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.

The bitrot scrubber takes 'hourly/daily/biweekly/monthly'
as the values for 'scrub-frequency'. There is no way
to schedule the scrubbing when the admin wants it.
Ondemand scrubbing brings in the new option 'ondemand'
with which the admin can start scrubbing ondemand.
It starts the scrubbing immediately.
Ondemand scrubbing is successful only if the scrubber
is in 'Active (Idle)' (waiting for it's next frequency
cycle to start scrubbing). It is not entertained when
the scrubber is in 'Paused' or already running.
Here is the command line syntax.
gluster volume bitrot <vol name> scrub ondemand

The patch does following changes.
1. Introduce scrubber monitor thread.
2. Move scrub status related APIs to separate file
and make part of libbitrot library.
Problem:
Earlier, each child of the scrubber was maintaining
the state machine and hence there was no way to track
the start and end time of scrubbing as each brick has
it's own start and end time. Also each brick was maintaining
it's own timer wheel instance. It was also not possible
to get scrubbed files count per session as we could not
get last child which finishes scrubbing to reset it to
zero.
Solution:
Introduce scrubber monitor thread. It does following.
1. Maintains the scrubber state machine. Earlier each
child had it's own state machine. Now, only monitor
maintains on behalf of all it's children.
2. Maintains the timer wheel instance. Earlier each
child had it's own timer wheel instance. Now, only
monitor maintains on behalf of all it's children.
As a result, we can track the scrub statistics easily
and correctly.

A bunch of command line options for scrubber tempted the use of
state machine to track current state of scrubber under various
circumstances where the options could be in effect.
