mdoc: order prologue macros consistently by Dd/Dt/Os
Although groff_mdoc(7) gives another impression, this is the ordering most widely used and also required by mdocml/mandoc.

Our implementation of granpt(3) could be valid in the future.
When I wrote the pseudo-terminal driver for the MPSAFE TTY code, Robert Watson and I agreed the best way to implement this, would be to let posix_openpt() create a pseudo-terminal with proper permissions in place and let grantpt() and unlockpt() be no-ops.
This isn't valid behaviour when looking at the spec. Because I thought it was an elegant solution, I filed a bug report at the Austin Group about this. In their last teleconference, they agreed on this subject. This means that future revisions of POSIX may allow grantpt() and unlockpt() to be no-ops if an open() on /dev/ptmx (if the implementation has such a device) and posix_openpt() already do the right thing.
I'd rather put this in the manpage, because simply mentioning we don't comply to any standard makes it look worse than it is. Right now we don't, but at least we took care of it.

Clean out some empty mergeinfo records, presumably by people doing local cp/mv operations. The full repo-relative URL should be specified for the source in these cases.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system.
The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following:
- Improved driver model:
The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers.
If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver.
- Improved hotplugging:
With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc).
The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly.
- Improved performance:
One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters.
Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Implement POSIX grantpt(3) functionality, and add a pt_chown utility (akin to Solaris, it is in /usr/libexec) to perform the handing over of tty nodes to the user being granted the pty.
