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.
Closes#6859
AC_HELP_STRING is deprecated in 2.70+ and I believe AS_HELP_STRING works
already since 2.59 so bump the minimum required version to that.

Unfortunately, this option is not detecting the same issues as clang's

mistakes.

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.

Closes#5141
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.

AmiSSL is an Amiga native library which provides a wrapper over OpenSSL.
It also requires all programs using it to use bsdsocket.library
directly, rather than accessing socket functions through clib, which
libcurl was not necessarily doing previously. Configure will now check
for the headers and ensure they are included if found.

This enables the following additional warnings:

-Warray-bounds=2 instead of the default 1
-Wformat=2, but only for GCC 4.8+ as Wno-format-nonliteral is not
respected for older versions
-Wunused-const-variable, which enables level 2 instead of the default 1

- Add OpenSSL 1.1.1 to the header/library version lists.
- Detect OpenSSL 1.1.1 library using its function ERR_clear_last_mark,
which was added in that version.
Prior to this change an erroneous header/library mismatch was caused by
lack of OpenSSL 1.1.1 detection. I tested using openssl-1.1.1-pre1.
The logic tries to figure out what the path separator in the $PATH
variable is, but if there's only one directory in the $PATH it
fails. This change make configure *guess* on colon instead of erroring
out, simply because that is probably the more common character.
PATH_SEPARATOR can always be set by the user to override the guessing.
(tricky bug to reproduce, as in my case for example the configure script
requires binaries in more than one directory so passing in a PATH with a
single dir fails.)

When building with Cygwin or MinGW, libtool uses a wrapper executable
instead of a wrapper script [1], which is written in C and throws
missing-variable-declarations warnings. Don't enable these warnings on
Cygwin and MinGW in order to avoid warnings for every executable built,
which spams the test suite output when using Cygwin's 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.
