sar2pcp man page - correct NAME entry

Was collectl2pcp (!) ... which caused an installation failure on FreeBSD
(don't even ask).
qa/359 - more cgroups filtering required
qa/022 - dodge newlines in proc metric instance names

Come from our own awk scripts in QA!
qa/src/GNUlocaldefs - pmlogger and pmlogextract don't need special pathnames

Now binaries are in /usr/bin.
qa/admin/check-vm - check $HOME is searchable by others

Needed for some QA tests so user pcp (aka pmcd) can find QA
PMDAs.
qa/admin/pcp-daily - don't need make clean all the time
qa/admin/pcp-qa-summary - tweak output formatting
qa/admin/show-me-all - map N -> 00N and NN -> 0NN (like show-me)
