9275438a19 Clean up av_get_cpu_flag() 
Instead of defining functions in per-arch header files included
by the main cpu.c, define them normally and call them from the
generic one.

3fc548df28 Make ff_inverse stay with libavutil, and optional copy it to libavcodec. 
The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up
to now the table was defined only in libavcodec.

After this change, the main copy of ff_inverse is part of libavutil (just
like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made
available to libavcodec, to avoid the performance penalty of using an
external look up table.

Dynamic linking works, because the libraries are linked with -Bsymbolic, so
the local copy of the symbol has priority over the external; static linking
works because the table is on a standalone object file in both libraries,
so the linker is able to discard one of the two.

Tested on Linux/x86-64 and Mac OS X/x86-64.

b7fa5c5abb random_seed: allow to block on /dev/random 
If both /dev/random and /dev/urandom failed to return data, an
uninitialised value might be returned.  Since most systems have a
non-blocking /dev/urandom or have /dev/random with similar properties,
the chance of blocking is minimal, and the alternative of returning
non-random data is worse.

a74d707cb7 av_alias is an attribute and belongs to attributes.h 
also attributes.h is public and external api and can thus not depend
on configure tested compiler support thus this part is removed. A
different solution must be found if this breaks for some compiler
which i hope it does not.

e2959f4558 Make av_strerror() return -1 even in the case when av_strerror_r() is 
not defined.

This allows applications to check if av_strerror() cannot provide a
meaningful representation for the provided error code, without having
to actually check the filled string.

441ea0ce91 Make av_strerror() print an error message mentioning the error code 
number if strerror_r() did not succeed for whatever reason.

This avoids the need for the application to fill the string in case
strerror_r() fails, for example because the error code is not known.

547b7bcbb7 bswap: add macros to byteswap constants 
The normal byteswap functions might use inline asm which is suboptimal
with constants (and cannot be used in static initialisers), so special
macros for constants only is needed.

We should not rely on the gcc __builtin_constant_p() test since it is
not always available.

cf103fabbe Drop AVERROR_NOTSUPP at the next major bump, use AVERROR(ENOSYS) 
instead which is semantically equivalent.
