* Add psignal module for centralized signal handling
- Added pclsync/psignal.h with psignal_register() and psignal_check_pending() API
- Added pclsync/psignal.c with async-signal-safe handlers for SIGINT, SIGTERM, SIGHUP
- Implements flag-based deferred signal handling pattern
* Integrate psignal into main loop and remove conflicting handlers
- Added extern "C" linkage to psignal.h for C++ compatibility
- Integrated psignal_check_pending() into pclsync_lib.cpp main loop
- Integrated psignal_check_pending() into ptimer.c timer loop
- Removed conflicting signal handlers from pfs.c
* Migrate psync_set_signal to psignal module
- Added psignal_set_custom_handler() to psignal.h and psignal.c
- Replaced psync_set_signal() calls in pfs.c with psignal_set_custom_handler()
- Centralizes all signal handling in psignal module

psync_current_time is a global time_t written by timer_thread without
holding timer_mutex, while ptimer_register reads it under timer_mutex.
TSan reports the race at ptimer.c:152 (write) and ptimer.c:216 (read).
Replace all reads with __atomic_load_n and all writes with
__atomic_store_n using __ATOMIC_RELAXED. This covers the race sites in
ptimer.c and all external readers in plocalscan.c, pnetlibs.c, and
psynclib.c that access psync_current_time without any mutex.
Closes#333

excepions is read without holding timer_ex_mutex, but
ptimer_exception_handler() modifies it under the mutex.
Move the read inside the critical section to prevent the race.
Fixes GH #227
