Mention nasty interactions between new FFS superblock layout and old
fsck_ffs, using a heavily-abridged version of fvdl's original announcement.
Remove extra \n's in boot message.
PR/2845: Mike Schwartz: Allow some #defines to be tuned by kernel options
by protecting them via #ifndef OPTIONNAME
Improved bahvior for map_fd. When Darin uses findspace = 0, this seems to
request a mapping at fixed address, overlaying previously existing mappings.

The overlay is done by unmapping (sys_munmap) before mapping at fixed
location. This makes XDarwin able to link and run.

PR/17738: Matthias Drochner, PR/21230: Onno van der Linden: vt100 wscons
crashes restoring cursor. Fixed by adding a flag as suggested.
The sysctl returning the amount of memory in the system returns "int",
which is silly.  Luckily, it really does return the correct result if
interpreted as an unsigned int.  This change lets dump work on 32-bit
systems that have more than 2GB of RAM.
PR/21236: Simon Hitzemann: Fix missing space in error format. While I am
there make a single copy of the error string instead of 6 and share it.
PR/3046: Chris G. Demetriou: ldd actually runs target programs.
This is the case only with a.out programs, and the manual page has been
changed to reflect that in the BUGS section. Since most our architectures
have been converted to elf, this is not an issue anymore.
