Restore missing bit for GROUP in FSALattr

Fattr4_To_FSAL_attr forgot to set GROUP bit in the attribute
mask - that tripped NFSv3 which was complaining about 'missing'
attributes.

Also make the message in nfs3_FSALattr_To_Fattr slightly more
useful by including the bits which were missing.

Push caller credentials into FSAL methods

Proxy FSAL needs caller credentials to send over to the
backend server. Unfortunately this requires modification
of FSAL API to push req_op_context from the protocol handlers
via inode cache and into FSAL.

Properly process attributes for special files

When calling functions which create files/directories/links etc
make sure the attributes include correct bits in the mask - caller
does not know which fields are valid without the mask.

And when processing replies use correct sizes for rawdev attributes:
specdata1 and specdata2 are 32 bit integers on NFSv4.

PROXY FSAL - add support for special files

Implement mknode properly - this is very similar to mkdir,
just need to use right object type and make sure device major/minor
is specified.

When creating FIFOs and SOCKs specdata is set in the arguments but
is not used in encoding.

Rework nfs4 attribute to fsal attribute processing

Remove huge switch statement and by-hand xdr encode/decode.  This is
now table driven off of fattr4tab entries and their companion encode/decode
functions.  These functions directly use the XDR translation library.

* Server time for timeset now uses system nanosec resolution

* much tighter error checking

Add loading of librt for Linux builds

The clock_gettime() library call used by the decode_time XDR helper
needs this GLIBC call.  Add librt (where it lives)

Rework callers of nfs4_FSALattr_To_Fattr to drop pexport arg

This arg is already in data.  Drop it as redundant.

Rework PROXY fsal calls to nfs4_FSALattr_To_Fattr

Change args to drop the redundant pexport.

File handle arg used to point directly into the xdr stream (no copy).
This is not safe because it needs to be aligned and xdr doesn't provide
a semantic for zero copy (yet).  So play it safe

Rework pseudo handle and extended attributes attr processing

Now that the big switch is gone in nfs_proto_tools.c, use its
call here and eliminate their big switch statements.
