Also, use `CURLRES_IPV6` only for actual DNS resolution, not for IPv6
address support. This makes it possible to connect to IPv6 literals by
setting `ENABLE_IPV6` even without `getaddrinfo` support. It also fixes
the CMake build when using the synchronous resolver without
`getaddrinfo` support.

- Disable warning C4127 "conditional expression is constant" globally
in curl_setup.h for when building with Microsoft's compiler.
This mainly affects building with the Visual Studio project files found
in the projects dir.
Prior to this change the cmake and winbuild build systems already
disabled 4127 globally for when building with Microsoft's compiler.
Also, 4127 was already disabled for all build systems in the limited
circumstance of the WHILE_FALSE macro which disabled the warning
specifically for while(0). This commit removes the WHILE_FALSE macro and
all other cruft in favor of disabling globally in curl_setup.
Background:
We have various macros that cause 0 or 1 to be evaluated, which would
cause warning C4127 in Visual Studio. For example this causes it:
#define Curl_resolver_asynch() 1
Full behavior is not clearly defined and inconsistent across versions.
However it is documented that since VS 2015 Update 3 Microsoft has
addressed this somewhat but not entirely, not warning on while(true) for
example.
Prior to this change some C4127 warnings occurred when I built with
Visual Studio using the generated projects in the projects dir.

This commit adds curl_multi_wakeup() which was previously in the TODO
list under the curl_multi_unblock name.
On some platforms and with some configurations this feature might not be
available or can fail, in these cases a new error code
(CURLM_WAKEUP_FAILURE) is returned from curl_multi_wakeup().

Improved estimation of expected_len and updated related comments;
increased strictness of QNAME-encoding, adding error detection for empty
labels and names longer than the overall limit; avoided treating DNAME
as unexpected;
updated unit test 1655 with more thorough set of proofs and tests

Classic MinGW / MSYS 1 doesn't support `MSYS2_ARG_CONV_EXCL`, so this

- Use FORMAT_MESSAGE_IGNORE_INSERTS to ignore format specifiers in
Windows error strings.
Since we are not in control of the error code we don't know what
information may be needed by the error string's format specifiers.
Prior to this change Windows API error strings which contain specifiers
(think specifiers like similar to printf specifiers) would not be shown.
The FormatMessage Windows API call which turns a Windows error code into
a string could fail and set error ERROR_INVALID_PARAMETER if that error
string contained a format specifier. FormatMessage expects a va_list for
the specifiers, unless inserts are ignored in which case no substitution
is attempted.

This way, we always have exactly one slash after the host name, making
the tests pass when curl is compiled with the MSYS GCC.
Closes https://github.com/curl/curl/pull/4512
The MSYS system on Windows can run the test suite for curl built with
any toolset. When built with the MSYS GCC, curl uses Unix line endings,
while it uses Windows line endings when built with the MinGW GCC, and
`^O` reports 'msys' in both cases. Use the curl executable itself to
determine the line endings instead, which reports 'x86_64-pc-msys' when
built with the MSYS GCC.
Closes https://github.com/curl/curl/pull/4506
The URL extracted with CURLINFO_EFFECTIVE_URL was returned as given as
input in most cases, which made it not get a scheme prefixed like before
if the URL was given without one, and it didn't remove dotdot sequences
etc.
Added test case 1907 to verify that this now works as intended and as
before 7.62.0.

The 'share object' only sets the storage area for cookies. The "cookie
engine" still needs to be enabled or activated using the normal cookie
options.
This caused the curl command line tool to accidentally use cookies
without having been told to, since curl switched to using shared cookies
in 7.66.0.
