a726d7fd4e AVOptions: in av_opt_find() don't return named constants unless unit is specified. 
That is, unless the caller explicitly asks for them.

Prevents conflict between e.g. the 'loop' option in img2 demuxer and
'loop' flag in AVCodecContext.

046f081b46 configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS. 
Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems
since it causes certain system functions to be hidden on some (BSD) systems.
The solution is to only add the flag on systems that really require it, i.e.
glibc-based ones.

This change makes BSD systems compile out-of-the-box without the need for
adding specific flags manually.  It also allows dropping a number of flags
set manually on a file-per-file basis, but were only present to work around
breakage introduced by the presence of _POSIX_C_SOURCE.

Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems.  We use XSI extensions
in several places already, so it is preferable to define it globally instead
of littering source files with individual #defines only needed for glibc.

bebe72f4a0 lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enums 
Also deprecate av_get_pict_type_char() in favor of
av_get_picture_type_char().

The new enum and av_get_picture_type_char() are defined in libavutil.
This allows the use in libavfilter without the need to link against
libavcodec.
