sys/amd64/amd64/machdep.c:
The value reported by FreeBSD as "real memory" when booting
doesn't match what is later reported by sysctl as hw.realmem.
This is due to the fact that the value printed during the
boot process is fetched from smbios data (when possible),
and accounts for holes in physical memory. On the other
hand, the value of hw.realmem is unconditionally set to be
one larger than the highest page of the physical address
space.
Fix this by setting hw.realmem to the same value printed
during boot, this makes hw.realmem honour it's name and
account properly for physical memory present in the system.

- Move CAP_BINDAT and CAP_CONNECTAT rights to index 0 so we can include
CAP_LOOKUP right in them.
- Shuffle the bits around so there are no gaps. This is last chance to do
that as all moved rights are not used yet.

CAP_SYMLINKAT and CAP_UNLINKAT capability rights make no sense without
the CAP_LOOKUP right, so include this rights.

VM subsystem twice for every written record.
Tests on 24-core system show double reduction of CPU time spent on copying
single large well-compressed file.
This patch is not really needed on illumos (while not harm either) since
their memory allocator by default uses caching for all requests up to 128K.

Debuggers may need to change PSL_RF. Note that tf_eflags is already stored
in the signal context during signal handling and PSL_RF previously could be
modified via sigreturn, so this change should not provide any new ability
to userspace.

This field needs to be (a) set, and (b) greater than the other timeouts
(passive, active, maxquiet, etc.) It also is in microseconds, not

I hope this will fix the scan hangs that people are seeing.

is no longer a valid option, so remove 'WITHOUT_JADETEX=yes'
from PBUILD_FLAGS.
While here, also remove 'WITHOUT_X11=yes', since it will
cause a dependency conflict by requiring both print/ghostscript9
and print/ghostscript9-nox11.
Switch to OPTIONSNG format (WITHOUT_* -> OPTIONS_UNSET='FOO'),
and unset the FOP option, which requires Java (although it is
disabled by default). Also unset the 'IGOR' option, since
textproc/igor is a validation tool, not necessarily a dependency
of the doc/ build itself.
While here, reduce the line length of PBUILD_FLAGS.

Add check for buflen overflow by comparing the buflen with both offset
