Fix 32-bit MAXOFFSET_T definition

Browse Source 
Having MAXOFFSET_T defined to 0x7fffffffl was artificially limiting
the maximum file size on 32-bit systems.  In reality MAXOFFSET_T is
used when working with 'long long' types and as such we now define
it as LLONG_MAX.  This resolves the 2GB file size limit for files
and additionally allows zvols greater than 2GB on 32-bit systems.

Closes #136
Closes #81
