to disable the online updater.
Add option to remove all configuration related to checking for updates
online. Although it is not implemented at the moment, these options
appeared on our menu `Options` > `General ...`.

- Fix need of patch on #140.

update Visual Studio support
Replace the vcpkg code with a newer and better version. In this version
the `vcpkg` directory is on the same level as the source directory, so
that IntelliSense does not get confused scanning for files.

The cmake variable `VCPKG_TARGET_TRIPLET` is required to activate vcpkg
support, it must be set to e.g. `x64-windows` or `x86-windows`.

Update `CMakeSettings.json` for the new code for the GUI.

Fix a problem copying the `SDL2.dll` file to the binary directory.

Update `README.md` with commandline instructions.

support FreeBSD
Make some changes to support out-of-the-box builds on FreeBSD:

- set cmake OpenGL type to `LEGACY`, the new `GLVND` type produces
  unusable binaries on FreeBSD

- on FreeBSD add -I/usr/local/include to compiler flags, why this is
  necessary I don't know

- look for llvm tools such as `llvm-ar` in `/usr/local/llvm-devel/bin`,
  LTO works

- improve the `find_wx_util()` cmake function to handle `wx-config`
  scripts named in the form e.g. `wxgtk3u-3.1-config`

- add FreeBSD support to `installdeps`

- make some minor changes to included headers based on macros such as
  `__FreeBSD__` to compile on FreeBSD, including adding a `BSD.h` header
  with some defines for e.g. `fseeko64`

- move the cmake X11 detection to before the wx compile tests, because
  otherwise the extra compile flags for the wx tests make the X11 tests
  fail

- make some minor changes to fix wx 2.8 compatibilty again, we don't
  actually use 2.8 for FreeBSD but I was testing it

wx 2.8 compat fixes, centos support, cmake fixes
Add support for RHEL/centos to installdeps. There is no SFML package.

Add some string compatibility stuff so that everything builds on wx 2.8
unicode builds.

TODO: add travis slaves for 2.8, with and without unicode

Disable the game frame spacer code on 2.8 because it does not work (the
frame does not expand.)

cmake improvements:

- set ENABLE_LTO=OFF for Debug builds by default

- set ENABLE_LINK=OFF if SFML cannot be found and continue

- use better logic for finding wx utilities wx-config and wxrc

cmake: gcc/clang colors with ninja, fix warnings
Ninja requires `-fdiagnostics-color=always` instead of
`-fdiagnostics-color=auto` with gcc because it pipes output from the
compiler unlike regular makes.

Use `-fcolor-diagnostics` for clang, which also works correctly with
ninja to show colors.

auto deps for visual studio, take 1
Use vcpkg to build deps when Visual Studio on Windows is detected, this
only happens on first build, but does take a while because things like
wxWidgets need to be built. Building from the developer command line is
also supported.

I considered making a pre-built tarball available, but the resulting
files are just too big for this to be practical.

Make the necessary cmake code changes for this to work and to use the
vcpkg packages, which work just like on linux or have other cmake glue
code available.

To do this, we make vcpkg a submodule, use git to checkout all
submodules, then just build and use the `vcpkg.exe`. Then we set the
CMAKE_TOOLCHAIN_FILE to the vcpkg toolchain and also include it
directly, why this is necessary I don't know, without it it doesn't work
in the IDE but does on the command line.

All of this requires no vcpkg integration with either the user or the
project. A user-wide `ENV{VCPKG_ROOT}` is also supported.

Fix the dynamic arrays in the GBA core, MSVC follows the C++ standard on
this and gcc does not.

TODO: add the necessary gcc flags to make this an error in cmake.

Use `wxArrayString` instead of `std::vector<wxString>` in
`src/wx/strutils.cpp` which is used in options parsing. This was
necessary because of a bizarre linker error with wxWidgets when using
Visual Studio:

https://trac.wxwidgets.org/ticket/10884#comment:46

In `src/wx/panel.cpp` make sure the unimplemented D3D renderer code does
not get compiled if it's actually `OFF`.

Also fix the new spacer code for the drawing panel to not combine
`wxEXPAND` with `wxALIGN_CENTER`, which is an error on wxWidgets 3.1.2,
which is what vcpkg uses. The drawing panel seems to be automatically
stretched to the max size automatically anyway.

TODO: if all of this works, we'll need an Appveyor set up for visual
studio.

Make mac builder use -m32 in CFLAGS etc. to produce a 32 bit binary
targetting 10.7 (Lion.) This provides the greatest backward
compatibility for older macs, and also allows for asm filters.

Fix an issue with m4 on 10.13 using a patch from macports.

Support `-pX` patch level args in DIST_PATCHES in builder.

Fix an issue with bison on 10.13 by bumping the version to 3.0.5.

Build libxslt `--without-crypto` so that it doesn't try to link the brew
libgcrypt.

Invoke cmake for dists with -DCMAKE_C_COMPILER_LAUNCHER=ccache and
-DCMAKE_CXX_COMPILER_LAUNCHER=ccache to use ccache, and set
CMAKE_C_COMPILER and CMAKE_CXX_COMPILER to the actual compilers not
prefixed by ccache.

When checking for ccache in vbam cmake code, check that
CMAKE_CXX_COMPILER_LAUNCHER and CMAKE_C_COMPILER_LAUNCHER were not
already defined (generally on the command line.)

Remove align attributes from sections in 2xSaImmx.asm, macho format on
mac does not support this and the filter works fine without them.

In the Quartz2D renderer, pass the NSRect view.bounds through
NSRectToCGRect when calling CGContextDrawImage(), this is necessary for
the 32 bit API.

Bump openssl to 1.0.2o.

Bump libxml2 to 2.9.8.

Update URL for urw fonts, and improve the dist downloading/unpacking
code to handle URLs that do not contain the filename (for .tar.gz and
.zip as identified by `file`.)

Change post-build for harfbuzz from `rebuild_dist freetype;` to
`rebuild_dist freetype --with-harfbuzz=yes;` as it was supposed to have
been.

Build cmake itself with --parallel and --enable-ccache.

Silence errors from killed jobs due to tmp directory being gone.

Write a couple of string functions, rtrim() and gsub().

Make path_exists() handle globs with spaces in them, by escaping the
space.

Use --host and --build args to autoconf configure to "cross-compile" for
32 bits, this is necessary for some dists, and does not work for others,
remove it for dists where it does not work.

Add COMMAND_MODE=unix2003 to the build environment, this is necessary to
fix some build errors, why I have no clue, found it on stackoverflow.

Pass -Wl,-no_compact_unwind in LDFLAGS to openssl, this is necessary for
32 bits.

Force sfml to compile as 32 bit, it normally does not allow this.

Remove shared-mime-info from this build, it's not necessary for anything
and there are issues XML::Parser linked to our expat and brew perl that
need to be resolved.

hopefully become a separate repo on github at some point.

Add perl dist support to the builder.

Add an `--env` flag to the builder to print the build environment
variables so that they can be read in with `eval` for debugging
purposes.

To get the version, find the last tag in git tag of the form "v2.0.0" or
"2.0.0". If this is the last tag and the current commit matches the ref
of this tag, the revision will be empty.

In the case that the current commit is not tagged with a version, to get
the revision, use the short sha unless the current commit is tagged with
something that is not a version string, e.g.  "feature-foo", in which
case the revision will be "feature-foo".

If the current commit is tagged as e.g. "v2.0.1-foo" or "2.0.1-foo" then
the version will be "2.0.1" and the revision will be "foo". Tags of this
form are also checked when finding the current version.

This is all done in cmake. If there is no git detected, the version will
be "2.0.0" and the revision will be "unknown".

gcc lto wrapper commands such as `gcc-ar` will segfault with some

wrappers in a little executable that prepends their dirname to PATH and
runs them with `execvp()`.

Make LTO default to ON again, except on win32 with gcc < 7, because
those toolchains produce broken binaries with LTO enabled.

Also add `-ffat-lto-objects` to compiler flags for gcc when LTO is
enabled, this will increase the chances that the LTO build will succeed
even if there are issues with the binutils wrappers. Clang does not

Continue to use the GetGitRevisionDescription plugin to make the cmake
configuration state depend on the current sha of HEAD, but throw away
the results (for the time being.)

What this does is have cmake escape -D preprocessor definitions passed
to e.g. add_definitions() starting in cmake 2.6 . This is fine since the
minimum cmake version we support is 2.8.12 . It also makes the code
cleaner since we don't have to escape quotes anymore ourselves. This
will also work better on different platforms, where different escapes
may be needed.

Rafael Kitover 6af5525ac1 cmake: default to ENABLE_ASM_CORE=OFF #98 #54
The inline assembly in src/gba/GBA-thumb.cpp which is turned on with the
cmake ENABLE_ASM_CORES option, sometimes causes weird behavior on
windows (see: #54) and a crash on startup in linux (see: #98, confirmed
on both Fedora and Arch Linux.)

Previously the default for this option was ON for 32 bit builds, set the
default to OFF always for the time being, until it is either fixed or
replaced.

Rafael Kitover 2e8bee117d cmake: use add_compile_options for ssp-buffer-size
In 82c8a1e3 I made "--param ssp-buffer-size=4" one argument instead of
two because when added to CMAKE_REQUIRED_LIBRARIES the ssp-buffer-size=4
part was being recognized as a library, breaking the compile tests.

This broke the build on mac, which I fixed in 915e2d1e by using ssp
flags for gcc only and not clang.

Now apparently it is breaking mxe, so instead of adding this particular
parameter to the MY_C_FLAGS variable which is then added to
CMAKE_REQUIRED_* variables for compile tests, add it directly via
ADD_COMPILE_OPTIONS().

This should hopefully resolve any remaining issues with this compiler
flag.
