Modify MIPS page table entry (PTE) initialisation so that cachability
bits are set only once, using is_cacheable_mem() to determine what
caching properties are required, rather than also unconditionally
setting PTE_C_CACHE in init_pte_prot(). As PTE_C_CACHE |
PTE_C_UNCACHED == PTE_C_CACHE, this meant that all userspace memory
mappings of device memory (incorrectly) used caching TLB entries.
This is arguably not quite what we want, even though it is (more)
consistent with the MIPS pmap design: PTE caching properties should
be derived from machine-independent page table attributes, but this
is a substantially more complex change as the MIPS pmap doesn't yet
know about page attributes, causing it to ignore requests by device
drivers that want uncached userspace memory mappings as they
describe memory-mapped FIFOs or shared memory with a device not
participating in the cache coherence scheme.
This fixes cacheability issues (specifically, undesired and
unrequested caching) seen in userspace memory mappings of Avalon SoC
bus device memory on BERI MIPS.

The existing method for testing for MRR is to call the "SetupXTXDesc"
HAL method and see if it returns AH_TRUE or AH_FALSE. This capability
explicitly lists what number of multi-rate attempts are possible.
"1" means "one rate attempt supported".
all diskN aliases for providers (which more or less corresponds to how the
x86 version behaves) but instead probe only those listed in the boot-device
OFW environment variable. This has the following advantages:
- avoids otherwise unavoidable OFW warnings about failures to open disks
for which aliases exist but no actual hardware is connected
- avoids issues due to different diskN naming schemes
- aligns us with Solaris

* shuffle things around so things fall on natural padding boundaries;
* add a couple of new flags to specify LDPC and whether to switch to the
low power RX chain configuration after this TX has completed.

Specifically, however:
* AR9280 and later support 1-stream STBC RX;
* AR9280 and AR9287 support 1-stream STBC TX.
The STBC support isn't announced (yet) via net80211 and it isn't at all
chosen by the rate control code, so there's no real consumer of this
yet.

(future) TPC support in the AR9300 HAL.
This is effectively a no-op for the moment as (a) TPC isn't really
supported, (b) the AR9300 HAL isn't yet public, and (c) the existing
HAL code doesn't use these fields.

of buffers, only the number of descriptors.
This involves:
* Change the allocation function to not use nbuf at all;
* When calling it, pass in "nbuf * ndesc" to correctly update how many
descriptors are being allocated.
Whilst here, fix the descriptor allocation code to correctly allocate
a larger buffer size if the Merlin 4KB WAR is required. It overallocates
descriptors when allocating a block that doesn't ever have a 4KB boundary
being crossed, but that can be fixed at a later stage.

VALE lets you dynamically instantiate multiple software bridges
that talk the netmap API (and are *extremely* fast), so you can test
netmap applications without the need for high end hardware.
This is particularly useful as I am completing a netmap-aware
version of ipfw, and VALE provides an excellent testing platform.
Also, I also have netmap backends for qemu mostly ready for commit
to the port, and this too will let you interconnect virtual machines
at high speed without fiddling with bridges, tap or other slow solutions.
The API for applications is unchanged, so you can use the code
in tools/tools/netmap (which i will update soon) on the VALE ports.
This commit also syncs the code with the one in my internal repository,
so you will see some conditional code for other platforms.
The code should run mostly unmodified on stable/9 so people interested
in trying it can just copy sys/dev/netmap/ and sys/net/netmap*.h

private data.
We can set/get private data with the documented el_get() and
el_set() so there's no need for our local extensions, which
never received much use anyway.
While here, also re-arrange the call to term_init_arrow. This
was left over from r89735 but is not required anymore.
This changes reduce differences against NetBSD's libedit.

Remove duplicate JABLOTRON PC60B entry.
Note that some of the devices added here are multi-port devices. The
uslcom(4) driver currently only supports the first port on such devices.
Update the man page to reflect the full list of supported devices.
Remove two caveats from the CAVEATS section, as both listed caveats no
longer apply. Add a caveat about multi-port devices.
