	* process.cc (process_cache::process): Fix maximum process condition.

	* README: Add description for new -p/--process-cache option.
	* bsd_helper.cc (default_tun_check): Add kern.srv.process_cache_size
	entry to tunable_params. Set max value of kern.srv.request_threads
	to 310.
	* cygserver.cc (SERVER_VERSION): Set to 1.20.
	(print_usage): Print usage of new parameter -p.
	(main): Add process cache parameter handling. Accomodate new max
	value of request threads.
	* cygserver.conf: Add kern.srv.process_cache_size tunable parameter.
	Accomodate new max value of kern.srv.request_threads.
	* process.cc: Fix a comment.
	(process_cache::process_cache): Add max process cache size parameter.
	Change _cache_add_trigger to manual reset event.
	(struct pcache_wait_t): New struct used as parameter to
	pcache_wait_thread.
	(pcache_wait_thread): New thread function used for threaded process
	cache.
	(process_cache::wait_for_processes): Use threaded waiting if number
	of processes to wait for is bigger than 62. Always check all processes
	to avoid race under heavy load.
	(process_cache::sync_wait_array): Remove useless assert. Reset
	_cache_add_trigger right at the start since it's manual reset now.
	Accomodate threaded waiting.
	* process.h (process_cache::process_cache): Add max_procs parameter.
	(process_cache::_max_process_count): New member.
	(process_cache::_wait_array: Raise to allow up to 5 wait threads.
