In -std=c99 mode GCC defines __STRICT_ANSI__ to hide non-ANSI interfaces.
This causes declarations for some POSIX functions to be omitted from system
headers, which causes compilation failures.
Older nasm versions have trouble assembling certain AVX instructions, but the
current AVX check did not detect this. Update the check to use an instruction
that triggers the nasm problem.
This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

046f081b46 reorganized the CPPFLAGS to no
longer add -D_POSIX_C_SOURCE unconditionally, but only on systems (e.g.,
glibc based ones) that require it. As kFreeBSD uses glibc, it needs to
be treated similar.
Additionally, _BSD_SOURCE is turned on to enable some additional types
such as caddr_t, which are normally enabled on BSD but not with glibc.
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.

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 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.

Recent gcc versions define __ARM_PCS or __ARM_PCS_VFP to indicate the
VFP ABI in use, and ARM RVCT defines __SOFTFP__ when using this ABI.
If none of these are defined, check $cross_prefix and $cc for the
substring "hardfloat", and finally fall back to a linker test. This
gives the correct result in most configurations.
Some linkers fail if this flag is used when creating an executable file.
Since the flag is meaningful only for shared libraries, dropping it from
the main link flags is correct.
