Retire BCM53XX_CONSOLE_EARLY in favour of EARLYCONS

UFS/LFS dirhash:
- Enable UFS_DIRHASH if the architecture or kernel model specific config
file can use 128MB of RAM or more.
- Remove experimental tag from UFS_DIRHASH; it's been with RUMP kernel
and by a number of NetBSD developers for years.
- Add LFS_DIRHASH if LFS was enabled.
- Be somewhat consistent with FS options order.

Collapse all CPU_CORTEXA<n> options into CPU_CORTEX and do runtime
detection instead of ifdefs where required.

remove the 'wd* at umass?' for the non-standardized and rare (extinct?)
In-System Design ATA protocol over Bulk-Only devices from most kernels,
leave only in i386/amd64 ALL; it's unmaintained and likely currently broken,
lack of test hardware makes it impossible to support

Remove "options IPKDB", and the other associated options, from the config
files.

ipkdb is being retired. Its code is really old, and hasn't kept pace with
today's expectations: IPv6, SMP, modern NICs. The associated code for x86
was already removed because it was too incorrect to stay.

There are plans to rewrite a similar feature from scratch.

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

Rename ARM A9 Global Timer driver name to support fdt.

- Rename a9tmr to arma9tmr.
- Add a9tmr_fdt.c based gtmr_fdt.c.

clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

Remove TCP_COMPAT_42 from the config files. Pass 3.

Add a heading to describe the class of device axe(4) is.

ALL on amd64 and i386.

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

- Enable Wedge support for MBR/BSDLABEL where it was commented out.
- Add apple partition support where it was missing
- Add comments where missing

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

Add "options COMPAT_70" to all kernel configuration files that
already had "options COMPAT_60".

Add COMPAT_NETBSD32, following the switch to eabi by default.
