In some situations, it was possible that a transfer was setup to
use an specific IP version, but due do DNS caching or connection
reuse, it ended up using a different IP version from requested.
This commit changes the effect of CURLOPT_IPRESOLVE from simply
restricting address resolution to preventing the wrong connection
type being used, when choosing a connection from the pool, and
to restricting what addresses could be used when establishing
a new connection.
It is important that all addresses versions are resolved, even if
not used in that transfer in particular, because the result is
cached, and could be useful for a different transfer with a
different CURLOPT_IPRESOLVE setting.

Also added 'CURL_SMALLSENDS' to make Curl_write() send short packets,
which helped verifying this even more.
Add test 363 to verify.

When hyper is used, it emits uppercase hexadecimal numbers for chunked
encoding lengths. Without hyper, lowercase hexadecimal numbers are used.
This change adds preprocessor statements to tests where this is an
issue, and adapts the fixtures to match.

When a TLS server requests a client certificate during handshake and
none can be provided, libcurl now returns this new error code
CURLE_SSL_CLIENTCERT
Only supported by Secure Transport and OpenSSL for TLS 1.3 so far.

A struct bufref holds a buffer pointer, a data size and a destructor.
When freed or its contents are changed, the previous buffer is implicitly
released by the associated destructor. The data size, although not used
internally, allows binary data support.
A unit test checks its handling methods: test 1661

This reverts commit 1cba36d216.
CMake provides properties that can be set on a target to rename the
output artifact without changing the name of a target.
Ref: #6899
When the host name in a URL is given as an IPv4 numerical address, the
address can be specified with dotted numericals in four different ways:
a32, a.b24, a.b.c16 or a.b.c.d and each part can be specified in
decimal, octal (0-prefixed) or hexadecimal (0x-prefixed).
Instead of passing on the name as-is and leaving the handling to the
underlying name functions, which made them not work with c-ares but work
with getaddrinfo, this change now makes the curl URL API itself detect
and "normalize" host names specified as IPv4 numericals.
The WHATWG URL Spec says this is an okay way to specify a host name in a
URL. RFC 3896 does not allow them, but curl didn't prevent them before
and it seems other RFC 3896-using tools have not either. Host names used
like this are widely supported by other tools as well due to the
handling being done by getaddrinfo and friends.
I decided to add the functionality into the URL API itself so that all
users of these functions get the benefits, when for example wanting to
compare two URLs. Also, it makes curl built to use c-ares now support
them as well and make curl builds more consistent.
The normalization makes HTTPS and virtual hosted HTTP work fine even
when curl gets the address specified using one of the "obscure" formats.
Test 1560 is extended to verify.

According to Microsoft document MS-NLMP, current flags usage is not
accurate: flag NTLMFLAG_NEGOTIATE_NTLM2_KEY controls the use of
extended security in an NTLM authentication message and NTLM version 2
cannot be negotiated within the protocol.
The solution implemented here is: if the extended security flag is set,
prefer using NTLM version 2 (as a server featuring extended security
should also support version 2). If version 2 has been disabled at
compile time, use extended security.
Tests involving NTLM are adjusted to this new behavior.

This was previously defined by the obsolete AC_TYPE_SIGNAL macro,
which was removed in 2682e5f5. The deprecation text says
> Your code may safely assume C89 semantics that RETSIGTYPE is void.
So, remove it and just use void instead.
Closes#6861
After 957bc1881e686f9714c4e6a01bf33535091f0e21, we no longer compute an
expected_size for directories. This has the upshot that when we compare
even an empty Range with the available size, we fail.
This brings back the previous behaviour, which was to succeed, but with
empty content. This also removes the "Accept-ranges: bytes" header,
which is nonsensical on directories.

When asked to resume a download, libcurl will convert that to HTTP logic
and if then the entire file is already transferred it will result in a
416 response from the HTTP server. With CURLOPT_FAILONERRROR set in that
scenario, it should *not* lead to an error return.
