http2: Ensure that http2_handle_stream_close is called
Previously, when HTTP/2 is enabled and used, and stream has content
length known, Curl_read was not called when there was no bytes left to
read. Because of this, we could not make sure that
http2_handle_stream_close was called for every stream. Since we use
http2_handle_stream_close to emit trailer fields, they were
effectively ignored. This commit changes the code so that Curl_read is
called even if no bytes left to read, to ensure that
http2_handle_stream_close is called for every stream.

multiplex: allow only once HTTP/2 is actually used
To make sure curl doesn't allow multiplexing before a connection is
upgraded to HTTP/2 (like when Upgrade: h2c fails), we must make sure the
connection uses HTTP/2 as well and not only check what's wanted.

Makefile.inc: s/curl_SOURCES/CURL_FILES
This allows the root Makefile.am to include the Makefile.inc without
causing automake to warn on it (variables named *_SOURCES are
magic). curl_SOURCES is then instead assigned properly in

ConnectionExists: with *PIPEWAIT, wait for connections
Try harder to prevent libcurl from opening up an additional socket when
CURLOPT_PIPEWAIT is set. Accomplished by letting ongoing TCP and TLS

test 1326: fix getting stuck on Windows due to incomplete request
The request needs to be read and send in binary mode in order to use
CRLF instead of LF. Adding --upload-file - causes curl to read stdin

cyassl: deal with lack of *get_peer_certificate
The function is only present in wolfssl/cyassl if it was built with

Also fix the mistake in configure that checks for the wrong lib name.
This commit adds trailer support in HTTP/2. In HTTP/1.1, chunked
encoding must be used to send trialer fields. HTTP/2 deprecated any
trandfer-encoding, including chunked. But trailer fields are now
always available.
Since trailer fields are relatively rare these days (gRPC uses them
extensively though), allocating buffer for trailer fields is done when
we detect that HEADERS frame containing trailer fields is started. We
use Curl_add_buffer_* functions to buffer all trailers, just like we
do for regular header fields. And then deliver them when stream is
closed. We have to be careful here so that all data are delivered to
upper layer before sending trailers to the application.
We can deliver trailer field one by one using NGHTTP2_ERR_PAUSE
mechanism, but current method is far more simple.
Another possibility is use chunked encoding internally for HTTP/2
traffic. I have not tested it, but it could add another overhead.
When NGHTTP2_ERR_PAUSE is returned from data_source_read_callback, we
might not process DATA frame fully. Calling nghttp2_session_mem_recv()
again will continue to process DATA frame, but if there is no incoming
frames, then we have to call it again with 0-length data. Without this,
on_stream_close callback will not be called, and stream could be hanged.

tool_paramhlp: Fixed display of URL index in password prompt for --next
Commit f3bae6ed73 added the URL index to the password prompt when using
--next. Unfortunately, because the size_t specifier (%zu) is not
supported by all sprintf() implementations we use the curl_off_t format
specifier instead. The display of an incorrect value arises on platforms
where size_t and curl_off_t are of a different size.
