curl-openssl.m4: show correct output for OpenSSL v3
Using 3.0.0 versions configure should now show this:

checking for OpenSSL headers version... 3.0.0 - 0x300
checking for OpenSSL library version... 3.0.0
checking for OpenSSL headers and library versions matching... yes

This output doesn't actually change what configure generates but is only

m4: add security frameworks on Mac when compiling rustls
Previously compiling rustls on Mac would only complete if you also
compiled the SecureTransport TLS backend, which curl would prefer to
the Rust backend.

Appending these flags to LDFLAGS makes it possible to compile the
Rustls backend on Mac without the SecureTransport backend, which means
this patch will make it possible for Mac users to use the Rustls
backend for TLS.

configure: include <time.h> unconditionally
In 2682e5f5, several instances of AC_HEADER_TIME were removed since
it is a deprecated autoconf macro. However, this was the macro that
defined TIME_WITH_SYS_TIME, which was used to indicate that <time.h>
can be included alongside <sys/time.h>. TIME_WITH_SYS_TIME is still
used in the configure test body and since it is no longer defined,
<time.h> is *not* included on systems that have <sys/time.h>.

In particular, at least on musl libc and glibc, <sys/time.h> does
not implicitly include <time.h> and does not declare clock_gettime,
gmtime_r, or localtime_r. This causes configure to fail to detect
those functions.

The AC_HEADER_TIME macro deprecation text says

> All current systems provide time.h; it need not be checked for.
> Not all systems provide sys/time.h, but those that do, all allow
> you to include it and time.h simultaneously.

So, to fix this issue, simply include <time.h> unconditionally when
testing for time-related functions and in libcurl, and don't bother
checking for it.

f25f602ffd curl-functions.m4: remove inappropriate AC_REQUIRE
AC_REQUIRE means "if this macro hasn't been executed already, execute
it".  So in a wrapper around AC_RUN_IFELSE, AC_REQUIRE(AC_RUN_IFELSE)
isn't correct at that will execute AC_RUN_IFELSE without any arguments.

With autoconf 2.69 this is basically a no-op, but with autoconf 2.70,
AC_RUN_IFELSE without a default value when cross-compiling is fatal.
The result is that curl with autoconf 2.70 cannot cross-compile.

Cygwin and MinGW in order to avoid warnings for every executable built,
which spams the test suite output when using Cygwin's clang.

curl-compilers.m4: fix unknown-warning-option on Apple clang
Since 5598b0bd63, clang -v is used to
detect the clang version. The version number was expected to come after
the word "version". For Apple clang, this doesn't work as it has its
own versioning scheme.
The version number is now first searched after the string
"based on LLVM". This works for Apple clang before version 7, and also
for e.g. Ubuntu's clang up to version 3.7. If it's not found and the
version string contains "Apple LLVM version", clang version 3.7 is
assumed, which is the version that comes with Xcode 7. Otherwise, the
version number is still expected after the word "version", which works
for very old Apple clang versions.

curl-compilers.m4: accept -Og and -Ofast GCC flags
-Og, introduced in GCC 4.8, optimizes for debugging experience.
-Ofast, introduced in GCC 4.7, builds on -O3 and enables further
optimizations breaking strict standards compliance.
When specified in CFLAGS, these were always overridden by -O0 or -O2.
Fix this by adding them to flags_opt_all.

curl-compilers.m4: turn implicit function declarations into errors
This adds -Werror-implicit-function-declaration for GCC 2.95+ so that
these errors are visible at the point where they occur instead of only
at link time.
Implicit function declarations are illegal in C99 and C++ anyway, and
the same warning has been turned into an error for ICC in commit
3072c5b8a1.

b2dcf0347f curl-compilers.m4: improve detection of GCC's -fvisibility= flag
Some builds of GCC produce output on both stdout and stderr when --help
--verbose is used.  The 2>&1 redirection caused them to be arbitrarily
interleaved with each other because of stream buffering.  Consequently,
grep failed to match the fvisibility= string in the mixed output, even
though the string was present in GCC's standard output.

This led to silently disabling symbol hiding in some builds of curl.

d9f3b365a3 configure: ac_cv_ -> curl_cv_ for write-only vars
These configure vars are modified in a curl-specific way but never
evaluated or loaded from cache, even though they are designated as
_cv_. We could either implement proper AC_CACHE_CHECKs for them, or
remove them completely.

Fixes #603 as ac_cv_func_gethostbyname is no longer clobbered, and
AC_CHECK_FUNC(gethostbyname...) will no longer spuriously succeed after
the first configure run with caching.

`ac_cv_func_strcasecmp` is curious, see #770.

`eval "ac_cv_func_$func=yes"` can still cause problems as it works in
tandem with AC_CHECK_FUNCS and then potentially modifies its result. It
would be best to rewrite this test to use a new CURL_CHECK_FUNCS macro,
which works the same as AC_CHECK_FUNCS but relies on caching the values
of curl_cv_func_* variables, without modifiying ac_cv_func_*.

This only changed the prefix for 16 variables actually checked with
AC_CACHE_CHECK.
