Johannes Sixt 9374919442 Thread-safe xmalloc and xrealloc needs a recursive mutex

The mutex used to protect object access (read_mutex) may need to be
acquired recursively.  Introduce init_recursive_mutex() helper function
in thread-utils.c that constructs a mutex with the PHREAD_MUTEX_RECURSIVE
attribute.

pthread_mutex_init() emulation on Win32 is already recursive as it is
implemented on top of the CRITICAL_SECTION type, which is recursive.

Add do-nothing compatibility wrappers for pthread_mutexattr* functions.
