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.

PMAP_DEBUG has been deleted on arm

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.

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.

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.

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".

Remove obsolete SysV semaphores limit options (SEMMNI, SEMMNS, and SEMUME).

WABPL is no longer considered experimental (has not been for some time)

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

dependant -> dependent

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
