Removed weak attribute from debug hooks (psys_debug_abort_on_sqllock and psys_debug_configure_core_dump). Made functions static in psys.c and removed declarations from psys.h. Functions can no longer be overridden by external libraries, preventing potential code execution and security bypass.
Fixes#289

The weak/strong symbol approach requires that psql.c undefs the debug
macros to define function implementations. This means functions in psql.c
call psql_lock()/psql_unlock() as functions, not macros.
In debug builds, these must be strong overrides that call the _do_
variants to properly maintain lockctr/rdlockctr. Without these overrides,
the weak stubs are used which don't update counters, causing assertion
failures in psql_unlock().
Added strong overrides in psql_debug.c for:
- psql_lock() -> psql_do_lock(__FILE__, __LINE__)
- psql_rdlock() -> psql_do_rdlock(__FILE__, __LINE__)
- psql_statement() (calls psql_do_lock directly)
Also made psql_statement, psql_start, and all query/prepare functions
weak in psql.c to allow debug overrides.
Fixes#138
