currently libavformat only allows seeking if a request with "Range:
0-" results in a 206 reply from the HTTP server which includes a
Content-Range header. But according to RFC 2616, the server may also
reply with a normal 200 reply (which is more efficient for a request
for the whole file). In fact Apache HTTPD 2.2.20 has changed the
behaviour in this way and it looks like this change will be kept in
future versions. The fix for libavformat is easy: Also look at the
Accept-Ranges header.

Fixes bug 28.

Replace it with newly introduced libavutil API.

It allows to search for options only with AVClass, without allocating
the corresponding context.

1<<31 overflows because 1 is signed, so force it to unsigned.

also mentions the possibility to propose new types of issues to

It makes it also easier to spot the URLs which might be one of the main

This is the same code as for x86_64.
This is necessary because uname returns PPC64 if the hardware
is 64 bit, however the userland can still be fully 32 bit.
In that case FFmpeg fails to compile because some macros in the
asm code are set up incorrectly.

If st is NULL, it means no 'fmt ' tag is found, but 'data' tag (which
needs a previous 'fmt ' tag to be parsed correctly and st initialized)
check will make sure st is never dereferenced in that case.
