Replace our hacked version of ax_pthread.m4 with latest upstream version. Our version was different from the upstream version in that we tried to use all possible pthread-related flags that the compiler accepts, rather than just the first one that works. That change was made in commit e48322a6d6cfce1ec52ab303441df329ddbc04d1, to work-around a bug affecting GCC versions 3.2 and below (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=8888), although we didn't realize that it was a GCC bug at the time. We hardly care about that old GCC versions anymore, so we no longer need that workaround. This fixes the macro for compilers that print warnings with the chosen flags. That's pretty annoying on its own right, but it also inconspicuously disabled thread-safety, because we refused to use any pthread-related flags if the compiler produced warnings. Max Filippov reported that problem when linking with uClibc and OpenSSL. The warnings-check was added because the workaround for the GCC bug caused warnings otherwise, so it's no longer needed either. We can just use the upstream version as is. If you really want to compile with GCC version 3.2 or older, you can still work-around it manually by setting PTHREAD_CFLAGS="-pthread -lpthread" manually on the configure command line. Backpatch to 9.5. I don't want to unnecessarily rock the boat on stable branches, but 9.5 seems like fair game.

Upgrade to Autoconf version 2.53. Replaced many custom macro calls with new or now-built-in versions. Make sure that all calls to AC_DEFINE have a third argument, for possible use of autoheader in the future.

Fix configure's AC_CHECK_DECLS tests to work correctly with clang. The test case that Autoconf uses to discover whether a function has been declared doesn't work reliably with clang, because clang reports a warning not an error if the name is a known built-in function. On some platforms, this results in a lot of compile-time warnings about strlcpy and related functions not having been declared. There is a fix for this (by Noah Misch) in the upstream Autoconf sources, but since they've not made a release in years and show no indication of doing so anytime soon, let's just absorb their fix directly. We can revert this when and if we update to a newer Autoconf release. Back-patch to all supported branches. Discussion: https://postgr.es/m/26819.1542515567@sss.pgh.pa.us

Add configure infrastructure (--with-llvm) to enable LLVM support. LLVM will be used for *optional* Just-in-time compilation support. This commit just adds the configure infrastructure that detects LLVM. No documentation has been added for the --with-llvm flag, that'll be added after the actual supporting code has been added.

ICU support Add a column collprovider to pg_collation that determines which library provides the collation data. The existing choices are default and libc, and this adds an icu choice, which uses the ICU4C library. The pg_locale_t type is changed to a union that contains the provider-specific locale handles. Users of locale information are changed to look into that struct for the appropriate handle to use. Also add a collversion column that records the version of the collation when it is created, and check at run time whether it is still the same. This detects potentially incompatible library upgrades that can corrupt indexes and other structures. This is currently only supported by ICU-provided collations. initdb initializes the default collation set as before from the `locale -a` output but also adds all available ICU locales with a "-x-icu" appended. Currently, ICU-provided collations can only be explicitly named collations. The global database locales are still always libc-provided. ICU support is enabled by configure --with-icu.
