0b5c2a058c Kernel: use okendpt() to resolve stored endpoints 
This adds an integrity check at very little cost, and should stop
Coverity from flagging array overruns on the result.

cf9a4ec79b Kernel: clean up include statements a bit 
Coverity was flagging a recursive include between kernel.h and
cpulocals.h. As cpulocals.h also included proc.h, we can move that
include statement into kernel.h, and clean up the source files'
include statements accordingly.

31d8526346 libexec: add load_offset feature, used for ld.so 
. ld.so is linked at 0 but it can relocate itself; we
	  wish to load ld.so higher though to trap NULL dereferences.
	  if we know we have to execute ld.so, vfs tells libexec to put it
	  higher.

ad898517ac sprofdiff for comparing sprofile results 
This patch adds the sprofdiff tool, which compares two sets of profiling
output files. It sorts processes and symbols by difference in average
number of samples, placing those that took more time on the left first
and those that took more time on the right last. If multiple runs are
combined, a standard deviation is computed and this is used to compute
the significance level, which gives an indication of which differences
are likely to be due to chance.

This tool is run not on the raw profiling files, but on the output of
sprofalyze -d (a new option). Though having to use two tools and an
intermediate file seems a bit awkward, the advantage is that the
original source tree is not needed to resolve the symbols. For
comparisons, this is very useful. Also, the intermediate file is in a
text format that can easily be processed by scripts, which may be useful
for other purposes as well.

b3f47f5835 vm: ignore RS pin (pre-allocate) requests for now 
. done by RS to reduce/remove dependency on VM for recovery
	. RS has the default stack size of 64MB since the nosegments
	  change, using a huge amount of unused memory to pre-allocate
	. ignore these requests until actually required (i.e. being able
	  to survive VM crashes)

Thanks to pikpik for investigating why RS was so huge.
