Add an internal _once() method. This works identical to pthread_once(3) with the additional property that it is safe for routines in libc to use in both single-threaded and multi-threaded processes. Multi-threaded processes use the pthread_once() implementation from the threading library while single-threaded processes use a simplified "stub" version internal to libc.

MFC: Change the ABI of some of the structures used by the SYSV IPC API:

2009-07-31T20:32:55Z

- Various members of struct ipc_perm use appropriate types instead of unsigned short. - The shm_segsz member of struct shmid_ds is now a size_t instead of an int which should allow for complete support of SYSV SHM regions >= 2GB. - The shm_nattch member of struct shmid_ds is now an int instead of a short. - The existing versions of the __semctl(), msgctl(), and shmctl() system calls have been renamed to freebsd7_*() and implement the old ABI. New versions of these system calls provide the new ABI. The new system calls also use newer symbol versions in libc so old and new binaries will both work under new kernels. - Specific to 7.x: the kern_msgctl(), kern_semctl(), and kern_shmctl() functions now use ABI shims that transparently "rename" the functions to kern_new_*() for all new modules. Existing compat functions under the old names remain to provide compatibility for older kernel modules.

from HEAD. Since libkse is still built on RELENG_7, pthread_cleanup_push/pop are left as the functions, but the support code in libthr is present for the macro versions. Malloc in RELENG_7 does not require thread exit hook, but I decided to add empty handler for it, instead of removing callback from thr_exit(). No mergeinfo since this change is prepared by patching libthr and then bringing in required missed bits.

Update our resolver to BIND 9.4.3. Merge the resolver part of BIND 9.4.3 into HEAD. It includes the following fix: 2426. [bug] libbind: inet_net_pton() can sometimes return the wrong value if excessively large netmasks are supplied. [RT #18512] Reported by: Maksymilian Arciemowicz Approved by: re (kib)

call the pad-less versions of the corresponding syscalls if the running kernel supports it. Check kern.osreldate once per program and cache the result to select the appropriate syscall. This maintains userland compatability with kernel.old's from quite a while back. Approved by: re (kensmith)
