Running "configure --enable-utils" _disables_ compilation/installation of
utils (and vice versa) while omitting the --(en|dis)able-utils option auto-
enables utils.
This patch fixes the logic when the option is given on command line but
keeps utils build enabled when the option was omitted.
NFSv4 support.
lockf() support (NFSv4 only).
fcntl() support for locking (NFSv4 only).
Add CMake support.
URL arguments to select NFS version.
URL argument to set nfsport. This allows NFSv4 to work for
servers without portmapper support.
URL argument to set he mount port.
NFSv4: use getpwnam to map NFSv4 (Ganesha) when passing uid/gid
as a user/group name insead of as a uid/gid.
Added nfs-fh: a simle utility to print the filehandle for a nfs file.
Win32 build fixes.
Add a new open2() function that takes a mode argument.
Add a testsuite for libnfs.

It didn't fail if pwd.h is missing because #includes must be seperated with a newline, a comma won't work.
The compile works anyway because the "struct passwd *pwd" implicitly declares an anonymus struct type "passwd"
and using an undeclared function is an implicit function declaration. Here's the output of configure in that case:
configure:13381: checking whether getpwnam() is available
configure:13396: i686-w64-mingw32-gcc -c -I/home/daniel/fsetmp/dokany/src/dokan_fuse/include/ -I/home/daniel/fsetmp/dokany/src/dokan_fuse/include/ conftest.c >&5

configure:13396: $? = 0
configure:13403: result: yes
Some nfsv4 servers return a user/group name in the attributes instead
of a uid/gid number. At least for the "nobody" user.
For those, try to use getpwnam() where available to map the string back
to a uid/gid or return uid/gid==65534 (common value for nobody)
if not available or failing.

The main changes since 1.11.0:
BUGS
====
Fix NULL pointer crash in nfs_link().
Clamp read/write size for servers (Ganesha) that offer very large io sizes
instead of failing to connect to the export.
Tell the server to commit all data to stable storage when we close files.
Double free fix: don't call rpc_free_pdu() after rpc_queue_pdu() failure.
Fix for memory leak in rpc_allocate_*().
Fixes to build nfs-ls and nfs-cp on win32.
Abort the mount process correctly if MOUNT/MNT returns error or is cancelled.
Fix memory leak in error path in nfs_create_2_cb().
Fix leak of rpc->inbuf if we destroy the context while we still have PDUs
in flight.
FEATURES
========
Add O_NOFOLLOW support for nfs_open()
Add a new mkdir2 command that also takes a mode argument.
Add a new readlink2 command that avoids having to preallocate the buffer.
Add support for RPC timeouts for both the sync and async interfaces.
Build fixes for Mingw and Cygwin
Update README to document two new Windows builds
Use SOCK_CLOEXEC for the sockets
Make rpc_set{g|u}id() public
Performance optimization: socket: Batch pdu read in rpc_read_from_socket
Low level support for NFSv4 and some examples
Support for building RPC servers

The configure.ac script was erroneously including -lws2_32,
i.e. the winsock2 library. Cygwin is a full POSIX environment
and does not need the winsock2 functionality as it supplies its
own POSIX compatible sockets.
Including -lws2_32 caused getnameinfo to fail with error 10093
(WSANOTINITIALISED). This usually means that the Winsock
WSAStartup function has not been called. Calling WSAStartup is
not necessary for Cygwin programs and in fact should be avoided.
Those tests are compile-time and link-time checks, and running the
resulting programs is not needed or even helpful. This fixes the
Windows cross-build, which previously failed because SO_BINDTODEVICE
was assumed to be available.
- 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)

`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`.
The biggest changes in this release are:
- Fix a leak where we leaked one rdpe_cb_data structure on each open_dir()
- Make building the utils optional
- Android: the correct define is __ANDROID__ not ANDROID
- Win32: Use _U_ instead of ATTRIBURE((unused))
- Win32: Fix nfs_stat declaration for Win32
- Various fixes for mingw builds
- Make rpc->connect_cb a one shot callback and improve documentation
- Remove the FUSE module. It now lives in its own repo
- Fix POLLERR/POLLHUP handling to properly handle session failures and to
try to auto-reconnect

- Disable multithreading in fuse_nfs
- Add -Wall and -Werror compiler flags (and fix issues found by it)
- Add nfs-cat utility
- Switch to using nfs_[f]stat64 instead of the deprecated nfs_[f]stat call
in all examples
- If the server does not return any atttributes for entries in READDIRPLUS
then try to fetch them using lookup instead.
- Reconnection fixes
- Enforce the max pdu size and add sanity checks when reading PDUs from
the socket.
- Stop using ioctl(FIONREAD) to find out how many bytes to read, and treat
0 as an indication of a problem. Some applications call their POLLIN handlers
spuriosly even when there is no data to read, which breaks this check in
libnfs.
- Add basic support to do logging.

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?)

- Auto-traverse mounts. With this option (default to on) libnfs will
autodiscover and handle any nested submounts.
- Remove nfs_get_current_offset. Applications should use seek instead of this function.
- Add umask() support.
- Change set_tcp_sockopt() to be static.
- Android fix for nfs-ls
- Make S_IFLNK available on windows.
- Fix a use after free.

Wed Mar 19 2014: Version 1.9.3
- Add O_TRUNC support to nfs_open()
- Add a simple but incomplete LD_PRELOAD tool
- Fixes for some memory leaks and C++ compile support
- Make ANDROID default uid/gid to 65534
- Allow the READDIRPLUS emulation to still work if some objects
in the direcotry can not be lookedup (NFSv4 ACL denying READ-ATTRIBUTES)
- Have libnfs retry any read/write operations where the server responds
with a short read/write. Some servers do this when they are overloaded?
- Use _stat64 on windows so file sizes become 64bit always.
- Increase default marshalling buffer so we can marshall large PDUs.
- RPC layer support for NFSv2
- Win32 updates and fixes
- Add URL parsing functions and URL argument support.
- New utility: nfs-io
- nfs-ls enhancements
- RPC layer support for NSM
- Add example FUSE filesystem.
- Minor fixes.
I need this to detect that we have (almost) version 1.9.0 in qemu,
but I think we should do some more testing before releasing 1.9.0.

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
