2018-08-20	remove erroneous SYMLINK_MAX definition from limits.h, pathconf	Rich Felker	-2/+1
	POSIX requires the symlink function to fail with ENAMETOOLONG if the link contents to be written exceed SYMLINK_MAX in length, but neither Linux nor our syscall wrapper code enforce this. the value 255 for SYMLINK_MAX is not meaningful and does not seem to have been motivated by anything except perhaps a wrong assumption that a definition was mandatory. it has been present (though moving through bits to top-level limits.h) since the beginning of the project history. [f]pathconf is entitled to return -1 as the limit for conf names for which there is no hard limit, with the usual POSIX note that an indefinite limit does not imply an infinite limit. in principle we might should report a limit for filesystems that impose one, but such functionality is not currently present for any of the pathconf limits, and adding it is beyond the scope of fixing the incorrect limit.

	Call SYS_exit on return from fn in __clone. This is the expected behavior of this function. Without this the child task will crash on return from fn, since it will return to nowhere.
2018-08-16	fix pthread_create return value with PTHREAD_EXPLICIT_SCHED	Rich Felker	-0/+1
	due to moved code, commit b8742f32602add243ee2ce74d804015463726899 inadvertently used the return value of __clone, rather than the return value of SYS_sched_setscheduler in the new thread, to check whether it needed to report failure. since a successful __clone returns the tid of the new thread, which is never zero, this caused pthread_create always to return with an invalid error number in the code path for PTHREAD_EXPLICIT_SCHED. this regression was not present in any releases.
