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.

This patch fixes compile warnings that appear with newer compilers. The solution applied is only to remove the warnings, but it doesn't always solve the problem in the best way. It assumes that the problem will never happen, as the previous code assumed.

The command basically allows replace brick with src and
dst bricks as same.
Usage:
gluster v reset-brick <volname> <hostname:brick-path> start
This command kills the brick to be reset. Once this command is run,
admin can do other manual operations that they need to do,
like configuring some options for the brick. Once this is done,
resetting the brick can be continued with the following options.
gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force}
Does the job of resetting the brick. 'force' option should be used
when the brick already contains volinfo id.
Problem: On doing a disk-replacement of a brick in a replicate volume
the following 2 scenarios may occur :
a) there is a chance that reads are served from this replaced-disk brick,
which leads to empty reads. b) potential data loss if next writes succeed
only on replaced brick, and heal is done to other bricks from this one.
Solution: After disk-replacement, make sure that reset-brick command is
run for that brick so that pending markers are set for the brick and it
is not chosen as source for reads and heal. But, as of now replace-brick
for the same brick-path is not allowed. In order to fix the above
mentioned problem, same brick-path replace-brick is needed.
With this patch reset-brick commit {force} will be allowed even when
source and destination <hostname:brickpath> are identical as long as
1) destination brick is not alive
2) source and destination brick have the same brick uuid and path.
Also, the destination brick after replace-brick will use the same port
as the source brick.

Starting with glibc-2.23 (i.e. what's in Fedora 25), readdir_r(3) is marked as deprecated. Specifically the function decl in <dirent.h> has the deprecated attribute, and now warnings are thrown during the compile on Fedora 25 builds. The readdir(_r)(3) man page (on Fedora 25 at least) and World+Dog say that glibc's readdir(3) is, and always has been, MT-SAFE as long as only one thread is accessing the directory object returned by opendir(). World+Dog also says there is a potential buffer overflow in readdir_r(). World+Dog suggests that it is preferable to simply use readdir(). There's an implication that eventually readdir_r(3) will be removed from glibc. POSIX has, apparently deprecated it in the standard, or even removed it entirely. Over and above that, our source near the various uses of readdir(_r)(3) has a few unsafe uses of strcpy()+strcat(). (AFAIK nobody has looked at the readdir(3) implemenation in *BSD to see if the same is true on those platforms, and we can't be sure of MacOS even though we know it's based on *BSD.)
