This reverts commit 46cb70e9.

Bug: http://curl.haxx.se/mail/lib-2016-01/0031.html

Discussed in https://github.com/bagder/curl/pull/564

Use the ACE form of IDN hostnames as key in the connection cache.  Add
new tests.

Closes #592

- Fix ALPN reply detection.

- Wrap nghttp2 code in ifdef USE_NGHTTP2.


Prior to this change ALPN and HTTP/2 did not work properly in mbedTLS.

Check that the trailer buffer exists before attempting a client write
for trailers on stream close.

Refer to comments in https://github.com/bagder/curl/pull/564

Mistake from commit a464f338

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.

Closes #584

Patch-by: c0ff

- Add to both curl_global_init.3 and libcurl.3 the caveat for Windows
that initializing libcurl via a DLL's DllMain or static initializer
could cause a deadlock.

MSYS would otherwise turn a /-style path into a C:\-style path.

While still using datacheck mode binary for the inline reply data.

Move the text-mode conversion for reply/replycheck from the verify
section into the load section and add support for 4 more check parts.

Not converting to double caused small timeouts to be skipped.

Not converting to double caused small timeouts to be skipped.

Previously file.txt[CR][LF] would have been returned as file.tx
(without the last t) if filetype is symlink. Now the t is
included and the internal item_length includes the zero byte.

Spotted using test 576 on Windows.

Follow up on b064ff0c, thanks Daniel.

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
src/Makefile.am only.

Closes #577

Try harder to prevent libcurl from opening up an additional socket when
CURLOPT_PIPEWAIT is set. Accomplished by letting ongoing TCP and TLS
handshakes complete first before the decision is made.

Closes #575

This makes it easier for emacs users to automatically get the right
2-space indentation when they edit curl source files.

c++-mode is in there as well because Emacs can't easily know if
something is a C or C++ header.

Closes #574

This patch was "nicked" from the MINGW-packages project by Daniel.

This patch is adopted from the MINGW-packages project. It makes it
possible to build curl both shared and static again.
