Add one copy of the function into each of the libraries, similarly
to what we do for log2_tab. When using static libs, only one
copy of the file_open.o object file gets included, while when
using shared libraries, each of them get a copy of its own.

This fixes DLL builds with a statically linked C runtime, where
each DLL effectively has got its own instance of the C runtime,
where file descriptors can't be shared across runtimes.

On systems not using msvcrt, the function is not duplicated.

This is necessary after the old av_gettime in libavformat was
dropped.

This will allow us to avoid copying the packets in many cases.

This breaks ABI.

Upstream decided to split the paranoia interface and move the headers
accordingly.

Codec timebase is supposed to be set by decoders only.

v4l2_read_header() does no cleanup, so it can return directly, without
any need for goto.

The function find_things() in configure is confused by component
registration calls as part of multiline macros defining combined
component registration.  Coalesce those macros into one line to
work around the issue.

Also reorder some other #include when applicable.

DV1394_NTSC has a lower value than DV1394_PAL.

We generally do not declare variables within for statements and
there are compilers that choke on such constructs.

Fixes Bugzilla #279.

Also remove one pointless zero initialization in rangecoder.c.

When using "-f x11grab -i :0.0" valgrind reports a definitely lost
memory block with this message:

==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2

The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's
free param in the exit path.

Also check the av_strdup() return value.

Note: calling av_free(param) even when av_strdup() fails and param is
NULL is OK and keeps the code simpler without adding another label to
skip av_free().
