365e3c7878 Rename attribute_used to av_used and move it to attributes.h
This is consistent with most of the other attribute macros.

b462d13262 Add compatibility wrappers for functions moved from lavf to lavc
When symbol versioning is enabled, moving symbols from one library to
another breaks binary compatibility.  This adds wrappers with the old
version tag for the av_*packet functions recently moved to lavc.

a74d707cb7 av_alias is an attribute and belongs to attributes.h
also attributes.h is public and external api and can thus not depend
on configure tested compiler support thus this part is removed. A
different solution must be found if this breaks for some compiler
which i hope it does not.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

2ed6f39944 Replace many includes of libavutil/common.h with what is actually needed
This reduces the number of false dependencies on header files and
speeds up compilation.

335ee1aadd 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.
