libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.
Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs
This change although big, is just moving around the headers and
making it correct when including these headers from other sources.
This helps us correctly include libglusterfs includes without
namespace conflicts.

Summary:
- Using sampling feature you can record details about every Nth FOP.
The fields in each sample are: FOP type, hostname, uid, gid, FOP priority,
port and time taken (latency) to fufill the request.
- Implemented using a ring buffer which is not (m/c) allocated in the IO path,
this should make the sampling process pretty cheap.
- DNS resolution done @ dump time not @ sample time for performance w/
cache
- Metrics can be used for both diagnostics, traffic/IO profiling as well
as P95/P99 calculations
- To control this feature there are two new volume options:
diagnostics.fop-sample-interval - The sampling interval, e.g. 1 means
sample every FOP, 100 means sample every 100th FOP
diagnostics.fop-sample-buf-size - The size (in bytes) of the ring
buffer used to store the samples. In the even more samples
are collected in the stats dump interval than can be held in this buffer,
the oldest samples shall be discarded. Samples are stored in the log
directory under /var/log/glusterfs/samples.
- Uses DNS cache written by sshreyas@fb.com (Thank-you!), the DNS cache
TTL is controlled by the diagnostics.stats-dnscache-ttl-sec option
and defaults to 24hrs.
Test Plan:
- Valgrind'd to ensure it's leak free
- Run prove test(s)
- Shadow testing on 100+ brick cluster

Summary:
- Adds a thread to the io-stats translator which dumps out statistics
every N seconds where N is configurable by an option called
"diagnostics.stats-dump-interval"
- Thread cleanly starts/stops when translator is unloaded
- Updates macros to use "Atomic Builtins" (e.g. intel CPU extentions) to
use memory barries to update counters vs using locks. This should
reduce overhead and prevent any deadlock bugs due to lock contention.
Test Plan:
- Test on development machine
- Run prove -v tests/basic/stats-dump.t
