As far as I can tell, this isn't used anywhere anymore

This allows us to use a more recent version and to drop the dependency
of glib (and python) which allows a better bootstrap on limited systems

The code is Linux-specific anyway.

Even Ubuntu 8.04 LTS is more recent.

For mingw.org, we ship a single dxva2api.h which contains stuff
normally present in dxva.h, so skip dxva.h.

Initially, I made it a header file suitable for conditional inclusion.

However slim read/write locks in Windows Vista do not support
asynchronous procedure calls, so they cannot be leveraged in VLC.
Thus rwlock.c needs to be included forever on Windows. (The same
limitation prevent usage of condition variables also in Vista+.)

Ref #7431 #5377

Also reorder Win32 functions to avoid forward declarations.

This avoids having to make assumptions about the layout of the
underlying condition variables in the OS.

nacl doesn't use pic as does mingw.

Using the foreign flavour you can forego the ABOUT-NLS file as well as
keep the custom INSTALL file.
