This fixes GSSAPI builds with the libraries in a non-standard location.
The testing for recv() were failing because it failed to link
the Kerberos libraries, which are not needed for this or subsequent
tests.

With CMAKE_TRY_COMPILE_TARGET_TYPE set to STATIC_LIBRARY, the try_compile()
(which is used by check_c_source_compiles()) will build static library
instead of executable. This avoids linking additional libraries in and thus
speeds up those checks a little.
This commit also avoids #3743 (GSSAPI build errors) on itself with cmake
3.6 or above. That issue was fixed separately for all versions.
Ref: #3744
- Remove nneeded include_regular_expression.
It was setting what is already a default.
- Remove duplicated include.
- Don't check for pre-3.0.0 CMake version.
We already require at least 3.0.0, so it's just clutter.

The following snippet
```
int main()
{
CURL* hCurlHandle = curl_easy_init();
curl_easy_setopt(hCurlHandle, CURLOPT_URL, "http://example.com");
curl_easy_setopt(hCurlHandle, CURLOPT_PROXY, "1");
curl_easy_perform(hCurlHandle);
curl_easy_cleanup(hCurlHandle);
return 0;
}
```
triggers the following Valgrind warning

In case of an empty list, SORTing leads to the cmake error "list
sub-command SORT requires list to be present."
Closes https://github.com/curl/curl/pull/3736
Fish defines a vendor completions directory for completions that are not
installed as part of the fish project itself, and the vendor completions
are preferred if they exist. This prevents trying to overwrite the
builtin curl.fish completion (or creating file conflicts in distro
packaging).
Prefer the pkg-config defined location exported by fish, if it can be
found, and fall back to the correct directory defined by most systems.
Closes#3723

Just remove the redundant condition, which also makes it clear that
k->buf is always 0-terminated if this break is not hit.

- Fix clang string-plus-int warning.
Clang 8 warns about adding a string to an int does not append to the
string. Indeed it doesn't, but that was not the intention either. Use
array indexing as suggested to silence the warning. There should be no
functional changes.
(In other words clang warns about "foo"+2 but not &"foo"[2] so use the
latter.)

All Windows APIs have been natively UTF-16 since Windows 2000 and the
non-Unicode variants are just wrappers around them. Only Windows 9x
doesn't understand Unicode without the UnicoWS DLL. As later Visual
Studio versions cannot target Windows 9x anyway, using the ANSI API
doesn't really have any benefit there.
This avoids issues like KNOWN_BUGS 6.5.

Commit f5bc578f4c reintroduced the
warning fixed in commit 2f5f31bb57.
Extend fhnd's scope and reuse that variable instead of calling
_get_osfhandle a second time to fix the warning again.

- Improve console detection.
Prior to this change WriteConsole could be called to write to a handle
that may not be a console, which would cause an error. This issue is
limited to character devices that are not also consoles such as the null
device NUL.
