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(). Check for truncated output
where applicable.
Also:
- save the result of strlen() and re-use it when possible.
- move from strlen to SLEN (sizeof() ) for const strings.

As the value read from the file is not checked for the range,
and the same value is directly used to allocate, and read further
values, it can cause major issues.

I suspect we've allocated and then set to '\0' an
additional byte for no reason: gf_asprintf() allocates
enough inc. the terminating null; data->len took that
additional byte into account; memcpy() it back
took care of that terminating null byte as well.
Also, unrelated, implemented str_to_data() via
strn_to_data().

others.
They all take as a parameter the key length, instead of strlen() it.
In most cases, we know the key length, we just never bothered to save and pass it along.
(We most likely sprintf'ed it earlier and the return value could have been used).
A more interesting addition is dict_set_nstrn() [horrible name. Ideas are welcome].
It accepts both the string length and the key length and avoids strlen() both.
Some of it can be calculated on compile-time, btw.
For example:
dict_set_str (dict, "key", "all");
Should become:
dict_set_nstrn (dict, "key", sizeof ("key"), "all", sizeof ("all"));

strncpy may not be very efficient for sort 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, do a quick calc to see how much we really need and use
snprintf() to copy as much.
Also, move from CALLOC to MALLOC, as we are writing to this newly
allocated memory right away and add terminating null.
Lastly, removed some dead code. I did the same optimization as above
to it, only to find out no one is using it.

modifications
PROBLEM:
Stats of dentries that are readdirp'd ahead can become stale due to
fops like writes, truncate etc that modify the file pointed by
dentries. When a readdir is finally wound at offset corresponding to
these entries, the iatts that are returned to the application come
from readdir-ahead's cache, which are stale by now. This problem gets
further aggravated when caching translators/modules cache and continue
to serve this stale information.
FIX:
* Store the iatt in context of the inode pointed by dentry.
* Whenever the inode pointed by dentry undergoes modification, in cbk
of modification fop, update the iatt stored in inode-ctx to reflect
the modification.
* When serving a readdirp response from application, update iatts of
dentries with the iatts stored in the context of inodes pointed by
these dentries.
* Some fops don't have valid iatts in their responses. For eg., write
response whose data is still cached in write-behind will have zeroed
out stat. In this case keep only ia_type and ia_gfid and reset rest
of the iatt members to zero.
- fuse-bridge in this case just sends "entry" information back to
kernel and attr is not sent.
- gfapi sets entry->inode to NULL and zeroes out the entire stat
* There is one tiny race between the entry creation and a readdirp on
its parent dir, which could cause the inode-ctx setting and inode
ctx reading to happen on two different inode objects. To prevent
this, when entry->inode doesn't eqaul to linked_inode,
- fuse-bridge is made to send only "entry" information without
attributes
- gfapi sets entry->inode to NULL and zeroes out the entire stat.

gf_mkostemp is borrowed from GLibC a long time back,
we now have mkostemp or mkstemp alternatives with all
distributions and versions that we care for.
As a result removing this from the contrib directory
and modifying the one instance that is still using the
same.
This is part of code cleanup as we cleaned up coverity
SECUR_TEMP errors.

Update to latest xxHash, which is supposed to faster with small keys.
Specifically, updated to 3064d42e7d74b0921bdd1818395d9cb37bb8976a,
which is a bit higher than 0.6.5.
Compiled hopefully with namespace (XXH_NAMESPACE=GF_),
which allows to use XXH() funcs with no fear they'll 'leak'
from our library.
Only compile tested!
xxhsum is modified to display messages which was conflicting
with regression tests (TAP harness). So modified the
gfid2path_fuse.t and gfid2path_nfs.t to adhere to that.

There's a good chance the compiler is smart enough to remove it
anyway, but it can't hurt - I hope.

Problem: Sometimes client connection is failed after throwing
error "cleanup flag is set for xlator Try again later".
The situation comes only after get a detach request but
the brick stack is not completely detached and at the same time
the client initiates a connection with brick
Solution: To resolve the same check cleanup_starting flag in get
xlator_by_name_or_type, this function call by server_setvolume
to attach a client with brick.

Current invalidation of stats in wb_readdirp_cbk is prone to races. As
the deleted comment explains,
<snip>
We cannot guarantee integrity of entry->d_stat as there are cached
writes. The stat is most likely stale as it doesn't account the cached
writes. However, checking for non-empty liability list here is not a
fool-proof solution as there can be races like,
1. readdirp is successful on posix
2. sync of cached write is successful on posix
3. write-behind received sync response and removed the request from
liability queue
4. readdirp response is processed at write-behind.
In the above scenario, stat for the file is sent back in readdirp
response but it is stale.

while in cache
PROBLEM:
Entries that are readdirp'd ahead can undergo modification in terms
of writes, truncates which could modify their iatts. When a readdir
is finally wound at offset corresponding to these entries, the iatts
that are returned to the application come from readdir-ahead's cache,
which are stale by now. This problem gets further aggravated when caching
translators/modules cache and continue to serve this stale information.
FIX:
Whenever a dentry undergoes modification, in the cbk of the modification fop,
a "dirty" flag (default 0) is set in its inode ctx. When it's time for
readdir-ahead to serve these entries, it will read the inode ctx and check
if the entry is "dirty", and if it is, set the entry's attrs to all zeroes,
as an indicator to fuse, md-cache etc not to cache these attributes.
Also there is one tiny race between the entry creation and a readdirp on its
parent dir, which could cause the inode-ctx setting and inode ctx reading to
happen on two different inode objects. To prevent this, fuse-bridge is made to
drop entries for which dentry->inode is not the same as linked inode,
in readdirp cbk.

Bundling libuuid is not needed anymore, all current distributions
provide it now.
Some OS's provide their own uuid_*() functions in libc. These may not be
fully compatible with libuuid.so found on Linux systems. In that case,
either e2fsprogs-libuuid can be installed, or support for the native
uuid_*() functions can be added to libglusterfs/src/compat-uuid.h.

Newer FreeBSD versions (noticed with 10.3-RELEASE) provide a event.h
file that on occasion gets included instead of the libglusterfs file.
When this happens, 'struct event_pool' will not be defined and building
will fail with errors like:
autoscale-threads.c:18:55: error: incomplete definition of type 'struct event_pool'
int thread_count = pool->eventthreadcount;
~~~~^
autoscale-threads.c:17:16: note: forward declaration of 'struct event_pool'
struct event_pool *pool = ctx->event_pool;
^
This problem is caused by 'pkg-config --cflags uuid' that adds
/usr/local/include to the GF_CPPFLAGS. The use of libuuid is preferred
so that the contrib/uuid/ directory can be removed.
By renaming event.h to gf-event.h there is no conflict between the
different event.h files anymore and compiling on FreeBSD works without
issues.

mkstemp as per the Linux man page, uses 0600 as the permission
bits when creating the file. This is hence safe and a Coverity
warning that should be ignored.
Further, we are mostly a multi-threaded program in all our daemons
and cannot set and unset umask at will in a multi-threaded
program, to address the coverity issue.
This change attempts to nudge coverity to ignore this warning,
using the pattern,
/* coverity[EVENT_TAG_NAME] ... */
<line of code that has the issue>
This commit is an experiment, if post merge the next coverity
report ignores these errors, the above pattern (as found using
an internet search) works and can be applied to certain other
warnings as well.

Starting in Fedora 26 which has gcc-7.1.x, -Wformat-trunction is enabled
with -Wformat, resulting in a flood of new warnings. This many warnings
is a concern because it makes it hard(er) to see other warnings that
should be addressed.
An example is at
https://kojipkgs.fedoraproject.org//packages/glusterfs/3.12.0/1.fc28/data/logs/x86_64/build.log
For more info see https://review.gluster.org/#/c/18267/
I can't find much (or good) documentation on the heuristics the
compiler uses for this warning. In the case of printing integer types
it appears it looks at the available space in the destination and the
range of values for the variable and/or its type.
To address the specific question about why 0x3ff versus 0xfff to mask
the value, either would suffice to hint to the compiler that the
printed value will fit in three characters. But the loop is from
0...1023 (or 0...0x3ff if you prefer) so I chose that as a more
"accurate" mask to use as it exactly matches the range of values of
the loop.

Since setxattr and removexattr fops cbk do not carry poststat,
the stat cache was being invalidated in setxatr/remoxattr cbk.
Hence the further lookup wouldn't be served from cache.
To prevent this invalidation, md-cache is modified to get
the poststat in set/removexattr_cbk in dict.
