Remove some long dependant instruction sequences (ie allow parallel code).

Since 'rep stos' will have a long setup time, avoid doing it more than once.
For misaligned (start address or length) write an unaligned word at both
ends of the buffer then aligned 'rep stosd' the middle.
Use the same code for bzero().
bzero.S is left being compiled for a while (empty) - to avoid issues with
duplicate symbols in libc.a after update builds.

XXX: There are similar comment errors in some of the other string code.
XXX: We really need a regression test that includes misaligned memory
with searches designed to catch corner cases such as searching for 0,
-1, etc, and search length limit violations. Searching for 0 on
misaligned memory would have caught this problem.

Fix an issue introduced with the prop_stack change: It's not a good idea to
...
return a 3-value enum from a function declared to return bool. This broke
the recurse case for prop_object_equals(). Instead, declare the object type
equals routine to return a _prop_object_equals_rv_t.
Give the same treatment to the object type free routines: declare them to
return a _prop_object_free_rv_t, and consistently check those return values
againt the enum type.
Tidy up some whitespace while we're here.

acquiring the rwlock recursively in some paths.
Introduce _prop_rwlock_tryrdlock() and use it in these functions, so
that the rwlock is *always* acquired once, while here add some
_PROP_RWLOCK_OWNED asserts to verify.
This definitely fixes the "locking against myself" panics.

Do not acquire the rwlock recursively in prop_{array,dictionary}_iterator_reset()

when prop_{array,dictionary}_copyout_ioctl() is called.
Introduce _PROP_RWLOCK_OWNED() which is a KASSERT(rw_lock_held(lock))
and use it in those two functions, also acquire the rwlock in other
places where it is required now.
This fixes a LOCKDEBUG panic "locking against myself", as reported by
Geoff C. Wing in current-users@.
