- switch to perl for better data structures and (thus) speed
- fix a couple glitches in the interpretation of the stabs output
- compress the strings by putting them in one big array and overlaying
suffixes
- all sizes and offsets are <64k, so use u_short for them
This results in ~60% reduction in the resulting text size and it now
takes less than a second to create on fast platforms.

using the -MD option to cc, with -MP, -MT, and -MF where needed, converting
"make depend" to a no-op. This increases parallelism for those using "make -j"
and keeps the dependencies up to date with each compilation automatically.
sparc and vax users will need to rebuild gcc with support for the
-M[PTF] options before config'ing with this diff.

early MD and late MI files must be split up so that vers.o can sneak
between. Issue spotted by bluhm, repair discussed with miod

having it linked last is bad (on at least i386 and amd64) because the lapic
is mapped over the start of the data segment -- savecore(8) then reads the
version string for a fixed buffer space, and reads into the lapic area
causing unintended side-effects (at least on Intel X5570 and X5680)

the differences between these files. You will need a newer config(8) binary
to be able to build kernels.
ok kettenis miod

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.
The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.
This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on. You can still screwed really easily, so continue running make
depend as config tells you.

two directories. in reality, because of how we place files, it has four:
.../arch/A, .../arch/A/A, .../arch/M, and .../arch/M/M
formalize this A/A and M/M scheme directly in the Makefiles, which makes
them a lot more similar

What happened was that the output of mkdep was fed to a sed expression
that trimmed a bit more than required and also failed to work when
attempting to do make depend with pcc.
Example:
genassym_c.o: /tmp/genassym.whatever ../../../../../sys/param.h \
was changed to:
assym.h: \
but what was intended was:
assym.h: ../../../../../sys/param.h \
For the pcc -M output things were a bit different and after the make
depend the genassym entry would still remain and make would fail. This
affected all platforms except amd64 and sgi.
Okay miod@.

directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.
There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.
Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

(with symbols) to bsd.gdb, then strips bsd. This diff makes it rename the
file with symbols, and then asks strip to output the stripped version as
bsd. Avoids a potentially lengthy wait when we would otherwise copy the
large (50MB+) kernel with debug symbols.
