Re-instate UMA cached backend for 4K - 64K allocations.  New consumers
like geli(4) uses malloc(9) to allocate temporary buffers that gets
free'ed shortly, causing frequent TLB shootdown as observed in hwpmc
supported flame graph.

Discussed with:	jeff, alfred
MFC after:	1 week
Add a new loader tunable, vm.kmem_zmax which allows a system administrator
to limit the maximum allocation size that malloc(9) would consider using
the UMA cache allocator as backend.

Renamed hw.ixgbe.unsupported_sfp -> hw.ix.unsupported_sfp

This now matches all other ixgbe sysctl / tunables.

Fix euro symbol in copied keymaps

These were copied from share/syscons/keymaps/??.iso.kbd.  They were
not actually ISO 8859-1 as assumed.  When interpreted as Unicode they
ended up with the generic currency sign (U+00A4) instead of the euro
(U+20AC).

Added 4K quirks for Corsair Force GT and Samsung 840 SSDs

Skip pgrep-j and pkill-j if jail or jls is not installed.

Even though jail is part of the base system, it can be disabled by src.conf
settings. Therefore, it should be listed as a required program for tests
that use it.

Streamline format extensions. Either the compiler supports them, and
we enable them and format wordings. Or it doesn't, and we disable
format warnings because the kernel uses the extensions pervasively.
Delete pp_isadma. It isn't use, and the code that used it has been
commented out (temporarily) since 1998 when this driver hit the
tree. Also, no need to compute the ethernet header and then never use
it.
Disable all inline warnings on gcc >= 4.3. Not sure exactly where the
cutover is, but we need better tools to cope with inline tuning per
compiler version than we have. This is a quick bandaid until such
tools are around.
ins is only set and unused, but only when we're not doing software
single stepping. Only set it when we're doing that by bending
style(9) rules a little to avoid even worse #ifdef soup.
Only install the boot loader if it actually exists. This is a stop-gap
change, since larger changes to use geom more exclusively to create
partitions is in th works.
create_$ARCH_diskimage never really took off. Collapse back down to
just one.
