io-stats: new counters

2010-03-04T10:04:16+00:00

Add new counters and statistics for:

a) total read data - since process start, last interval and per fd
b) total write data - since process start, last interval and per fd
c) counts of read IO block size - since process start, last interval and per fd
d) counts of write IO block size - since process start, last interval and per fd
e) counts of all FOP types passing through it

Usage:

1. For dumping global stats

sh# setfattr -n io-stats-dump /tmp/filename /mnt/gluster

2. For enabling per-fd stats

option dump-fd-stats on

These appear in rarely hit error cases or test/demo code so nothing
serious, in fact.
