There is no POSIX error code for EOF - recv() signals EOF by simply
returning 0. But libavformat recently changed its conventions and
requires an explicit AVERROR_EOF, or it might get into an endless retry
loop, consuming 100% CPU while doing nothing.

pts_wrap_bits defaults to 33 (like MPEG), that causes valid
timestamps to be unwrapped and become invalid.
Inspired by a patch by Wu Zhiqiang <mymoeyard@gmail.com>.

Encrypted HLS segments have regular http:// urls, but open_input()
actually prefixes them with crypto+ before calling open_url(), so
they end up using the crypto protocol and not the http protocol.

This means invoking ff_http_do_new_request will fail, so we avoid
calling it in the first place. After the earlier http.c commit,
the failure results in a warning printed to the user. In earlier
versions, the failure would cause a segfault.

Does not work. Even emits a warning with some compilers that the
attribute does not work on enums. It's likely that there is way to make
it work, but not worth the trouble.

Some http/1.0 implementations, like python's SimpleHTTPServer, can only support one client connection at a time. Making a second request while the first is still connected leads to a deadlock.

This change enables multiple connections for http/1.1 servers only, which need to support keepalive by default and should have no problem with concurrent requests.
