fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

255f31647e Fix resolving symbol names on ARM.
On ARM, binutils are adding '$a' symbols in the symbol table for
every function (in addition to normal symbol). When gprof(1) looks
up symbol name, it often reads '$a' instead of proper function name,
because it find it first. With this fix, when read symbol name
begins with '$' and previous symbol has the same address, it will
use previous symbol name (which is proper function name).

03ce187564 If running with "-K" really do not information about symbols from the a.out
argument.  Before this fix, after searching the currently-running kernel,
we would still search the a.out argument - completely override the in-kernel
list, essentially defeating the K flag's purpose.

762116ae25 Catch up with increasing the resolution suitable for high-res kernel
profiling from microseconds to nanoseconds in 1996.  Picoseconds are
already needed.

0b146898f0 Improve printing of self times in the flat profile for functions that
appear to be never called:

(1) If a function is never called according to its call count but it
    must have been called because its child time is nonzero, then print
    it in the flat profile.  Previously, if its call count was zero
    then we only printed it in the flat profile if its self time was
    nonzero.

(2) If a function has a zero call count but has a nonzero self or child
    time, then print its total self time in the self time per call
    column as a percentage of the total (self + child) time.  It is
    not possible to print the times per call in this case because the
    call count is zero.  Previously, this was handled by leaving both
    per-call columns blank.  The self time is printed in another column
    but there was no way to recover the total time.

(1) partially fixes the case of the "never called" function main() and
prepares for (2) to apply to main() and other functions.  Profiling
of main() was lost in the conversion from a.out to ELF, so main()'s
call count has always been zero for many years; then in the common
case where main() is a tiny function, it gets no profiling ticks, so
main() was completely lost in the flat profile.

(2) improves mainly cases like kernel threads.  Most kernel threads
appear to be never called because they are always started before
userland can run to turn on profiling.  As for main(), the fact that
they are called is not very interesting and their callers are
uninteresting, but their relative self time is interesting since they
are long-running.

Almost always printing percentages in the per-call columns would be
more useful than almost always printing 0.0ms.  0.1ms is now a long
time, so only very large functions take that long per call.  The accuracy
per call can approach 1-10 nsec provided programs are run for about
100000 times as long as is necessary to get this accuracy with high
resolution kernel profiling.

should be made a runtime option btw.
