Thread: pgsql-server: win32 doesn't support a static initializer for mutexes,

Log Message:
-----------
win32 doesn't support a static initializer for mutexes, thus the first
user must initialize the lock. The problem are concurrent "first" users
- the pthread_mutex_t initialization must be synchronized.
The current implementation is broken, the attached patches fixes that:
mutex_initlock is a spinlock. If the pthread_mutex_t mutex is not
initialized, then the spinlock is acquired, if the pthread_mutex_t is
initialized if it's not yet initialized and then the spinlock is
dropped.
