This makes the RTMP writing code able to handle FLV data
fed in arbitrarily small or large chunks, with multiple
consecutive packets in one write call, or having the FLV
packet header split over numerous write calls.

When used in conjunction with the flv muxer, the AVIO buffer
size still needs to be large enough to fit the initial metadata
packet though, since the size of that packet is written with a
seekback.

If not enough bytes are available, keep track of them and skip
them on next call.

In practice, if these trailer bytes are written in a separate
call, there is no other data written in this call, making it
fall into the "FLV packet too small" case currently - working,
but not as intended.

This patch makes the code more robust, handling all cases
except for having the FLV packet header split over multiple
write calls.

If the FLV packet is larger than the AVIO buffer, a partial
FLV packet will be flushed to the RTMP protocol.

This commit handles the most common cases of FLV packets
being written in more than one call.

Original code had the assumption of only one FLV packet per RTMP packet. But that assumption is incorrect for higher bit rates. Made changes to the code to accommodate more than one FLV packet per RTMP
+packet.

Some received packets can have size 0. The return value from
av_malloc(0) may be NULL, which is ok if the size was 0. On
OS X, however, the returned pointer is non-null but leads to
crashes when trying to free it.

Make AVIO_FLAG_ access constants work as flags, and in particular fix
the behavior of functions (such as avio_check()) which expect them to
be flags rather than modes.

This breaks API.

This is more readable and makes it easier to reorder URLProtocol
members.

URLContext.max_packet_size should be used directly.

Now the first argument is URLContext *h. However, the function logs to
LOG_CONTEXT, which is #defined as 's' for new lavf major versions.

Therefore, rename h -> s.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

ff_url_split() is retained as an alias, as it was used by ffserver,
to avoid breaking ABI compatibility with it.

Earlier, the function only returned when the enough data to fill the
requested buffer was available. This lead to high latency when receiving
low-bandwidth streams.

This ensures proper escaping of numerical IPv6 addresses.

The RTSP (de)muxer needs its own network initialization, since it isn't
a protocol and url_open hasn't been called yet.
