atomic: revisit the atomic operation checks and their usage
* configure.ac:
Check for working Solaris/NetBSD-style atomic.h independly on OS.
Add check for GCC-style __sync_*() builtins.
New defines: XS_ATOMIC_GCC_SYNC, XS_ATOMIC_SOLARIS.
Removed define: XS_FORCE_MUTEXES.
* src/atomic_counter.hpp:
(atomic_counter_t::add):
(atomic_counter_t::sub):
* src/atomic_ptr.hpp:
(atomic_ptr_t::xchg):
(atomic_ptr_t::cas):
Use result of these checks.
Preference order:
1. GCC-style __sync_*() builtins
2. Inline asm (x86, x86-64, armv7a)
3. Solaris/NetBSD-style atomic.h, Windows-specific API
4. Fallback to mutex-based implementation
