this allows more asynchronous decoding and display thus improving
video smoothness.
It also seems to improve absolute video decoding speed for some reason

This fixes compilation on some OSes

The presence of the .SECONDARY directive caused thing to not always
be correctly rebuilt. Mentioning the object files explicitly as
targets gives the desired result of make not deleting them without
unpleasant side-effects.

Force version.sh to run whenever the version might have changed,
regardless of what is being built. This is done by attaching the
dependencies to a dummy file (.version) which is included from the
makefile. As make will always attempt to rebuild any included files
before considering other rules, this ensures that the real version.h
is (re-)created before it is required by any source file.

This silly program always writes its output to the current directory.
Changing directory is better than moving the file afterwards.

I couldn't measure it to be slower for normal interframe videos.
For the worst case, high-bitrate intra-only videos, it can be 0.7% slower.

This triggers lAPrev (e_a[0]) on the first SBR frame to be -1. The spec is
somewhat ambiguous to what this value should be but this increases the accuracy
of al_sbr_e_44_1 and similar streams from 14 bits to 15 bits.

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.

instead of using the original host name, since the RTP (and UDP) protocols
may choose another IP address if the host name resolves into several different
addresses.
