perf tools: Fixup mmap event consumption (2013-10-28 16:06:00 -0300)

----------------------------------------------------------------
perf/urgent fixes:

. Add color overhead for stdio output buffer, which fixes
--stdio output being chopped up on the hot (red) entries,
fix from Jiri Olsa.

. Get 'perf record -g -a sleep 1' working again, removing the
need for -- separating perf options from the workload, restoring
ages old behaviour, fix from Jiri Olsa.
More patches allowing ~/.perfconfig setting up of default
callchain collecting method ("fp" or "dwarf") left for next
merge window.

. Fixup mmap event consumption, where we were acking the
consumption by writing the tail before actually accessing
the event, which could lead to using overwritten records
in things like 'perf record --call-graph'. from Zhouyi Zhou.
