libssh2 back-end returns CURLE_SSH error if the remote file
is not found. Expect instead CURLE_REMOTE_FILE_NOT_FOUND
which is sent by the libssh backend.

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
calling the client write procedure.
New test 230 checks this feature.

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.

If stdin is not a regular file, its content is memory-buffered to enable
a possible data "rewind".
In all cases, stdin data size is determined before real use to avoid
having an unknown part's size.
--libcurl generated code is left as an unbuffered stdin fread/fseek callback
part with unknown data size.
Buffering is not supported in deprecated curl_formadd() API.
This reverts commit f3e03f6c0a.
Caused memory leaks in the fuzzer, needs to be done differently.
Disable test 1553 for now too, as it causes memory leaks without this
commit!
When imap_done() got called before a connection is setup, it would try
to "finish up" and dereffed a NULL pointer.
Test case 1553 managed to reproduce. I had to actually use a host name
to try to resolve to slow it down, as using the normal local server IP
will make libcurl get a connection in the first curl_multi_perform()
loop and then the bug doesn't trigger.

When curl and libcurl are built with some protocols disabled, they stop
setting and receiving some options that don't make sense with those
protocols. In particular, when HTTP is disabled many options aren't set
that are used only by HTTP. However, some options that appear to be
HTTP-only are actually used by other protocols as well (some despite
having HTTP in the name) and should be set, but weren't. This change now
causes some of these options to be set and used for more (or for all)
protocols. In particular, this fixes tests 646 through 649 in an
HTTP-disabled build, which use the MIME API in the mail protocols.
... as the test cases themselves do that and it makes it easier to add
crazy test cases.
Test 800 updated to use user name + password that need quoting.
Test 856 updated to trigger an auth fail differently.

Before merging in the oss-fuzz corpora from Google, there are some changes
to the fuzzer.
- Add a read corpus script, to display corpus files nicely.
- Change the behaviour of the fuzzer so that TLV parse failures all now
go down the same execution paths, which should reduce the size of the
corpora.
- Make unknown TLVs a failure to parse, which should decrease the size
of the corpora as well.
Closes#1881
Don't make the fuzzer write out to stdout - instead write some of the

... instead of truncating them.
There's no fixed limit for acceptable cookie names in RFC 6265, but the
entire cookie is said to be less than 4096 bytes (section 6.1). This is
also what browsers seem to implement.
We now allow max 5000 bytes cookie header. Max 4095 bytes length per
cookie name and value. Name + value together may not exceed 4096 bytes.

The stub implementation is pre-loaded using LD_PRELOAD
and emulates common gssapi uses (only builds if curl is
initially built with gssapi support).
The initial tests are currently disabled for debug builds
as LD_PRELOAD is not used then.

Now that the form API is deprecated and not used anymore in curl tool,
a lot of its features left untested. Test 650 attempts to check all these
features not tested elsewhere.
curl_mime_encoder() is operational and documented.
curl tool -F option is extended with ";encoder=".
curl tool --libcurl option generates calls to curl_mime_encoder().
New encoder tests 648 & 649.
Test 1404 extended with an encoder specification.
This feature is badly supported in Windows: as a replacement, a caller has
to use curl_mime_data_cb() with fread, fseek and possibly fclose
callbacks to process opened files.
The cli tool and documentation are updated accordingly.
The feature is however kept internally for form API compatibility, with
the known caveats it always had.
As a side effect, stdin size is not determined by the cli tool even if
possible and this results in a chunked transfer encoding. Test 173 is
updated accordingly.
Additional mime-specific tests.
Existing tests updated to reflect small differences (Expect: 100-continue,
data size change due to empty lines, etc).
Option -F headers= keyword added to tests.
test1135 disabled until the entry point order change is resolved.
New example smtp-mime.
Examples postit2 and multi-post converted from form API to mime API.
Automake gets confused if you want to use C++ static libraries with C
code - basically we need to involve the clang++ linker. The easiest way
of achieving this is to rename the C code as C++ code. This gets us a
bit further along the path and ought to be compatible with Google's
version of clang.
- Start with the basic code from the ossfuzz project.
- Rewrite fuzz corpora to be binary files full of Type-Length-Value
data, and write a glue layer in the fuzzing function to convert
corpora into CURL options.
- Have supporting functions to generate corpora from existing tests
- Integrate with Makefile.am
Let's add a compile time safe API to select an SSL backend. This
function needs to be called *before* curl_global_init(), and can be
called only once.
Side note: we do not explicitly test that it is called before
curl_global_init(), but we do verify that it is not called multiple times
(even implicitly).
If SSL is used before the function was called, it will use whatever the
CURL_SSL_BACKEND environment variable says (or default to the first
available SSL backend), and if a subsequent call to
curl_global_sslset() disagrees with the previous choice, it will fail
with CURLSSLSET_TOO_LATE.
The function also accepts an "avail" parameter to point to a (read-only)
NULL-terminated list of available backends. This comes in real handy if
an application wants to let the user choose between whatever SSL backends
the currently available libcurl has to offer: simply call
curl_global_sslset(-1, NULL, &avail);
which will return CURLSSLSET_UNKNOWN_BACKEND and populate the avail
variable to point to the relevant information to present to the user.
Just like with the HTTP/2 push functions, we have to add the function
declaration of curl_global_sslset() function to the header file
*multi.h* because VMS and OS/400 require a stable order of functions
declared in include/curl/*.h (where the header files are sorted
alphabetically). This looks a bit funny, but it cannot be helped.

Closes#1808
The required low-level logic was already available as part of
`libssh2` (via `LIBSSH2_FLAG_COMPRESS` `libssh2_session_flag()`[1]
option.)
This patch adds the new `libcurl` option `CURLOPT_SSH_COMPRESSION`
(boolean) and the new `curl` command-line option `--compressed-ssh`
to request this `libssh2` feature. To have compression enabled, it
is required that the SSH server supports a (zlib) compatible
compression method and that `libssh2` was built with `zlib` support
enabled.
