move flashrdbuilder to its own directory
Update growimg to use flashrd framework, solves various problems by using umountwait and also provides better fallback control to clean up mounts, vnds if something goes wrong.
move this stuff to builder/
get rid of some uppercase and always perform pwd_mkdb on upgrade
(this will be nice for the time_t bump anyways)
william-os4y contributed keyboard encoding support for cfgflashrd in

version 1.4
Stop trying to redefine NKL2_KIMG_ENTRIES on amd64 for now.
OpenBSD 5.4 and later define this to 16 automatically, which is fine
for our needs. It requires a source code patch to make this
'optionable' in the kernel config, so stop trying.
start using the local system installboot, not the destination system's
copy. this makes it possible to build a system version on one
end of the time_t jump while your host system is on the other end.

before we assumed that there was always going to be new magic in the
installboot which might be useful. now we assume there is new evil.
perhaps the shift back to assuming magic will resume in the future.
for now make life easier with the current situation as it is.
get rid of annoying message in certian case
properly escape the new text
Fixed hostname from flash path error
Delete obsolete builder script
