16c3ed5837 libavutil: cast truncated values to uint32_t
programs using ffmpeg that are compiled with -Wshorten-64-to-32
gives a warning when using header files common.h and rational.h

cast 64-bit truncated values to (uint32_t) to avoid the warning

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.

987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
