IPV6: Add basic IPv6 support
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

New version: 1.9.3
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?

fix possible wrong cast to 32-bit unsigned
when calculation the max_offset the (unsigned) leads to a cast
to a 32-bit unsigned integer depending on the platform. as a result
we update the max_offset everytime when it grows beyond 2^32.
this leads to a wrong return max_offset value if the callbacks
are received out of order.

Dont check for NFS errors in the LOOKUP during READDIRPLUS emulation
On servers with extended attributes, a server copuld be set up to
deny READ-ATTRIBUTES for the libnfs user.
This means that READDIRPLUS will no longer work since it will need to
stat() and thus READ-ATTRIBUTE in order to prepare the response.
Libnfs has READDIRPLUS emulation for the cases where this command fails
by switching to old READDIR to scan all the file names and then a LOOKUP loop for getting the file attributes.
Most of the time the purpose for this emulation is to handle the case where the server simply does not support READDIRPLUS at all, which sometimes is the case for embedded systems with userspace nfs servers.
In this case, where files just have READ-ATTRIBUTE deny for the libnfs user,
this will also fail and trigger the fallback to READDIR + LOOKUP-loop.
If the LOOKUP fails for this loop, then just ignore trying to update the attributes we have for this object, but do not fail the actual READDIRPLUS emulation.
This addresses a permissions issue reported by a XBMC user in issue #60
Spotted by clang analyzer.
This introduces another allocation to create a copy of the target path
of a rename in case it needs to be reported via rpc_set_error - it might
be a better idea to avoid the allocation and have a slightly less informative
error message?

Add support for O_TRUNC with nfs_open()
O_TRUNC will attempt to truncate the file when opened with O_RDWR
or O_WRONLY.
Normal posix open(O_RDONLY|O_TRUNC) is undefined.
libnfs nfs_open() only uses the O_TRUNC flag when used in combination with either O_RDWR or O_WRONLY.
When O_TRUNC is used together with O_RDONLY libnfs will silently ignore the O_TRUNC flag.
Libnfs nfs_open(O_RDONLY|O_TRUNC) is thus the same as nfs_open(O_RDONLY)
