Add apr_threadattr_guardsize_set function, which allows changing

the thread guard area size attribute for newly created threads.

* configure.in: Check for pthread_attr_setguardsize.

* include/apr_thread_proc.h (apr_threadattr_guardsize_set): Add
prototype.

* threadproc/unix/thread.c (apr_threadattr_guardsize_set): Add
function.

* threadproc/os2/thread.c, threadproc/win32/thread.c,
threadproc/beos/thread.c, threadproc/netware/thread.c
(apr_threadattr_guardsize_set): Add ENOTIMPL stubs.
