<title>libglusterfs: Move devel headers under glusterfs directory</title>

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 &lt;&gt; 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.

It's not needed.
There's a good chance the compiler is smart enough to remove it
anyway, but it can't hurt - I hope.

Compile-tested only!

<title>posix: Introduce flags for validity of iatt members</title>

<id>9fd17c1c3c44944ea280c4c15bad0d49b298b8a9</id>
<content type='text'>
v1 of the patch started off as adding new fields to iatt that can be
filled up using statx but the discussions were more around introducing
masks to check the validity of different fields from a RIO perspective.
To that extent, I have dropped the statx call in this version and
introduced a 64 bit mask for existing fields. The masks I have defined
are similar with the statx() flags' masks.

I have *not* changed iatt_to_stat() to use the macros IATT_TYPE_VALID,
IATT_GFID_VALID etc before blindly copying from struct iatt to struct.

Also fixed warnings in xlators because of atime/mtime/ctime seconds
field change from uint32_t to int64_t.

Problem: In glusterfs code base we call mutex_lock/unlock to take
         reference/dereference for a object.Sometime it could be
         reason for lock contention also.

Solution: There is no need to use mutex to increase/decrease ref
          counter, instead of using mutex use gcc builtin ATOMIC
          operation.

Test:   I have not observed yet how much performance gain after apply
        this patch specific to glusterfs but i have tested same
        with below small program(mutex and atomic both) and
        get good difference.

<title>mem-pool: track glusterfs_ctx_t in struct mem_pool</title>

In order to generate statedumps per glusterfs_ctx_t, it is needed to
place all the memory pools in a structure that the context can reach.
The 'struct mem_pool' has been extended with a 'list_head owner' that is
linked with the glusterfs_ctx_t-&gt;mempool_list.

All callers of mem_pool_new() have been updated to pass the current
glusterfs_ctx_t along. This context is needed to add the new memory pool
to the list and for grabbing the ctx-&gt;lock while updating the
glusterfs_ctx_t-&gt;mempool_list.

Updates: #307
