Tested and working with automake 1.11.1, builds and works fine. Confirmed by another project as well: https://github.com/mxe/mxe/issues/128

Also removed dist-lzip because of "configure.ac:29: option `dist-lzip' not recognized"

Use parenthesis around the expression returned in LIBAVUTIL_VERSION_CHECK,
to avoid problems that can arise in future with some ways macro may be used.

Same as what has been done in LIBAVCODEC_VERSION_CHECK.

If the input dies, the state changes and the Qt input manager will
delete the input anyway.

Note that checking b_eof and b_dead here is also wrong (no memory
synchronization), but that is left for later.

This was disabled by a2deb59a and does
not even compile anymore.

(Code is suspicious though.)

With older versions, client support pretty much does not work.

Make fails when using FFmpeg libavcodec version newer than checked by
LIBAVCODEC_VERSION_CHECK, because of redeclaration of many enumerators,
that are unnecessary with newer version of libavcodec library.
It is due to missing parenthesis in macro definition that are making
it wrong.

Probably same with libav libavcodec library, too.

Big pile of non-sensical and unmaintained code.
