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.
The low quality mode is off by default and never tested. The high
quality mode is also plenty fast enough.

Subject: [PATCH] Remove RDFT dependency from AAC decoder.

It was used for an old implementation of the SBR filterbank.
./configure --disable-everything --disable-ffplay --enable-decoder=aac works.
This restores the behaviour of running only the builtin
regression tests when no path to external samples is given.
aa3805a inadvertently broke this by always setting SAMPLES
to something. Using := makes the ifdef test work as expected
when the FATE_SAMPLES environment variable is empty.

Stripping is generally best left to package management tools, and
since unstripped copies are kept in the build tree, any arguments
about saving space (no matter how insignificant) are void.

When -std=c99 is used, GCC defines __STRICT_ANSI__ to hide non-ANSI
interfaces; on MinGW32, when this macro is defined, some functions that are
part of POSIX but not of Windows APIs are disabled, including strcasecmp().

This moves the check for --as-needed linker support before all
library tests, ensuring consistent behaviour between the checks
and the actual link step.

ICC lies about the version of gcc it emulates, which results
in unsupported attributes sometimes being used. The warning
is an annoyance and should be disabled.

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().

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.

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.

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.
