Simplify the PCI bus dma tag code a bit. First, don't create a tag at
all for platforms that only have 32-bit bus addresses. Second, remove
the 'tag_valid' flag from the softc. Instead, if we don't create a
tag in pci_attach_common(), just cache the value of our parent's tag
so that we always have a valid tag to return.

Improve multi-line kernel ident parsing
Instead of blindly grabbing the line with 'Version string' and the
following one from the core info file, take all lines after 'Version
string' until the one one that matches the field format in the core info
file. This provides compatibility with VendorBSD modifications that have
a different kernel ident format.

At the risk of reducing source compatibility with old NetBSD and Sprite:
o) Get rid of some unused macros related to features we don't intend to
provide.
o) Get rid of macro definitions for MIPS-I CPUs. We are not likely to
support anything that predartes MIPS-III.
o) Respell MIPS3_* macros as MIPS_*, which is how most of them were being
used already.
o) Eliminate a duplicate and mostly-unused set of exception vector macros.
There's still considerable duplication and lots more obsolete in our headers,
but this reduces one of the larger files to a size where one could reckon
about the correctness of its contents with a mere few hours of contemplation.
There is, of course, a question of whether we need definitions for fields,
registers and configurations that we are unlikely to ever use or implement,
even if they're not obsolete since 1991. FreeBSD is not a processor
reference manual, and things that aren't used may be wrong, or may be
duplicated because nobody could possibly actually know whether they're
already defined.
Provide wbwd(4), a driver for the watchdog timer found on various
Winbond Super I/O chips.
With minor efforts it should be possible the extend the driver to support
further chips/revisions available from Winbond. In the simplest case
only new IDs need to be added, while different chipsets might require
their own function to enter extended function mode, etc.

Store TLS base in the sigframe just as is done in freebsd32_sendsig. Because
the native sigreturn doesn't use set_mcontext like the COMPAT_FREEBSD32 version
does, this wouldn't actually result in overwriting the TLS base. Probably it
makes sense to restructure the native sigreturn to use set_mcontext for
consistency, and to allow sigreturn to change the TLS base.

Fix two and a half oversights in COMPAT_FREEBSD32 related to contexts and
TLS:
o) The mc_tls field used to store the TLS base when doing context gets and
restores was left a pointer and not converted to a 32-bit integer. This
had the bug of not correctly capturing the TLS value desired by the user,
and the extra nastiness of making the structure the wrong size.
o) The mc_tls field was not being saved by sendsig. As a result, the TLS base
would always be set to NULL when restoring from a signal handler.
Thanks to gonzo for helping track down a bunch of other TLS bugs that came out
of tracking these down.
