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.

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.

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.

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.

Passing an explicit filename to this command is only necessary if the

This allows applications/libraries which require that symbol
(e.g. libavfilter) to be compiled without to depend on the presence of
libavcodec/avcodec.h, which may not be installed.

Error code definitions and handling code belong to libavutil, where
they can be shared by all the libav* libraries.

This reduces the number of false dependencies on header files and
speeds up compilation.
Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk
ffmpeg.c uses lrintf(), which is missing on some systems. Previously
it picked up the replacement via libavutil/internal.h due to
HAVE_AV_CONFIG_H being erroneously defined.
Moving these replacements to a separate header enables ffmpeg.c to
use them without being exposed to internal interfaces.
This use of a non-public header is justified by the header in question
not being part of the internal interface either. It should rather be
considered as part of the build system, which is shared between the
libraries and the applications.
This header cannot be installed since the tested conditions depend on
the compiler.
