Move libm replacements to new header libm.h
...
ffmpeg.c uses lrintf(), which is missing on some systems. Previously
it picked up the replacement via libavutil/internal.h due to
HAVE_AV_CONFIG_H being erroneously defined.
Moving these replacements to a separate header enables ffmpeg.c to
use them without being exposed to internal interfaces.
This use of a non-public header is justified by the header in question
not being part of the internal interface either. It should rather be
considered as part of the build system, which is shared between the
libraries and the applications.
This header cannot be installed since the tested conditions depend on
the compiler.

DECLARE_ALIGNED macro for TMS470 compiler
...
This compiler supports gcc-style alignment attributes for struct,
but not for global variables. For the latter, alignment can be
specified with a pragma, which does not work for struct members or
local variables. By using both pragma and attribute, one or the
other will always take effect.
Unfortunately, no means exists for aligning stack variables.

H264 DXVA2 implementation

It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.
To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h )
The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.

intreadwrite: ensure arch-specific versions are always used if defined

The per-arch headers can define any combination of B/L/N variants.
This ensures that whatever is defined in an arch header gets used
for all equivalents not defined there. E.g. on a little-endian
machine, AV_RN and AV_RL should give the same code.
