Conio.h is a non-standard header and may not have kbhit()
prototyped. This fixes compile on OS/2 where the EMX version (we're
using a fork) of conio.h only has getch() and getche().

That fixes .lib creation for the win64 target.

Remove usage of tcgetattr and tcsetattr to modify terminal
parameters, and rely on ctrl-c to stop instead of pressing 'q'.
On systems with conio.h, keep the old behavior.

Changing the terminal settings causes problems if multiple instances
are running asynchronously on the same terminal, such as during a
parallel FATE run, or if the process crashes before restoring the
terminal.  In both cases, the terminal state is messed up requiring
a manual reset.

These windows do not really belong in fft/mdct files and were

This way building ffmpeg on mingw won't require windows specific tools

This avoids the main/SDL_main declaration clash caused by SDL on
Windows and other platforms.

Since initially committed in 2004, this codec has only been touched
for maintenanance.  Functionally, it contains no novel ideas and
its intended audience is better served by existing mature codecs.

This makes existing pkg-config uses as well as the libsdl checks
use the new pkg-config helper functions, which should be more
robust against broken systems.
Signed-off-by: NMans Rullgard <mans@mansr.com>

This adds helper functions for checking packages with pkg-config
and managing the associated flags.

Note that pkg-config use is still discouraged due to widespread
poor practices resulting in broken flags in many situations.  A
few badly designed packages require flags only obtainable using
pkg-config, and these functions are intended for those cases.

This makes it possible to pass a space-separated list of functions
to check_func_headers and check_lib2.  If any function is missing,
none are enabled as available, so this should only be used for
all-or-nothing sets, i.e. groups in which none will be used if any
one is missing.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
