9d30e0682a Do not initialize res in url_fseek(), in the case !s->seek directly 
return AVERROR(EPIPE) rather than the pre-defined value of res.

Slightly improve readability.

7f7686dfb1 Make get_buffer and get_partial_buffer return url_ferror or AVERROR_EOF as 
appropriate if it couldn't read any data at all.
This should make handling of EOF and error simpler or make it work right without
extra code in a few place (e.g. raw demuxer).

bc5c918ea8 Remove offset_t typedef and use int64_t directly instead.

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

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.
