sendf.c: added ability to call recv() before send() as workaround
WinSock destroys recv() buffer if send() is failed. As result - server
response may be lost if server sent it while curl is still sending
request. This behavior noticeable on HTTP server short replies if
libcurl use several send() for request (usually for POST request).
To workaround this problem, libcurl use recv() before every send() and
keeps received data in intermediate buffer for further processing.
connect: make sure that rc is initialized in singleipconnect()

checksrc: taught to skip comments
... but output non-stripped version of the line, even if that then can
make the script identify the wrong position in the line at
times. Showing the line stripped (ie without comments) is just too
surprising.
http2: Ensure that http2_handle_stream_close is called
This commit ensures that streams which was closed in on_stream_close
callback gets passed to http2_handle_stream_close. Previously, this
might not happen. To achieve this, we increment drain property to
forcibly call recv function for that stream.
To more accurately check that we have no pending event before shutting
down HTTP/2 session, we sum up drain property into
http_conn.drain_total. We only shutdown session if that value is 0.
With this commit, when stream was closed before reading response
header fields, error code CURLE_HTTP2_STREAM is returned even if
HTTP/2 level error is NO_ERROR. This signals the upper layer that
stream was closed by error just like TCP connection close in HTTP/1.
http2: Process paused data first before tear down http2 session
This commit ensures that data from network are processed before HTTP/2
session is terminated. This is achieved by pausing nghttp2 whenever
different stream than current easy handle receives data.
This commit also fixes the bug that sometimes processing hangs when
multiple HTTP/2 streams are multiplexed.
Previously, when a stream was closed with other than NGHTTP2_NO_ERROR
by RST_STREAM, underlying TCP connection was dropped. This is
undesirable since there may be other streams multiplexed and they are
very much fine. This change introduce new error code
CURLE_HTTP2_STREAM, which indicates stream error that only affects the
relevant stream, and connection should be kept open. The existing
CURLE_HTTP2 means connection error in general.

http2: drain the socket better...
... but ignore EAGAIN if the stream has ended so that we don't end up in
a loop. This is a follow-up to c8ab613 in order to avoid the problem d261652 was made to fix.

KNOWN_BUGS: remove 68, 70 and 72.
Due to their age (we don't fully know if they actually remain) and lack
of detail - very few people will bother to find out what they're about
or work on them. If people truly still suffer from any of these, I
assume they will be reported again and then we'll deal with them.

http2: fix connection reuse when PING comes after last DATA
It turns out the google GFE HTTP/2 servers send a PING frame immediately
after a stream ends and its last DATA has been received by curl. So if
we don't drain that from the socket, it makes the socket readable in
subsequent checks and libcurl then (wrongly) assumes the connection is
dead when trying to reuse the connection.
