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.

A synctask is created that would scan the indices from
.shard/.remove_me, to delete the shards associated with the
gfid corresponding to the index bname and the rate of deletion
is controlled by the option features.shard-deletion-rate whose
default value is 100.
The task is launched on two accounts:
1. when shard receives its first-ever lookup on the volume
2. when a rename or unlink deleted an inode

(part 1)
PROBLEM:
Shards are deleted synchronously when a sharded file is unlinked or
when a sharded file participating as the dst in a rename() is going to
be replaced. The problem with this approach is it makes the operation
really slow, sometimes causing the application to time out, especially
with large files.
SOLUTION:
To make this operation atomic, we introduce a ".remove_me" directory.
Now renames and unlinks will simply involve two steps:
1. creating an empty file under .remove_me named after the gfid of the file
participating in unlink/rename
2. carrying out the actual rename/unlink
A synctask is created (more on that in part 2) to scan this directory
after every unlink/rename operation (or upon a volume mount) and clean
up all shards associated with it. All of this happens in the background.
The task takes care to delete the shards associated with the gfid in
.remove_me only if this gfid doesn't exist in backend, ensuring that the
file was successfully renamed/unlinked and its shards can be discarded now
safely.

This patch creates a new way of defining message id's that is easier
and less error prone because it doesn't require so many manual changes
each time a new component is defined or a new message created.
