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.

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(). Where possible, ensure there's
no truncation of the output.
Also:
- save the result of strlen() and re-use it when possible.
- move from strlen to SLEN (sizeof() ) for const strings.
- switch a strncpy to a memcpy.
Compile-tested only!

Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...
Only compile-tested!

libgfchangelog was encoding path using spec rfc3986, but encoding only
required for SPACE and NEWLINE chars since the NEWLINE char is used as
record separator and SPACE as field separator in the parsed changelogs
output.
Changed the encoding function to encode only SPACE and NEWLINE.

various xlators and other components are invoking system calls
directly instead of using the libglusterfs/syscall.[ch] wrappers.
If not using the system call wrappers there should be a comment
in the source explaining why the wrapper isn't used.

Problem:
Crash observed in gf_changelog_process and
gf_changelog_callback_invoker.
Cause:
Assignments to arguments passed to thread is done
post thread creation. If the thread created gets
scheduled before the assignment and access these
variables, it would crash with segmentation fault.
Solution:
Assignments to arguments are done prior to the thread
creation.

On Linux systems we should use the libuuid from the distribution and not
bundle and statically link the contrib/uuid/ bits.
libglusterfs/src/compat-uuid.h has been introduced and should become an
abstraction layer for different UUID APIs. Non-Linux operating systems
should implement their compatibility layer there.
Once all operating systems have an implementation in compat-uuid.h, we
can remove contrib/uuid/ from the repository completely.

When libgfchangelog is linked with non xlator application,
it should point to 'master' xlator which is initiated separately.
When ever a new thread is created, 'THIS' points to the global
xlator. 'THIS' should point to corresponding xlator even then.
This patch adjusts the pointer accordingly.

Coverity CID 1288822 (#1 of 2)
strncpy executed with a limit equal to the target array
size potentially leaves the target string not null terminated.
In this case the strncpy is not needed due to the snprintf
with the same target buffer which follows immediately.
This patch also removes the now unneeded scratch_dir
argument to gf_changelog_init_history(), which is semantically
correct, since scratch_dir has previously been filled into
jnl->jnl_working_dir by the caller, and this is now used to
fill hist_scratch_dir.

This patch introduces RPC based communication between the changelog
translator and libgfchangelog. It replaces the old pathetic stream
based interaction that existed earlier (due to time constraints :-/).
Changelog, upon initialization starts a RPC server (rpcsvc) allowing
clients to invoke a probe API as a bootup mechanism to request for
event notifications. During probe, clients can choose an event
filter specifying the type(s) of events they are interested in. As
of now there is no way to change the event notification set once
the probe RPC call is made, but that is easier to implement.
The actual event notifications is done on a separate RPC session.
The client (libgfchangelog) itself starts and RPC server which the
changelog translator "connects back" during probe. Notifications
are dispatched by a bunch of threads from the server (translator)
and the client optionally orders them if ordered notifications
are requried. FOPs fill in their respective event details in a
buffer (rot-buffs to be particular) and a bunch of threads
(consumers) swap the buffers out of roatation and dispatch them
via RPC. To avoid writer starvation, then number of dispatcher
threads is one less than the number of buffer list in rot-buffs.x
libgfchangelog becomes purely callback based -- upon event
notification from the server (and re-ordering them if required)
invoke a callback routine specified by consumer(s).
A major part of the patch is also aimed at providing backward
compatibility for geo-replication, which was one of the main
consumer of the stream based API. Also, this patch does not\
"turn on" event notifications for all fops, just a bunch which
is currently in requirement. Another pain point is that the
server does not filter events before dispatching it to the
clients. That load is taken up by the client itself (although
it's done at the library layer rather than making it hard on
the callback implementor). This needs improvement and care
needs to be taken to not load the server up with expensive
filtering mechanisms.
