that we can flush the register stack prior to entering the kernel.
This avoids having dirty registers and saves us from having to
manually write them to the backing store from within the kernel.
In that respect, flushing the RSE is both functionally required as
well as performance optimal.
On average we had 18 dirty registers when getcontext(2) was called
from libthr. Since libthr does not switch back to a context created
by getcontext(2), not having dealt with the dirty registers was
harmless.

While here, remove an artificial dependency in Ovfork.S by performing
manual register renaming.

* Merge strchr(3) and strrchr(3) to strchr(3) since the two functions
are almost identical.
* Make the wording of index(3) and strchr(3) more similar.

don't probe the server at all for passwd.by* maps. This fixes
interoperability with the Services For UNIX NIS server (which is
really a front end to Captive^WActiveDirectory). This server
incorrectly returns success for all YPPROC_MASTER requests,
even for maps that don't exist, which makes it impossible to
(ab)use it to probe for the existence of the master.passwd.by*
maps.
This is a little kludgey, but basically restores the original
behavior of getpwent.c as it is in -stable, and works around both
the lack of YPPROC_ORDER on NIS+ servers as well as the broken
YPPROC_MASTER on Services For UNIX servers.

Remove the !hardway micro-optimisation from the CT_INT case to avoid

padding).

system by specifying the file system ID instead of a path. Use this
by default in umount(8). This avoids the need to perform any vnode
operations to look up the mount point, so it makes it possible to
unmount a file system whose root vnode cannot be looked up (e.g.
due to a dead NFS server, or a file system that has become detached
from the hierarchy because an underlying file system was unmounted).
It also provides an unambiguous way to specify which file system is
to be unmunted.
Since the ability to unmount using a path name is retained only for
compatibility, that case now just uses a simple string comparison
of the supplied path against f_mntonname of each mounted file system.

The old buffer was not being initialized and a later str*() op on
it would cause a crash if it wasn't initialized by a previous
call to setproctitle(3) with an actual string.

to clarify which system call accepts which arguments. Previously
the manual page gave the impression that calling unmount() with
flags of (MNT_FORCE | MNT_UPDATE | MNT_RDONLY) would downgrade a
read-write mount to read-only, which is clearly untrue; to do that,
these flags should be passed to mount() instead.
Change execvp to be a wrapper around execvP. This is necessary for some
of the /rescue pieces. It may also be more generally applicable as well.
