Unlink of a sharded file with holes was leading to EINVAL errors
because it was being wound on non-existent shards (those blocks that
fall in the hole region). loc->inode was NULL in these cases and
dht_unlink used to fail the FOP with EINVAL for failure to fetch
cached subvol for the inode.
The fix involves winding unlink on only those shards whose corresponding
inodes exist in memory.

This patch does the following:
* reverts commit b467af0e99b39ef708420d3f7f6696b0ca618512
* changes ownership on shards under /.shard to be root:root
* makes readv, writev, [f]truncate, rename, and unlink fops
to perform operations on files under /.shard with
frame->root->{uid,gid} as 0.
This would ensure that a [f]setattr on a sharded file
does not need to be called on all the shards associated with it.

The only place where shard translator was initialising inode ctx
was lookup callback. But if the inodes are created and linked through
readdirp, shard_lookup() path _may_ not be exercised before FUSE
winds other fops on them. Since shard translator does an
inode_ctx_get() first thing in most fops, an uninitialised ctx could
cause it to fail the operation with ENOMEM.
The solution would be to also initialise inode ctx if it has not been
done already in readdir(p) callback.

On enabling features.shard on a volume which already has few files,
performing operations on the mount was causing excessive logging of
messages of the following kind:
[2015-08-05 10:57:48.743352] E [shard.c:232:shard_modify_size_and_block_count]
2-dis-shard: Failed to get trusted.glusterfs.shard.file-size for
0b2bd401-c438-4d57-8ae5-8d26105d3396
Turns out this is coming from shard_readdir_cbk() where the shard
translator unconditionally looks for the xattr
'trusted.glusterfs.shard.file-size' in every entry's rsp dict and
logs this error on not finding it. But files that are not sharded
(i.e., the ones that were created before sharding was enabled on the volume)
will not (and should not) have this xattr associated with them.
So these logs are misleading and must be suppressed in readdir(p).

Instead of using dict_get_ptr, dict_get_uint64 was used. If the first byte of
the value is '\0' then size is returned as 0 because strtoull is used in
data_to_uint64. This will make it seem like the file is not sharded at all.

This change is done in [f]truncate, rename, unlink and readv.
Also, this patch also makes lookup in shard delete GF_CONTENT_KEY
as a workaround for the problems with read caching of sparse files
by quick-read. A proper solution would involve shard_lookup_cbk()
performing a readv, aggregating and ordering the responses and setting
it in the xdata before unwinding the response to upper translators, which
will be done in a separate patch.

Due to get_lowest_block() being a macro, what needs to be passed
to it is the evaluation of the expression (local->offset - 1), without
which its substitution can cause junk values to be assigned to
local->first_block.
This patch also fixes calls to get_highest_block() where if offset and
size are both equal to zero, it could return negative values.

Problem:
When readdir(p) is performed on '/' and ".shard" happens to be
the last of the entries read in a given iteration of dht_readdir(p)
(in other words the entry with the highest offset in the dirent list
sorted in ascending order of d_offs), shard xlator would delete this
entry as part of handling the call so as to avoid exposing its presence
to the application. This would cause xlators above (like fuse,
readdir-ahead etc) to wind the next readdirp as part of the same req
at an offset which is (now) the highest d_off (post deletion of .shard)
from the previously unwound list of entries. This offset would be less
than that of ".shard" and therefore cause /.shard to be read once again.
If by any chance this happens to be the only entry until end-of-directory,
shard xlator would delete this entry and unwind with 0 entries, causing the
xlator(s) above to think there is nothing more to readdir and the fop is
complete. This would prevent DHT from gathering entries from the rest of
its subvolumes, causing some entries to disappear.
Fix:
At the level of shard xlator, if ".shard" happens to be the last entry,
make shard xlator wind another readdirp at offset equal to d_off of
".shard". That way, if ".shard" happens to be the only other entry under '/'
until end-of-directory, DHT would receive an op_ret=0. This would enable it
to wind readdir(p) on the rest of its subvols and gather the complete picture.
Also, fixed a bug in shard_lookup_cbk() wherein file_size should be fetched
unconditionally in cbk since it is set unconditionally in the wind path, failing
which, lookup would be unwound with ia_size and ia_blocks only equal to that of
the base file.

When a .c file tests for a certain #define, and config.h was not

glusterfs relies on Linux uuid implementation, which
API is incompatible with most other systems's uuid. As
a result, libglusterfs has to embed contrib/uuid,
which is the Linux implementation, on non Linux systems.
This implementation is incompatible with systtem's
built in, but the symbols have the same names.
Usually this is not a problem because when we link
with -lglusterfs, libc's symbols are trumped. However
there is a problem when a program not linked with
-lglusterfs will dlopen() glusterfs component. In
such a case, libc's uuid implementation is already
loaded in the calling program, and it will be used
instead of libglusterfs's implementation, causing
crashes.
A possible workaround is to use pre-load libglusterfs
in the calling program (using LD_PRELOAD on NetBSD for
instance), but such a mechanism is not portable, nor
is it flexible. A much better approach is to rename
libglusterfs's uuid_* functions to gf_uuid_* to avoid
any possible conflict. This is what this change attempts.

Reusing local->xattr_req for the several calls and callbacks per xlator fop
would cause keys set from previous call/cbk (sometimes even by the xlators
below) to remain which in some cases can lead to errors. For instance, the
presence of "trusted.glusterfs.dht.*" keys (which are remnants of the previous
call/cbk), can cause the GF_IF_INTERNAL_XATTR_GOTO() check in DHT to fail when
the same dict is used to wind [f]setxattr.

* Return number of bytes written in writev cbk on success
* Eliminate separate inode table for sharding xlator.
* Fix appearance of "shard" as an option within the
volfile for subvolume of type features/shard.
* Fix values of min and max allowed shard block size
* Return @new as opposed to NULL in shard_create_gfid_dict() on success

Based on the high-level design by Anand V. Avati which can be found @
https://gist.github.com/avati/af04f1030dcf52e16535#sharding-xlator-stripe-20
Still to-do:
* complete implementation of inode write fops - [f]truncate,
zerofill, fallocate, discard
* introduce transaction mechanism in inode write fops
* complete readv
* Handle open with O_TRUNC
* Handle unlinking of all shards during unlink/rename
* Compute total ia_size and ia_blocks in lookup, readdirp, etc
* wind fsync/flush on all shards
Note: Most of the items above are related. Once we come up
with a clean way to determine the last shard/shard count for
a file/file size and the mgmt of sparse regions of the file,
implementing them becomes trivial.
