This adds the CURLOPT_TRAILERDATA and CURLOPT_TRAILERFUNCTION
options that allow a callback based approach to sending trailing headers
with chunked transfers.
The test server (sws) was updated to take into account the detection of the
end of transfer in the case of trailing headers presence.
Test 1591 checks that trailing headers can be sent using libcurl.

In order for this API to fully work for libcurl itself, it now offers a
CURLU_GUESS_SCHEME flag that makes it "guess" scheme based on the host
name prefix just like libcurl always did. If there's no known prefix, it
will guess "http://".
Separately, it relaxes the check of the host name so that IDN host names
can be passed in as well.
Both these changes are necessary for libcurl itself to use this API.

Previously, the macro TEST_HANG_TIMEOUT was unused, but since there is
looping going on, we might as well add timing instead of removing it.
Closes#2853
It was previously erroneously skipped in some situations.
libtest/libntlmconnect.c wrongly depended on wrong behavior (that it
would get a zero timeout) when no handles are "running" in a multi
handle. That behavior is no longer present with this fix. Now libcurl
will always return a -1 timeout when all handles are completed.

Since 467da3af0, lib1521.c is generated instead of checked in. According
to the commit message, the intention was to remove it from the tarball
as well. However, it is still present when running make dist. To remove
it, add it to nodist_lib1521_SOURCES. This also means there is no need
for the manually added dist-rule in the Makefile.
Also update CMakelists.txt to handle the fact that we now may have
nodist_SOURCES.
This avoids appending error data to already existing good data.

A mime tree attached to an easy handle using CURLOPT_MIMEPOST is
strongly bound to the handle: there is a pointer to the easy handle in
each item of the mime tree and following the parent pointer list
of mime items ends in a dummy part stored within the handle.
Because of this binding, a mime tree cannot be shared between different
easy handles, thus it needs to be cloned upon easy handle duplication.
There is no way for the caller to get the duplicated mime tree
handle: it is then set to be automatically destroyed upon freeing the
new easy handle.
New test 654 checks proper mime structure duplication/release.
Add a warning note in curl_mime_data_cb() documentation about sharing
user data between duplicated handles.

Both these tests run the same underlying test code: libntlmconnect.c -
this test code made some assumptions about socket ordering when it used
curl_easy_fdset() and when we changed timing or got accidental changes
in libcurl the tests would fail.
The tests verify that the different transfers keep using the same
connections, which I now instead made sure by adding the number of bytes
each transfer gets and then verifies that they always get the same
amount as when these tests worked.
Closes#1576
mk-lib1521.pl generates a test program (lib1521.c) that calls

when doing this.
The perl script needs to be manually rerun when we add new options.

Use CURLMcode for variable 'res' and cast to int where necessary

long is 32 bits while size_t is 64 bits on MinGW-w64, so
typecheck-gcc.h complains when using size_t for a long option.
Also, curl_socket_t is unsigned long long rather than int.
Windows does not allow setting the locale with environment variables (as
the test attempted to do), so the test failed when run with a user
locale that has a comma as radixchar. Changed the test to call
setlocale() explicitly to ensure that a known working locale is set even
on Windows.
system.h is aimed to replace curlbuild.h at a later point in time when
we feel confident system.h works sufficiently well.
curl/system.h is currently used in parallel with curl/curlbuild.h
curl/system.h determines a data sizes, data types and include file
status based on available preprocessor defines instead of getting
generated at build-time. This, in order to avoid relying on a build-time
generated file that makes it complicated to do 32 and 64 bit bields from
the same installed set of headers.
Test 1541 verifies that system.h comes to the same conclusion that
curlbuild.h offers.

We're mostly saying just "curl" in lower case these days so here's a big

To avoid that they cause problems with system includes, we include
curl_printf.h after any system headers. That makes the three last
headers to always be, and we keep them in this order:

curl_memory.h

The define is not in our name space and is therefore not protected by
our API promises.
It was only really used by libcurl internals but was mostly erased from
there already in 8aabbf5 (March 2015). This is supposedly the final
death blow to that define from everywhere.
As a side-effect, making sure _MPRINTF_REPLACE is gone and not used, I
made the lib tests in tests/libtest/ use curl_printf.h for its redefine
magic and then subsequently the use of sprintf() got banned in the tests
as well (as it is in libcurl internals) and I then replaced them all
with snprintf().
In the unlikely event that any users is actually using this define and
gets sad by this change, it is very easily copied to the user's own
code.
This prevents valgrind from reporting possibly lost memory that NSPR
uses for file descriptor cache and other globally allocated internal
data structures.
