aac: Simplify decode_mid_side_stereo

Might spare few cycles if the compiler is naive and
makes the function more readable.
rtsp: move the CONFIG_ macros to the beginning of the check

With --disable-optimizations, the DCE of some compilers does not remove
such unused code, causing linking failure.
mov: do not truncate the language-prefixed tag
mov: Add an option for exporting all metadata
mov: allocate the tag value dynamically

This allows to load metadata entries longer than 1024 bytes.
Displaying them is still limited to 1024 characters, but applications
can load them fully now.

options_table: fix colorspace minimum option value

The min value for colorspace should be zero and not one since the first
valid index into the frame colorspace array is AVCOL_SPC_RGB which is 0.

configure: add optional pkg-config helper and use it.

The require variant dies if the package is not present.
The check variant does not import the flags to the used list.
The new variant imports the flags if the package is present
but does not die if it is not.
The new call graph is: require -> use -> check.

Use use_pkg_config for libx264 and libsmbclient: more readable
and three external call less per library.
configure: add a note about pkg-config --static.

Try to detect "$cc -static" without "pkg-config --static".
Also, when a library detection using pkg-config fails,
make it explicit this was pkg-config.
Revert "avfilter/vf_interlace: more accurate pts calculation"

This reverts commit df8248f66e362c3015d95ac86d1917dde8dc0a0c.

the revert produces a timebase and timestamps that are more close
to what users expect
