Unsetting CURLOPT_NOBODY with 0L when doing HTTP has no documented
action but before 7.71.0 that used to switch back to GET and with this
change (assuming the method is still set to HEAD) this behavior is
brought back.

Fixes#5725Closes#5728
Stack overflows can occur with precisions for integers and floats.
Proof of concepts:
- curl_mprintf("%d, %.*1$d", 500, 1);
- curl_mprintf("%d, %+0500.*1$f", 500, 1);
Ideally, compile with -fsanitize=address which makes this undefined
behavior a bit more defined for debug purposes.
The format strings are valid. The overflows occur due to invalid
arguments. If these arguments are variables with contents controlled
by an attacker, the function's stack can be corrupted.
Also see CVE-2016-9586 which partially fixed the float aspect.

Verify that specified parameters are in range. If parameters are too
large, fail early on and avoid out of boundary accesses.
Also do not read behind boundaries of illegal format strings.
These are defensive measures since it is expected that format strings
are well-formed. Format strings should not be modifiable by user
input due to possible generic format string attacks.

GCC doesn't warn for unknown `-Wno-` options, except if there are other
warnings or errors [0]. This was problematic with `CURL_WERROR` as that
warning-as-error cannot be suppressed. Notably, this always happened
with `-Wno-pedantic-ms-format` when not targeting Windows. So test for
the positive form of the warning instead, which should always result in
a diagnostic if unknown.

timeval::tv_usec might be a 32-bit integer and timespec::tv_nsec might
be a 64-bit integer. This is the case when building for recent macOS
versions, for example. Just treat tv_usec as an int, which should
hopefully always be sufficient on systems with
`HAVE_CLOCK_GETTIME_MONOTONIC`.

It confuses code analyzers with its use of -1 for unsigned value. Also,
a check that's not normally used in strdup() code - and not necessary.

This is required after https://github.com/cloudflare/quiche/pull/593
moved BoringSSL around slightly.
This also means that Go is not needed to build BoringSSL anymore (the
one provided by quiche anyway).
Closes#5691
When using `--enable-warnings`, it was not possible to disable warnings
via CFLAGS that got explicitly enabled. Now warnings are not enabled
anymore if they are explicitly disabled (or enabled) in CFLAGS. This
works for at least GCC, clang, and TCC as they have corresponding
`-Wno-` options for every warning.

... to use the maximum value for 'size_t' when detecting integer overflow.
Changed the limit to max/4 as already that seems unreasonably large.
Codacy didn't like the previous approach.

Use the unsigned type (size_t) in the arithmetic of pointers. In this
