Refuse to operate when given path components featuring byte values lower
than 32.
Previously, inserting a %00 sequence early in the directory part when
using the 'singlecwd' ftp method could make curl write a zero byte
outside of the allocated buffer.
Test case 340 verifies.

- Add new option CURLOPT_RESOLVER_START_FUNCTION to set a callback that
will be called every time before a new resolve request is started
(ie before a host is resolved) with a pointer to backend-specific
resolver data. Currently this is only useful for ares.
- Add new option CURLOPT_RESOLVER_START_DATA to set a user pointer to
pass to the resolver start callback.

Test 319 checks proper raw mode data with non-chunked gzip
transfer-encoded server data.

RFC 5321 4.1.1.4 specifies the CRLF terminating the DATA command
should be taken into account when chasing the <CRLF>.<CRLF> end marker.
Thus a leading dot character in data is also subject to escaping.
Tests 911 and test server are adapted to this situation.
New tests 951 and 952 check proper handling of initial dot in data.
Closes #2304

If CURL_DOES_CONVERSION is enabled, uploaded LFs are mapped to CRLFs,
giving a result that is different from what is expected.
This commit avoids using CURLOPT_TRANSFERTEXT and directly encodes data
to upload in ascii.

... unless CURLOPT_UNRESTRICTED_AUTH is set to allow them. This matches how
curl already handles Authorization headers created internally.
Note: this changes behavior slightly, for the sake of reducing mistakes.

vtls.c:multissl_init() might do a curl_free() call so strip that out to
make this work with more builds. We just want to verify that
memorytracking works so skipping one line is no harm.

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.
Closes #2235

Decoding loop implementation did not concern the case when all
received data is consumed by Brotli decoder and the size of decoded
data internally hold by Brotli decoder is greater than CURL_MAX_WRITE_SIZE.
For content with unencoded length greater than CURL_MAX_WRITE_SIZE this
can result in the loss of data at the end of content.
Closes #2194

Move curl_mime_initpart() and curl_mime_cleanpart() calls to lower-level
functions dealing with UserDefined structure contents.
This avoids memory leakages on curl-generated part mime headers.
New test 2073 checks this using the cli tool --next option: it
triggers a valgrind error if bug is present.

- When zlib version is < 1.2.0.4, process gzip trailer before considering
extra data as an error.
- Inflate with Z_BLOCK instead of Z_SYNC_FLUSH to maximize correct data
and minimize corrupt data output.
- Do not try to restart deflate decompression in raw mode if output has
started or if the leading data is not available anymore.
- New test 232 checks inflating raw-deflated content.

This reverts commit 9ffad8eb1329bb35c8988115ac7ed85cf91ef955.
It was actually added rather recently in 8e8afa82cbb629 due to a crash
that would otherwise happen in the RTSP code. As I don't think we've
fixed that behavior yet, we better keep this work-around until we have
fixed it better.

This uses the brotli external library (https://github.com/google/brotli).
Brotli becomes a feature: additional curl_version_info() bit and
structure fields are provided for it and CURLVERSION_NOW bumped.
Tests 314 and 315 check Brotli content unencoding with correct and
erroneous data.
Some tests are updated to accomodate with the now configuration dependent
parameters of the Accept-Encoding header.

This is implemented as an output streaming stack of unencoders, the last

By properly keeping track of the last entry in the list of URLs/uploads
to handle, curl now avoids many meaningless traverses of the list which
speeds up many-URL handling *MASSIVELY* (several magnitudes on 100K
URLs).
Added test 1291, to verify that it doesn't take ages - but we don't have
any detection of "too slow" command in the test suite.
