- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Start to convert this over to the new tty layer. These changes allow
this driver to compile and limp along with the new layer. These changes
do not deal with proper locking around access to the HW. This is only
a starting point. I have not tested modem control but tip seems to work
okay and I can send and receive characters which I needed for one of my
-current boxes. I have not tied this driver back up to the build since
I don't want people to think it is ready for prime time. If anyone
else has some cycles to work on this feel free to!

Also add support for a 16 port PCI interface I have at work.

- Make rp(4) 64-bit- and endian-clean as well as work on strict alignment
archs. [1]
- Instead of bus_space_{read,write}*(rman_get_bustag(), rman_get_bushandle())
use bus_{read,write}*() for efficiency.

Prevent the rp driver from panic'ing on first access and make at
least the pci device unloadable

- Use ttymalloc() rather than a plain malloc to allocate the
rp->rp_tty ttys. This is now required due to the recent locking
changes to ttys and prevents a panic due to locking an unitialized
t_mtx.

- Allow the pci driver to be unloaded. This involved moving
the call rp_releaseresource() to the end of rp_pcireleaseresource(),
since rp_pcireleaseresource() uses ctlp->dev, which is freed
by rp_releaseresource().

- Allow the generic part of the driver to be unattached by providing
a hook to cancel timeouts.

Do the dreaded s/dev_t/struct cdev */
Bump __FreeBSD_version accordingly.

1. Update Comtrol RocketPort driver(rp) to version 3.02.
2. Newbusify the driver.
3. Build as a module.

4. Use correct minor numbers when creating device files.
5. Correctly lock control characters.
6. Return ENXIO when device not configured.

7. Fix the baud_table.

Note:
- the old driver still lives in src/sys/i386/isa, so that you can
revert to it if something goes wrong.
- The module does not detach very well. Attaching works fine.
