Add automatic reconnect after TCP session failure for the sync interface.
...
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.

On OSX and other systems where we have sockaddr_in, SIOCGIFCONF returns a packed list of ifreq structures, so we can not just index them as (struct ifreq *)[i]
...
Instead we have to compute the offset into the buffer for where the next record starts (this offset might or might not be sizeof(struct ifreq)

handle the case where we try a multi-read that is completely beyond the end of file.
...
when a multi-read was completely beyond the end of file, this caused us to invoke the callback with a 'read-count' of <0 which the callback would treat as a failure.
This would then cause the callback to treat the data pointer as an error string and try to use it for nfs_set_error().
Since the data pointer was actually a real binary databuffer and not an error string this would cause the NFS error string to look like it contained garbage data.
In this case, where the multi-read fails to read any data at all since it if fully beyond end of file, make sure to invoke the callback with a read-count of 0

fix crash in mount/export
...
need to check that status is OK before we start dereferencing the 'export' pointers or else we will segv.
this could happen if trying to pull the list of exports from a host that does not have mountd running, or if we can not connect at all to the host.

Add a very subtle bug in nfs_set_error()
...
when nfs_set_error is called with error_string being the result of a lower layer
problem so it is passed as "rpc_get_error()"
This meant that since free that nfs->rpc->error_string before we reference it a few lines further down in the vasprintf(..., error_string,
adn memory corruption triggers.
Valgrind found this, Valgrind rules!

When doping chunked multi-reads of a blob bigger than the max readsize,
...
a read can sometimes span beyond the end of file.
In which case individual smal read chunks beyond the end of file will return OK, 0 bytes of data and EOF==1
For this case, trap when len==0 and ignore these chunks.
Do not update the read-count if / when len is 0.

Add support in read/pread to be aware of the Maximum Read size that the server

When a read/pread operation that is 'oversize' is issued, the read/pread command will internally chop this up into smaller chunsk and send then concurrently to the server.
As replies come back from the server we add the data to a reassembly buffer
and as soon as all replies have been received we invoke the callback and pass the reassembly buffer back to the application.
