The speex library has been split into a codec part
(speex) and a dsp part (speex-dsp). As we still need
the codec for compatibility with 3rd party clients
only sending speex but still want the updates that
went into the dsp and codec since then this patch
modifies our build to enable that. To achieve that
we combined the two libraries back together. Doing
it this way might brittle but is only a temporary
solution until we can actually drop the codec part.
Prior versions of mach_override were small (a single file),
and we just had its source live in the OS X overlay directory.
Newer versions of mach_override use libudis86, so the file count
goes up a fair bit. So much so that it doesn't make sense to
have it live inside the OS X overlay anymore.
Because of that, this commit moves it into 3rdparty.
This commit adds MinHook as a 3rd party
dependency and adds an alternative HardHook
implementation that makes use of MinHook.
This new MinHook-based HardHook implementation
allows us to provide an overlay for Mumble on
Windows x64.
The x64 overlay hasn't seen much testing in
real-world x64 games, except some minor testing
for World of Warcraft running in x64 mode, where
it works just fine.
There seems to be a compatibility with the Uplay
overlay, which causes Far Cry 4 to crash at the
"Press any key to continue" screen that is shown
just after launching the game. However,
Assassin's Creed: Unity works fine, so it might
just be a Far Cry 4 issue.
The x64 overlay also seems to interoperate with
the Steam overlay just fine.
I think this is a good starting point for the
feature. Let us get it into snapshots and let
us try to squash any addition bugs we find.
