There is no need to allocate and deallocate this structue every time
we update the udp destinateion.
For the client side, where we set the destination just once per lifetime
of the context it might not matter too much but once we add udp server support
we will need to update the sockaddr for every rpc we receive.

Add a flags field to rpc_pdu and add a flag that indicates that the PDU
should be discarded as soon as it has been written to the socket.
We do not put it on the waitpdu queue nor do we wait for a reply.
This will later be used for when we are sending replies back to a client
when operating in a server context.

This allows us to use the NULL function for any arbitrary
program/version from rpc_connect_program() instead of the hardcoded support
for mount v3 and nfs v3

In zdr_array we can not use the check that num_elements * element_size
will fit inside the remaining bytes in the ZDR buffer.
The reason for this is that IF it is an array of unions, then
element-size will have the size of the largest arm in that union.
If the array consists of union items that are smaller than the largest arm,
then it becomes likely that this will pack in less than num_elements *
element_size and this it is possible that the array WILL fir in the remaining
bytes.

- Reduce the number of memory allocations in the ZDR layer.
- Check both seconds and nanoseconds field when validating dir cache.
- Invalidate the dir cache immediately if we do something that would cause
it to become stale, such as adding/removing objects from the cache.
- Add options to enable/disable dir caching.
- Discard readahead cache on [p]write and truncate.
- Android fixes
- Windows fixes
- Support timeouts for sync functions
- Add an internal pagecache
- Add nfs_rewinddir(), nfs_seekdir() and nfs_telldir()
- Fix crash in nfs_truncate()
- Fix segfault that can trigger if we rpc_disconnect() during the mount.
- Add support to bind to a specific interface (linux only)

We have not needed an external onc-rpc library for libnfs in a long
long time since the re-write to use a builtin XDR replacement (ZDR).
Remove all references from the project files to my old port of a onc-rpc
library to win32.

`nfs_set_interface` and `rpc_set_interface` APIs, or via the
NFS URL `if=<interface>` parameter. This feature requires
`root` permissions.
NOTE: This has only been compiled and tested on Ubuntu 14.04. It's
unlikely that it'll work on other platforms without modification,
particularly around the inclusion of <net/if.h> and IFNAMSIZ define
in `libnfs-private.h`.
This addresses a bug causing a segfault if we destroy the nfs context/
disconnect the session while the mount_8_cb callbacks for checking the
filehandle for nested mountpoints are still in flight.
