It needs to parse correctly. Otherwise it could be tricked into letting
through a-f using host names that libcurl would then resolve. Like
'[ab.be]'.

This is only the libcurl part that provides the information. There's no
user of the parsed value. This change includes three new tests for the
parser.

With CURLOPT_TIMECONDITION set, a header is automatically added (e.g.
If-Modified-Since). Allow this to be replaced or suppressed with

... to make the host name "usable". Store the scope id and put it back

Also makes curl_url_set() syntax check CURLUPART_HOST.
Fixes#3817Closes#3822
This limits all accepted input strings passed to libcurl to be less than
CURL_MAX_INPUT_LENGTH (8000000) bytes, for these API calls:
curl_easy_setopt() and curl_url_set().
The 8000000 number is arbitrary picked and is meant to detect mistakes
or abuse, not to limit actual practical use cases. By limiting the
acceptable string lengths we also reduce the risk of integer overflows
all over.
NOTE: This does not apply to `CURLOPT_POSTFIELDS`.
Test 1559 verifies.
Closes#3805
Make sure to run curl_global_cleanup() when shutting down the test
suite to release any resources allocated in the SSL setup. This is
clearly visible when running tests with PolarSSL where the thread
lock calloc() memory which isn't released when not running cleanup.

Follow-up to 8eddb8f425.
If the cookieinfo pointer is NULL there really is nothing to save.
Without this fix, we got a problem when a handle was using shared object
with cookies and is told to "FLUSH" it to file (which worked) and then
the share object was removed and when the easy handle was closed just
afterwards it has no cookieinfo and no cookies so it decided to save an
empty jar (overwriting the file just flushed).
Test 1905 now verifies that this works.

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

Test 1591 checks that trailing headers can be sent using libcurl.

The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than

The function identifying a leading "scheme" part of the URL considered a
few letters ending with a colon to be a scheme, making something like
"short:80" to become an unknown scheme instead of a short host name and
a port number.

Also fixed test203 to use file_pwd to make it get the correct path on

Closes https://github.com/curl/curl/pull/3037
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.
