63b1eb104f Improve 64-bit cleanliness: make sure to use long format specifiers for
long arguments. This is WARNS=2 clean now.

2ef41c0cb5 Reserved one of the spare fields in struct gmon to record the history
counter type, as threatened in rev.1.8 (the density doesn't need to
be recorded since it can be derived from other fields).  This doesn't
affect binary compatibility, but new utilities won't be able to depend
on the contents of this field because libc/gmon/gmon.c was broken --
it wrote garbage to the spare fields.

Added a history counter type field to struct gmonparam.  This breaks
binary compatibility a little, since kgmon wanted to read the whole
struct.  Fixed kgmon to only depend on reading the critical earlier
parts of the struct.  This should also fix 6+ year old breakage of
binary compatibility when the profrate field was added.

Only initialize the new field in struct gmon for now, so that the
compatibility code for this (in kgmon) gets tested.  The compatibility
code has to guesstimate the value.  The new field in struct gmonparam
is for the kernel to initialize so that kgmon doesn't have to guess.

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.

4be4929c2b Get rid of _PATH_UNIX completely; use getbootfile(3) instead.
DANGER WILL ROBINSON!
_PATH_UNIX is currently defined as the literal string "don't use this".
I am of two minds about this myself, but wanted to get something into the
tree as quickly as possible.
