Change pthread_cleanup_{push,pop} to macros that store the cleanup info
on the stack instead of mallocing the list and move the APIs from libpthread
to libc so that they can be used inside libc.
Note: the standard was explicitly written to permit/support this
"macro with unmatched brace" style and it's what basically everyone
else already does. We xor the info with random cookies with a
random magic to detect/trip-up overwrites.
Major bump to both libc and libpthread due to the API move.

Use a Thread Information Block in both single and multi-threaded programs. This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via <errno.h> now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

Split the intra-thread functionality from kill(2) into its own syscall thrkill(2), rolling the kill(2) syscall number with the ABI change to avoid breaking binaries during during the transition. thrkill(2) includes a 'tcb' argument that eliminates the need for locking in pthread_kill() and simplifies pthread_cancel(). Switch __stack_smash_handler() to use thrkill(2) and explicitly unblock SIGABRT. Minor bump to both libc and libpthread: make sure you install a new kernel! ok semarie@

Merge the sigaction() and sigprocmask() overloads/wrappers from libpthread into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@

Switch time_t, ino_t, clock_t, and struct kevent's ident and data members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

A couple small but long anticipated changes:
- Link libpthread.so with -znodlopen. Because libpthread overrides
the weak symbols in libc, we can't allow it to be dynamically
loaded or else libc's weak symbols might have already been
resolved by ld.so. (Also, major bump because this is technically
a backwards incompat change in behavior, although dlopen()ing
libpthread never really worked.)
- Link libc.so with -nodefaultlibs -lgcc. This ensures that libc
doesn't try to link against itself (which ld.so wouldn't like).
- Change GCC 4 to link shared objects with -lpthread and -lc as
appropriate, now that there's no issues with doing so. This means
that it's no longer necessary to patch software to use -pthread
instead of -lpthread. (Ports tree rejoice!)
Also, to preemptively answer this question: No, this does not
eliminate the need for LD_PRELOAD=libpthread.so. That's a separate
issue that won't be resolved until we eliminate libc's weak symbols.
Discussed extensively on email and icb over the past few months.

__tfork() needs to set the stack address of the new thread in the kernel, so that it can't get a signal while still running on the parent thread's stack. Also, pass in sizeof(struct __tfork) to provide forward compat when more members are added. This is an ABI change, so switch syscall numbers and bump lib majors this time. ok deraadt@ matthew@

Reimplement mutexes, condvars, and rwlocks to eliminate bugs,
particularly the "consume the signal you just sent" hang, and putting
the wait queues in userspace.
Do cancellation handling in pthread_cond_*wait(), pthread_join(),
and sem_wait().
Add __ prefix to thr{sleep,wakeup,exit,sigdivert}() syscalls; add
'abort" argument to thrsleep to close cancellation race; make
thr{sleep,wakeup} return errno values via *retval to avoid touching
userspace errno.
