CURLOPT_HEADERFUNCTION.3: Document that size is always 1
For compatibility with `fwrite`, the `CURLOPT_HEADERFUNCTION` callback
is passed two `size_t` parameters which, when multiplied, designate the
number of bytes of data passed in. In practice, CURL always sets the
first parameter (`size`) to 1.
This practice is also enshrined in documentation and cannot be changed
in future. The documentation states that the default callback is
`fwrite`, which means `fwrite` must be a suitable function for this
purpose. However, the documentation also states that the callback must
return the number of *bytes* it successfully handled, whereas ISO C
`fwrite` returns the number of items (each of size `size`) which it
wrote. The only way these numbers can be equal is if `size` is 1.
Since `size` is 1 and can never be changed in future anyway, document
that fact explicitly and let users rely on it.

The comment was confusing and suggested that setting CURLOPT_NOPROGRESS
to 0L would both enable and disable debug output at the same time, like
a Schrödinger's cat of CURLOPTs.

ngtcp2: Support the latest update key callback type

Several days ago the ngtcp2_update_key callback function prototype was
changed in ngtcp2/ngtcp2@42ce09c. Though it would be possible to
fix up our cb_update_key for that change they also added
ngtcp2_crypto_update_key_cb which does the same thing so we'll use that

winbuild: Document CURL_STATICLIB requirement for static libcurl
A static libcurl (ie winbuild mode=static) requires that the user define
CURL_STATICLIB when using it in their application. This is already
covered in the FAQ and INSTALL.md, but is a pretty important point so
now it's noted in the BUILD.WINDOWS.txt as well.

runtests: introduce --shallow to reduce huge torture tests
When set, shallow mode limits runtests -t to make no more than NUM fails
per test case. If more are found, it will randomly discard entries until
the number is right. The random seed can also be set.
This is particularly useful when running MANY tests as then most torture
failures will already fail the same functions over and over and make the
total operation painfully tedious.
This makes them never to be considered "the oldest" to be discarded when
reaching the connection cache limit. The reasoning here is that
CONNECT_ONLY is primarily used in combination with using the
connection's socket post connect and since that is used outside of
curl's knowledge we must assume that it is in use until explicitly
closed.

tests: make it possible to set executable extensions
This enables the use of Windows Subsystem for Linux (WSL) to run the
testsuite against Windows binaries while using Linux servers.
This commit introduces the following environment variables:
- CURL_TEST_EXE_EXT: set the executable extension for all components
- CURL_TEST_EXE_EXT_TOOL: set it for the curl tool only
- CURL_TEST_EXE_EXT_SSH: set it for the SSH tools only
Later testcurl.pl could be adjusted to make use of those variables.
- CURL_TEST_EXE_EXT_SRV: set it for the test servers only
(This is one of several commits to support use of WSL for the tests.)

setopt: Fix ALPN / NPN user option when built without HTTP2

Prior to this change it was impossible to disable ALPN / NPN if libcurl

CURLE_UNKNOWN_OPTION and the respective internal option would not be
set. That was incorrect since ALPN and NPN are used independent of

configure: enable IPv6 support without `getaddrinfo`
This makes it possible to recognize and connect to literal IPv6

case for the CMake build. This affects e.g. classic MinGW because it
still targets Windows 2000 by default, where `getaddrinfo` is not
available, but general IPv6 support is.
Instead of checking for `getaddrinfo`, check for `sockaddr_in6` as the
CMake build does.

build: Disable Visual Studio warning "conditional expression is constant"
- 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.
