- Add O_TRUNC support for nfs_create
- Handle OOM during create
- Return more stats fields as part of readdir since we get these for "free"
when we use READDIRPLUS
- Follow symlinks during path resolution
- Add lchown, lstat and lutimes
- Replace all [u_]quad types with [u]int types in our RPC layer
- Solaris build fixes

The NFS spec states:
"The ratio of the directory entry size to the size of the attributes plus the
size of the file handle is usually at least 8 to 1."
Though implementation dependent the spec implies that the previous 1 to 1 ratio
could have a detrimental impact on the performance of the server due to most of
the data per VOP_READDIR call being wasted.
The Linux kernel uses the 8 to 1 ratio.

Add nfs_access2(), like nfs_access() but it returns the individual
statuses of R_OK, W_OK and X_OK rather than a single success or failure
status. This saves the latency and overhead of multiple lookups if an
application tries to determine the status of each of R_OK, W_OK and
X_OK.

Map ACCESS3_{MODIFY,EXTEND,DELETE} to W_OK and ACCESS3_{LOOKUP,EXECUTE}
to X_OK so that nfs_access() gives sensible results for directories.

This file has been obsolete for a long time. At least since libfs got
its own internal marshalling support: ZDR.

All current platforms have a quad type that maps to a 64bit scalar.
But there are platforms where quad maps to a 64bit non-scalar.
Replace quad with int64 in the protocol definitions and the ZDR layer
so that these fields will map to a 64 bit scalar also on those platforms
where quad can not be used.

Since the user callback may perform operations on the nfsfh (e.g. it
might close it), all updates should be done before the user callback is
called.

Map NFS3ERR_NOTEMPTY to ENOTEMPTY rather than EEXIST. POSIX allows
either EEXIST or ENOTEMPTY for rmdir on a non-empty directory but
ENOTEMPTY is more explicit and in line with Linux, OS X, FreeBSD and
OpenBSD's behavior.

Follow symlinks during path resolution. If the symlink points outside
the mount, -ENOENT is returned. This is slightly different behavior
from the in-kernel NFS client where symlinks pointing outside the mount
get resolved to local paths.
The algorithm for symlink resolution is simple and stupid. If a symlink
is encountered, the path is rewritten and path resolution begins again
from the root filehandle. A count is kept to prevent loops. This is
not particularly efficient but it is good enough for now.

Set as much stat information as possible for stat, stat64, fstat and
readdir.
Fill in dev to the given fsid.
Fill in rdev to the given major and minor numbers.
Set the file type bits in the mode from the type returned by the server.
Set the number of blocks used based on the number of bytes used in
blocks of size 512 (which is what stat(2) uses), rounded up.
Fill in the nanosecond timestamps.

Since rpc_connect_async sets autoreconnect to 0, turn autoreconnect on

Add a new family of functions, nfs_create, like nfs_creat but takes an
additional flags argument which allows extra flags like O_SYNC, O_EXCL
and O_APPEND to be specified.
Include the zdr header from all raw lowlevel headers so that we don't have to
include it manually from apps.
