In lookup, if the file has been marked as bad, then bit-rot-stub
was sending the version and signature xattr values as well in the
response dictinary. This is not needed. Only bad file marker has
to be sent.

<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.

When compiling in other architectures there appear many warnings. Some

those architectures.

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(). Ensure sprintf() results do not
truncate.

Also:
- save the result of strlen() and re-use it when possible.
- move from strlen to SLEN or sizeof() for const strings.
- move ret from int32 to int.

Compile-tested only!

<title>features/bitrot: print the path of the corrupted objects</title>

Currently "gluster volume bitrot &lt;volume name&gt; scrub status"
gives the list of the corrupted objects (files as of now).
But only the gfids of those corrupted objects are seen and
one has to do getfattr, find etc operations to get the actual
path of those objects for removal etc.

This change makes an attempt to print the path of those files
as much as possible.

* Try to get the path using the on disk gfid2path xattr.

* If the above operation fails, then go for in memory path
(provided that the object has its dentry
properly created and linked in the inode table of the brick where
the corrupted object is present) So the gfid to path resolution is
a soft resolution, i.e. based on the inode and dentry cache in the
brick's memory. If the path cannot be obtained via inode table also,
then only gfid is printed.

<title>feature/bitrot: remove internal xattrs from lookup cbk</title>

<id>d341f20230b9921391aff22337eaf9be82f44d88</id>
<content type='text'>
Problem:
afr requests all xattrs in lookup via the list-xattr key. If bitrot is
enabled and later disabled, or if the bitrot xattrs were present due to
an older version of bitrot which used to create the xattrs without
enabling the feature, the xattrs (trusted.bit-rot.version in particular)
was not getting filtered and ended up reaching the client stack. AFR, on
noticing different values of the xattr across bricks of the replica,
started triggering spurious metadata heals.

Fix:
Filter all internal xattrs in bitrot xlator before unwinding lookup,
(f)getxattr.

Thanks to Kotresh for the help in RCA'ing.
