8abdc2eb40 Sweep through the tree fixing mmap() usage:
- Use MAP_FAILED instead of the constant -1 to indicate
    failure (required by POSIX).
  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.

d7b025c3ae Tidy up the generated config.c file. Use #include "opt_config.h", comment
out text after #endif line, add missing \n at end of file, only install new
config.c if it's different to the last one which preserves the timestamp.

5bd7b80934 Part #2 of the config cleanup. More aggressive, replaced an NIH
version of strdup() by a macro, killed many calls to strdup(), thus
potentially wasting less malloc'ed space (their args were never be
free()ed desptie despite of being malloc'ed).  Probably still a huge
memory leak at all...  Also killed two totally useless variables.

I've tested it as i could, but wouldn't be surprised if unexpected
problems showed up.  So watch out this space!

912e603778 Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches.  The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes.  Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header.  This
hack will do until then.  (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'.  `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.

6d41b96fd7 Implement support for conf/options and i386/conf/options.i386
Note that this code is dormant unless the options files exist.
Also, parsing of quoted options in the config files is improved.

What this allows, is all the options in LINT to be specified to be
configured as #defines in a file rather than on the CC command line at
kernel build time.  This means that 'make depend' will catch dependencies
on actual *options*, meaning that you can run 'config' and 'make depend'
in complete safety WITHOUT removing the compile directory each time.

Unfortunately, this requires a pass over the source to get the individual
files to #include the new .h files that would be generated by config.
This has a small compile time penalty (appears up to about 2% slower)
from a "fresh" build.  Of course, you should not be needing to do complete
rebuilds very often once this was completed, so it would be an overall
win for most people.

Since this code is dormant and we've got a lot of other things happening
on the kernel tree at the moment (prototypes, devfs, static declarations
etc) I am not planning on doing any changes to activate this feature just
yet.

babb4e927f Add a new `conflicts' flag for telling when a device is in conflict with
others.  The flag can be put in descriptive locations, e.g.:

device sb0      at isa? port 0x220 irq 7 conflicts drq 1 vector sbintr
or
device psm0	at isa? port "IO_KBD" conflicts tty irq 12 vector psmintr

But is nonetheless boolean only.  You can't turn conflict checking off for
only a given type of conflict.  I didn't deem it worth the trouble at this
stage, and it's far better than the ALLOW_CONFLICT_* that preceeded it.

188291d20f Do away with 'options SWAP_GENERIC' once and for all: I get ill
just thinking about it.

Two changes need to be made to allow 'config kernel swap generic' to
work properly without requiring any compile-time flags:

/usr/src/usr.sbin/config/mkswapconf.c: we need to define a dummy stub
for the setconf() function to replace the one in swapgeneric.c that
isn't available in non-generic configurations.

/usr/src/sys/i386/i386/autoconf.c: the -a boot flag causes setroot()
to be skipped and lets setconf() prompt the user for a root device.
If you skip setroot() in a non-generic kernel, you could get severely
hosed. To avoid this, we silently ignore the -a flag if rootdev != NODEV.
(rootdev is always initialized to NODEV in swapgeneric.c, so if
we find that rootdev is something other than NODEV, we know we're
not using a generic configuration.)

80785c507b Add new keywords to config. The options availible in file.i386 are now:
/*
         * filename     [ standard | optional ] [ config-dependent ]
         *      [ dev* | profiling-routine ] [ device-driver] [ no-obj ]
         *      [ compile-with "compile rule" [no-implicit-rule] ]
         *                     [ dependancy "dependancy-list"]
         */

I added

no-obj -  This entry does not create anything linkable to the kernel.
dependancy - Add additional dependancy rules to a target.
no-implicit-rule - Don't assume .c -> .o type rules.  Config is really
             dumb in this area and assumes that everything is a .c file
	     irregarless of extention.  This was the best choice really
	     since there may even be .c file that you don't want to follow
	     the standard rules.

This was all done so that the building to the aic7770 assembler and using
the aic7770 assembler in the building of the aic7770 driver could be config
dependant.  I can now have an entry like this for the driver:

aic7770                         optional        ahc     device-driver   \
        compile-with    "${CC} $> -o $@"                                \
        dependancy      "$S/gnu/misc/aic7770/aic7770.c"                 \
        no-obj no-implicit-rule
aic7770_seq.h                   optional        ahc     device-driver          \
        compile-with "${.CURDIR}/aic7770 -o $@ $S/gnu/misc/aic7770/aic7770.seq"\
        dependancy "$S/gnu/misc/aic7770/aic7770.seq aic7770"                   \
        no-obj no-implicit-rule
i386/isa/aic7770.c              optional        ahc     device-driver   \
        dependancy "aic7770_seq.h"

I also added '\' escaping to newlines so that this doesn't look as gross as
it could have.
