<title>rpc/transport: Missing a ref on dict while creating transport object</title>

<content type='text'>
while creating rpc_tranpsort object, we store a dictionary without
taking a ref on dict but it does an unref during the cleaning of the
transport object.

So the rpc layer expect the caller to take a ref on the dictionary
before passing dict to rpc layer. This leads to a lot of confusion
across the code base and leads to ref leaks.

Semantically, this is not correct. It is the rpc layer responsibility
to take a ref when storing it, and free during the cleanup.

I'm listing down the total issues or leaks across the code base because
of this confusion. These issues are currently present in the upstream
master.

1) changelog_rpc_client_init

2) quota_enforcer_init

3) rpcsvc_create_listeners : when there are two transport, like tcp,rdma.

4) quotad_aggregator_init

5) glusterd: init

6) nfs3_init_state

7) server: init

8) client:init

This patch does the cleanup according to the semantics.

<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 doesn't make sense to calloc (allocate and clear) memory

It may be optimized by the compiler, or have a microscopic
performance improvement.

In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.

1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.

Only compile-tested!

.. and allocate memory as much as needed.

xlators/nfs/server/src/mount3.c :

Don't blindly allocate PATH_MAX, but strlen() the string and allocate
appropriately.
Also, align error messges.

strncpy may not be very efficient for short strings copied into
a large buffer: If the length of src is less than n,
strncpy() writes additional null bytes to dest to ensure
that a total of n bytes are written.

Instead, use snprintf().
