* libglusterfs changes to add new fop
* Fuse changes:
- Changes in fuse bridge xlator to receive and send responses
* posix changes to perform the op on the backend filesystem
* protocol and rpc changes for sending and receiving the fop
* gfapi changes for performing the fop
* tools: glfs-copy-file-range tool for testing copy_file_range fop
- Although, copy_file_range support has been added to the upstream
fuse kernel module, no release has been made yet of a kernel
which contains the support. It is expected to come in the
upcoming release of linux-4.20
So, as of now, executing copy_file_range fop on a fused based
filesystem results in fuse kernel module sending read on the
source fd and write on the destination fd.
Therefore a small gfapi based tool has been written to be able
test the copy_file_range fop. This tool is similar (in functionality)
to the example program given in copy_file_range man page.
So, running regular copy_file_range on a fuse mount point and
running gfapi based glfs-copy-file-range tool gives some idea about
how fast, the copy_file_range (or reflink) can be.
On the local machine this was the result obtained.
mount -t glusterfs workstation:new /mnt/glusterfs
[root@workstation ~]# cd /mnt/glusterfs/
[root@workstation glusterfs]# ls
file
[root@workstation glusterfs]# cd
[root@workstation ~]# time /tmp/a.out /mnt/glusterfs/file /mnt/glusterfs/new

[root@workstation ~]# time glfs-copy-file-range $(hostname) new /tmp/glfs.log /file /rrr
OPEN_SRC: opening /file is success

FSTAT_SRC: fstat on /rrr is success
copy_file_range successful
real 0m0.309s
user 0m0.039s

This tool needs following arguments
1) hostname
2) volume name
3) log file path
4) source file path (relative to the gluster volume root)
5) destination file path (relative to the gluster volume root)
"glfs-copy-file-range <hostname> <volume> <log file path> <source> <destination>"
- Added a testcase as well to run glfs-copy-file-range tool
* io-stats changes to capture the fop for profiling
* NOTE:
- Added conditional check to see whether the copy_file_range syscall
is available or not. If not, then return ENOSYS.
- Added conditional check for kernel minor version in fuse_kernel.h
and fuse-bridge while referring to copy_file_range. And the kernel
minor version is kept as it is. i.e. 24. Increment it in future
when there is a kernel release which contains the support for
copy_file_range fop in fuse kernel module.

The include path in glusterfs-api.pc looks like
-I${includedir}/glusterfs
However, client code will include the glusterfs headers using
#include <glusterfs/api/glfs.h>
rather than
#include <api/glfs.h>
which makes the "/glusterfs" part entirely unnecessary.
More importantly, on some platforms such as FreeBSD, the header files
for glusterfs will be installed in /usr/local/include, which is *not*
part of the compiler's default include path, so compilation will fail
with something like
fatal error: 'glusterfs/api/glfs.h' file not found
#include <glusterfs/api/glfs.h>
^~~~~~~~~~~~~~~~~~~~~~
The fix is to simply drop the extra "/glusterfs". The same change
is applied to other *.pc files as well, althought I haven't actually
tested those.
A test program (gfapi-load-volfile) and the glfsxmp example
application were using the wrong include paths, so they had to be
fixed as well.

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.

These two functions add support for POSIX ACLs through the GFAPI-handle
interface.
The initial infrastructure for POSIX ACLs based on libacl has been added
with the required changes to the POSIX xlator:

NetBSD does not support POSIX ACLs, so using any of the functions should
return ENOTSUP.

According to libtool three individual numbers stand for
CURRENT:REVISION:AGE, or C:R:A for short. The libtool
script typically tacks these three numbers onto the end
of the name of the .so file it creates. The formula for
calculating the file numbers on Linux and Solaris is
/path/to/library/<library_name>.(C - A).(A).(R)
As you release new versions of your library, you will
update the library's C:R:A. Although the rules for changing
these version numbers can quickly become confusing, a few
simple tips should help keep you on track. The libtool
documentation goes into greater depth.
In essence, every time you make a change to the library and
release it, the C:R:A should change. A new library should start
with 0:0:0. Each time you change the public interface
(i.e., your installed header files), you should increment the
CURRENT number. This is called your interface number. The main
use of this interface number is to tag successive revisions
of your API.
The AGE number is how many consecutive versions of the API the
current implementation supports. Thus if the CURRENT library
API is the sixth published version of the interface and it is
also binary compatible with the fourth and fifth versions
(i.e., the last two), the C:R:A might be 6:0:2. When you break
binary compatibility, you need to set AGE to 0 and of course
increment CURRENT.
The REVISION marks a change in the source code of the library
that doesn't affect the interface-for example, a minor bug fix.
Anytime you increment CURRENT, you should set REVISION back to 0.

This way PKG_MODULE() autoconf test checks for required API
rather than release version (e.g required API could be in all
all of 3.4.5, 3.5.1, 3.6.4 etc.)
With the first "release" of gfapi, the current version (4) will
be frozen.
Version 3 is sufficient for QEMU's requirement. Version 4 is
necessary for Samba VFS
