| * | add posix_spawn [f]chdir file actions•••these are presently extensions, thus named with _np to match glibc and
other implementations that provide them; however they are likely to be
standardized in the future without the _np suffix as a result of
Austin Group issue 1208. if so, both names will be kept as aliases.

| * | rework mechanism for posix_spawnp calling posix_spawn•••previously, a common __posix_spawnx backend was used that accepted an
additional argument for the execve variant to call in the child. this
moderately bloated up the posix_spawn function, shuffling arguments
between stack and/or registers to call a 7-argument function from a
6-argument one.
instead, tuck the exec function pointer in an unused part of the
(large) pthread_spawnattr_t structure, and have posix_spawnp duplicate
the attributes and fill in a pointer to __execvpe. the net code size
change is minimal, but the weight is shifted to the "heavier" function
which already pulls in more dependencies.
as a bonus, we get rid of an external symbol (__posix_spawnx) that had
no really good place for a declaration because it shouldn't have
existed to begin with.

| * | add no-op POSIX_SPAWN_USEVFORK to spawn.h•••the bit is reserved anyway for ABI-compat reasons; this documents it
and makes it so we can have posix_spawnattr_setflags check for flag
validity without hard-coding an anonymous bit value.

| * | implement new posix_spawn flag POSIX_SPAWN_SETSID•••this functionality has been adopted for inclusion in the next issue of
POSIX as the result of Austin Group issue #1044.
based on patch by Daurnimator.

| * | fix some restrict-qualifier mismatches in newly added interfaces•••these should have little/no practical impact but they're needed for
strict conformance.

| * | add support for thread scheduling (POSIX TPS option)•••linux's sched_* syscalls actually implement the TPS (thread
scheduling) functionality, not the PS (process scheduling)
functionality which the sched_* functions are supposed to have.
omitting support for the PS option (and having the sched_* interfaces
fail with ENOSYS rather than omitting them, since some broken software
assumes they exist) seems to be the only conforming way to do this on
linux.

| * | remove all remaining redundant __restrict/__inline/_Noreturn defs | Rich Felker | 2012-09-08 | 1 | -5/+1 |
| * | use restrict everywhere it's required by c99 and/or posix 2008•••to deal with the fact that the public headers may be used with pre-c99
compilers, __restrict is used in place of restrict, and defined
appropriately for any supported compiler. we also avoid the form
[restrict] since older versions of gcc rejected it due to a bug in the
original c99 standard, and instead use the form *restrict.

| * | fix various errors in function signatures/prototypes found by nsz | Rich Felker | 2011-09-13 | 1 | -2/+2 |
| * | initial implementation of posix_spawn•••file actions are not yet implemented, but everything else should be
mostly complete and roughly correct.
