Use AVERROR_EXIT with url_interrupt_cb.

Functions interrupted by url_interrupt_cb should not be restarted.
Therefore using AVERROR was wrong, as it did not allow to distinguish
when the underlying system call was interrupted and actually needed to be...

In retry_transfer_wrapper, do not check url_interrupt_cb, causes problems
when writing and pressing q during encoding. Instead, check url_interrupt_cb
at the end.

Note that when a protocol is interrupted by url_interrupt_cb, some data may
be silently discarded: the protocol context is not suitable for anything...

URLProtocol: Add URL_PROTOCOL_FLAG_NESTED_SCHEME

If this flag is set, the protocol can handle URLs where the
scheme is a nested scheme such as applehttp+file: - the protocol
can handle any URL where the first segment of the nested scheme
belongs to this protocol....

Make register_protocol() use the function av_register_protocol2()

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).

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

Remove offset_t typedef and use int64_t directly instead.
The name offset_t is easily confused with the standard off_t type and

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.

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....

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.
