Prefer timespec_now_realtime() and gf_time() over clock_gettime() and time(), use gf_tvdiff() and gf_tsdiff() where appropriate, drop unused time_elapsed() and leftovers in 'struct posix_private'.

Since this xlator measures time intervals in seconds, timespec_now() may be replaced with simpler gf_time(). Consistently use time_t and uint32_t for timeouts, better error checking in mdc_reconfigure(), adjust comments and messages as well.

mdc_inode_xatt_set() blindly cleared current cache when dict was not NULL, even if there was no xattr requested. This patch fixes this by only calling mdc_inode_xatt_set() when we have explicitly requested something to cache.

This causes mdc_xattr_list_populate() NOT to add "user.swift.metadata" as an xattr in the list of attrs we look at in some paths of the code. This is documented @ https://github.com/gluster/glusterfs/issues/775 Change-Id: Ie3d676c74a2f333beeacc302e253efe9f9942d1a updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com>
Null character string is a valid xattr value in file system. But for
those xattrs processed by md-cache, it does not update its entries if
value is null('\0'). This results in ENODATA when those xattrs are
queried afterwards via getxattr() causing failures in basic operations
like create, copy etc in a specially configured Samba setup for Mac OS
clients.
On the other side snapview-server is internally setting empty string("")
as value for xattrs received as part of listxattr() and are not intended
to be cached. Therefore we try to maintain that behaviour using an
additional dictionary key to prevent updation of entries in getxattr()
and fgetxattr() callbacks in md-cache.

1. For parallel writes from nfs-ganesha, two fops with two generations, but the fops reply maybe returned disordered. 2. The inode md-cache timeout should not increase conf->generation. With this patch, 1, Fop only gets generation from inode md-cache or conf, does not increase it. 2. The generation is increased at upcall invalidate, estal/enoent error invalidate, reply with zeroed out stat from write-behind.

The "struct iatt" in iatt.h is using int64_t types for storing the atime, mtime and ctime. Therefore the struct 'struct md_cache' in md-cache.c should also use this types to avoid an integer overflow. This can happen e.g. if someone uses a very high default-retention-period in the WORM-Xlator.
