Update the configure to add some sanity -W arguments.
A good start is probably :
-Wall -Werror -Wshadow -Wno-write-strings -Wstrict-prototypes
-Wpointer-arith -Wcast-align -Wno-strict-aliasing
Fixup the paces in the code that triggers.
(one of which is readahead code which is perhaps broken?)

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.

Include the proper headers to fix warnings like:
libnfs-sync.c:1529:3: warning: implicit declaration of function 'gettimeofday' [-Wimplicit-function-declaration]
libnfs-zdr.c:506:2: warning: implicit declaration of function 'getuid' [-Wimplicit-function-declaration]

Add lchmod which is like chmod but operates on the symbolic link itself
if the destination is a symbolic link.

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.
Previously nfs_read and nfs_write used to use nfs_pread and nfs_pwrite respectively.
In preparation of getting the file position handling right this has to be detangled.

Add chdir and getcwd and store cwd in the nfs_context.
Add functions to process the paths specified and normalize them
by performing the transforms :
// -> /
/./ -> /
^/../ -> error
^[^/] -> error
/string/../ -> /
/$ -> \0
/.$ -> \0
^/..$ -> error
/string/..$ -> /
Update the path lookup function to allow specifying relative paths based on
cwd for all functions.

If status is non-zero in the mount callback, then the datapointer might be NULL
so we should not dereference it into an exports pointer before we have checked the status.
This would otherwise cause crashes.
This patch switches libnfs over to use precompiled rpcgen files
and using ZDR. ZDR is a trivial reimplementation of XDR that is built in
into libnfs.
This removes the dependencies of rpc/xdr completely and allow us to build on any
system, even systems where rpcgen and librpc/libxdr are not generally available.
Once a NFS TCP connection has been idle for a very long time, say
10-15 minutes, it is common that NFS servers will tear down the TCP connection.
So add code to re-connect to the NFS server and re-issue any i/o that might have been in flight (unlikely unless the server has hung)
While it is sufficient to just reconnect to tcp port 2049, it was much simplet to just utilize the nfs_mount() function.
This means that instead of just reconnecting TCP port 2049, we do a full blown
nfs mount via portmapper and mountd protocols.
