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]

commit 1c1e09a completely broke connects for non broadcast
traffic since it forgot to copy the server address into
the socket_storage struct.

NFS servers can respond to requests in any order, and they do. In our
tests there is also some clustering to the responses; it could be
because eg. requests are served synchronously if the data is in the cache.
Introduce a hash table so that we are able to find the pdu quickly in
all cases, assuming random distribution of the responses.
When making many concurrent requests (as is likely in any performance
criticial application), the use of SLIST_REMOVE and SLIST_ADD_END are
a severe bottleneck because of their linear search.
I considered using a double-linked list but it was unnecessary to
allocate the additional memory for each list entry.
Instead, continue to use a single-linked list but retain:
* a pointer to the end of the list; and
* a pointer to the previous entry during a linear search.
The former would makes append operations O(1) time, and the latter
does the same for removal. We can do this because removal only happens
within the linear search, and there is no random access to the queue.
This adds basic IPv6 support to libnfs.
Since libnfs currently only support PORTMAPPER protocol up to version 2
the IPv6 support only works if the server runs Both MOUNT and NFS protocols
on the same ports for IPv6 as for IPv4.
To get full IPv6 support we need to add support for PORTMAPPER version 3
and use it for discovery when using IPv6
These were uncovered by the previously added __attribute__((format(printf))).
Emacs also removed trailing whitespace while at it.

This is mainly needed when having to track and control the file descriptors that are used by libnfs, for example when trying to emulate dup2() ontop
of libnfs.
This allows indirect support for a configurable connect timeout.
Linux uses a exponential backoff for SYN retries starting
with 1 second.
This means for a value n for TCP_SYNCNT, the connect will
effectively timeout after 2^(n+1)-1 seconds.
Example:
examples/nfs-ls nfs://10.0.0.1/export?tcp-syncnt=1

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.
and try to bind to a system port in case the user is root or the
binary has the CAP_NET_BIND_SERVICE capability
this removes the need to use 'insecure' on the server
