0a216bd1dd Make register_protocol() use the function av_register_protocol2()
rather than av_register_protocol(), which is deprecated.
Fix the GCC warning:
avio.c: In function ‘register_protocol’:
avio.c:93: warning: ‘av_register_protocol’ is deprecated (declared at avio.c:86)

2bab5d3e73 Allow all valid (and only valid) characters in URL scheme for url_open()
The URL specification allows letters, numbers, plus, hyphen, and period
in the scheme part.  The isalpha() test would allow additional characters
depending on locale settings while rejecting numbers and punctuation.

67d4b3f205 Always call ff_network_init/ff_network_close when opening protocols
ff_network_init is a no-op on all platforms except windows, and on
windows the performance penalty is minimal (less than 1 ms in my tests).

f0a8039464 Add url_get_file_handle(), which is used to get the file descriptor
associated with the I/O handle (e.g. the fd returned by open()). See
"[RFC] rtsp.c EOF support" thread.

There were previously some URI-specific implementations of the same idea,
e.g. rtp_get_file_handles() and udp_get_file_handle(). All of these are
deprecated by this patch and will be removed at the next major API bump.

*_t is POSIX reserved namespace if any POSIX header is included.

ba99cfc213 Implement url_open_protocol(), which is basiclly the former url_open()
but which opens a URLProtocol instead of a filename. url_open() is
reimplemented to call url_open_protocol(). See discussion on
"url_open_protocol" on ffmpeg-devel.

c306748c29 Move avio.h's url_get_max_packet_size() comment from source to header file.

8fa36ae09d This fixes error handling for BeOS, removing the need for some ifdefs.
AVERROR_ defines are moved to avcodec.h as they are needed in there as well. Feel free to move that to avutil/common.h.
Bumped up avcodec/format version numbers as though it's binary compatible we will want to rebuild apps as error values changed.
Please from now on use return AVERROR(EFOO) instead of the ugly return -EFOO in your code.
This also removes the need for berrno.h.

eabbae730c protect the size=seek(SEEK_END,-1)+1 results with an if (.. < 0), else the
return value may still end up being zero (if the seek returns -1, which is
e.g. what file.c will return on error), which is a valid (but incorrect)
filesize.
