sysinst fails with "floating exception" after
changing MBR partition size in MBR editor menu
if the target disk doesn't have valid MBR partition
or has a valid partition 0 whose offset is not 1MB aligned
(like 63 sectors).
read_mbr() (which calls get_ptn_alignment()) is called
before set_bios_geom(), so bhead is not initialized there
and ptn_alignment could be zero.
To workaround, explicitly call get_ptn_alignment() again
in edit_mbr() to update ptn_alignemnt per BIOS geom values.
assertion failure (and thus a crash in DIAGNOSTIC kernels). Independently
discovered by YAMAMOTO Takashi and Joel Sing.
To avoid this, introduce a cpu_mcontext_validate() function and move all
sanity checks from cpu_setmcontext() there. Also untangle the netbsd32
compat mess slightly and add a cpu_mcontext32_validate() cousin there.
Add an exhaustive atf test case, based partly on code from Joel Sing.
Should finally fix the remaining open part of PR kern/43903.

MBR_BOOTCODE
optional MBR bootcode which should be installed by fdisk(8)
(default: empty)
- specified MBR_BOOTCODE must exist in ${DESTDIR}/usr/mdec
- if MBR_BOOTCODE is not specified,
MBR_DEFAULT_BOOTCODE (default: mbr) will be used
if the target ${MACHINE} has the one in /usr/mdec
INSTALLBOOTOPTIONS
options passed to installboot(8), e.g., -o console=com0
(default: empty)

Proposed by Brook Milligan on current-users@:
http://mail-index.NetBSD.org/current-users/2012/04/16/msg019892.html
Also make USE_MBR work on ${MACHINE}s which don't have the default
/usr/mdec/mbr bootcode. (no such port has the liveimage target yet though)
XXX: tools fdisk(8) implicitly uses host's /usr/mdec/mbr for the default
XXX: bootcode even for non-x86 targets if host is x86
Adjust various man pages and other documentation to point to capfile(5)
instead of termcap(5).
Remove getcap(3) as curses hasn't been building it for a long time.
Punt wrterm.c as tset no longer uses it.
