Add the '-Ae' flag and check for gethrtime() on HPUX

Check if CLOCK_MONOTONIC defined before using it - if not, use
gethrtime() if it's available, otherwise fall back to the old
behavior.

libzmq master (3.1) is not ABI compatible with libzmq 2.1.x or 3.0 (removed
functionality), hence the ABI version needs to be set to 3.

This patch simplifies the whole codebase significantly,
including dropping depedency on libuuid.

 - Added a macro for checking clang compiler
 - Moved basic compiler checks to a macro
 - Added a macro for checking if compiler supports a flag
 - Added --enable-debug flag
 - Added a macro for running normal autoconf check with compiler flags
 - Added a macro for checking for verbose flag for different compilers (-Wall)
 - Added a macro for turning on strict standards compliance
 - Added a macro for turning warnings to errors
 - Added a macro for checking if compiler supports given pragma
 - Most of the flags now go through checks if the compilers supports them
   rather than enumerating different compilers
 - Added DSO symbol visibility for sun compiler
 - Enabled verbose mode for sun compiler
 - Fixed build for ICC 12.x by adding -wd279 to size_t checks
 - Removed pkg-config checks as those don't seem to be used anywhere

On systems using GCC 4.0 or newer which support symbol visibility in shared
libraries, use -fvisibility=hidden and only export explict API functions
defined in zmq.cpp. We do not enable -fvisibility on MinGW since this uses a
separate mechanism (__declspec).

The patch tests that the C and C++ compilers actually exist
and work. autoconf seems to default to 'g++' when C++ compiler is not
found, which causes the following error (when the compiler isn't
there):

checking for uuid_generate in -luuid... no
configure: error: cannot link with -luuid, install uuid-dev.

The config.log contains the real error message "g++ command not found"
but the error message shown to the user is misleading.

I ran autoupdate on the configure.in, which generated most of the
patch attached. There is also a small manual fix in which removes the
warning "Remember to add LT_INIT to configure.in" which I assume is
because AC_PROG_LIBTOOL was called inside a macro.

This conditional is unnecessary as BUILD_PGM can be negated in the test.

After long discussions in IRC we came to conclusion that there is no
elegant way to handle static builds with MinGW32. This patch sets
AC_DISABLE_STATIC by default on MinGW32 and Cygwin
Signed-off-by: Mikko Koppanen <mkoppanen@php.net>

MinGW32 defines __int64_t as long long, which causes the build to fail
unless -Wno-long-long is used. In addition the shutdown_stress test
isn't currently compatible with Win.
