logic. Also remove a stray debug check.

Ganesa ULP needs to see a sane progression of attrs in the CREATE
path.
With this change shell actions like
$ echo "hi" > /nfs41/mybucket/mom
work as expected.

Possibly RGW vnodes should cache Unix attrs, it would reduce the
latency of (frequent) getattr calls, and eventually lines up with
more materialized Unix attributes.

Incremental work to support CREATE,OPEN,WRITE*,CLOSE transactions.
Adds a new tuple-based signature for RGWFileHandle::lookup_fh, and
fixes an inconsisten initialization of fhk and fh.fh_hk.

The current API relies on rgw_lookup and rgw_lookup_filehandle to
return file handle instances, and like POSIX, needs to deal in some
way with the NFS/POSIX open-for-create concept.
For now, allow rgw_lookup to return the canonical instance for an
object being created, i.e., if the option RGW_LOOKUP_FLAG_CREATE
is passed. (I added an RGW_OPEN_FLAG_CREATE also, but it doesn't
do anything.)

The fids1, fids2 vectors were confusing, as fids2 mapped the
objects in the union of all buckets.
Now there's a matrix of <bucket,object>, and it's trivial to
scan the objects in any one bucket.

* implement a stat operation over RGWGetObj (returning early)
* use stat to validate rgw_lookup
* use stat to implement rgw_getattr

This a cache-line-friendly set of primitives for
a) shareded, intrusive maps based on boost::intrusive
b) an LRU system based on them
The system uses per-lane (shard) locks. Lane count, front cache
size, and lock type are template params.
Initially, use this in preference to an unshareded map or hashtable,
in new RGW code.

The changes to GET_OBJECT and PUT_OBJECT test options are needed,
since they are (re) writing the same object.
Sadly, READV_AFTER_WRITEV is failing at page offset 7.

The model in the rgw_readv call is the caller owns the struct rgw_uio,
and uses it to pass uio_offset.
The caller returns the rgw_uio filled out, and provides indirectly
rgw_uio->uio_vio (the full private data is at uio->uio_p1 on return,
the caller (p==private) must not touch it. The caller returns
private data in rgw_readv_release() when finished.
Meanwhile rgw_writev is atomic.

Update rgw_write to return bytes written as an OUT argument,
use and verify in PUT test.
A new WRITE_READ_VERIFY test writes 16 checksummed, 64K data pages
to the object when --bulk specified. The returned write value is
checked, but pages not re-read (yet).

Remove duplicated init step. Just reference the global
Ceph context for the library instance(s).
The immediate effect of this is to bring the (correctly initialized)
global context into all call paths, which (e.g.) fixes debug
log prints within subsystems.
