I also improved how NSS is detected by trying nss-config if pkg-config isn't
present, and as a last resort just use the lib name and force the user to
setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would
add a range of various libs that would almost never be quite correct.

Fix preprocessor conditional expression

Proper naming for the experimental compiler test and moved to *-compilers.m4

Moved *_CHECK_COMPILER_HALT_ON_ERROR and *_CHECK_COMPILER_ARRAY_SIZE_NEGATIVE to *-compilers.m4 along with other *_CHECK_COMPILER_*

Use autobuilds to verify if a couple of experimental compiler tests pass on all of them.
This will be removed in 24 or 48 hours.

- Based on bug report #2498665 (http://curl.haxx.se/bug/view.cgi?id=2498665)
by Daniel Black, I've now added magic to the configure script that makes it
use pkg-config to detect gnutls details as well if the existing method
(using libgnutls-config) fails. While doing this, I cleaned up and unified
the pkg-config usage when detecting openssl and nss as well.

Automatically detect OpenBSD's CA cert bundle.

Refactor configure script detection of functions used to set sockets into
non-blocking mode, and decouple function detection from function capability.

Initial attempt to detect at configuration time if the getaddrinfo()
function returns an addrinfo with an unfreeable ai_addr member ptr.
