Ok - this is the 64 bit widening check in. It changes the configure

to check for stat64 and friends, and then changes much of Samba
to use the data type SMB_OFF_T for file size information.

stat/fstat/lstat/lseek/ftruncate have now become sys_stat etc. to hide
the 64 bit calls if needed.

Note that this still does not expose 64 bit functionality to the
client, as the changes to the reply_xxx smb's are not yet done.

This code change should make these changes possible.

Still to do before full 64 bit-ness to the client:

fcntl lock code.
statfs code
widening of dev_t and ino_t (now possible due to SMB_DEV_T and SMB_OFF_T
types being in place).

Let me know if wierd things happen after this check-in and I'll
fix them :-).

Jeremy.
