Export the guard size of the main thread via vm.guard_size. Add a
complementary writable sysctl for the initial guard size of threads
created via pthread_create. Let the existing attribut accessors do the
right thing. Raise the default guard size for threads to 64KB.

libpthread_dbg(3) deletion from the base distribution

libpthread_dbg(3) is a remnant library from the M:N thread model
(pre-NetBSD-5.0) API to introspect threads within a process and for use
of debuggers.

Currently in the 1:1 model it's not used in GDB neither in LLDB and it's
not either planned to be used. It's current function to read pthread_t
structures is realizable within a regular debugger capable to
instrospect objects within a tracee (GDB, LLDB...).

Remaining users of this API can still use this library from
pkgsrc/devel/libpthread_dbg.

ld.elf_so is reentrant.

As per (now closed) PR lib/43581, add a note about unsupported modifications
to the red zone size.

Fix typo.

We've got the priority/class stuff now.

Update.

Mutexes:

- Play scrooge again and chop more cycles off acquire/release.
- Spin while the lock holder is running on another CPU (adaptive mutexes).
- Do non-atomic release.

Mutexes:

- Play scrooge again and chop more cycles off acquire/release.
- Spin while the lock holder is running on another CPU (adaptive mutexes).
- Do non-atomic release.

Threadreg:

- Add the necessary hooks to use a thread register.
- Add the code for i386, using %gs.
- Leave i386 code disabled until xen and COMPAT_NETBSD32 have the changes.

Update.

Update.

Remove the PTHREAD_SA option. If M:N threads is reimplemented it's
better off done with a seperate library.

Don't grab the state lock to check for cancellation around condition
variables, as _lwp_wakeup/lwp_park provide the necessary barrier.

fix a race between pthread_exit and pthread_create.
inefficient, but better than crashing.

Add some items for 1:1 threads.

Update list of items.

pthread_kill() was implemented, remove from list
pthread_cond_timedwait() now works even before SA initialization, but some
other routines do not; update the paragraph for this

Merge the nathanw_sa branch.
