hrStorageSize and hrStorageUsed are 32 bit integers, reporting a fs
size and usage in hrStorageAllocationUnits. If the file system has
more than 2^31 allocations it can not be shown correctly and the
meters are useless.

In such cases follow net-snmp behaviour and increase
hrStorageAllocationUnits so the values fit under INT_MAX.

Spelling fixes for usr.sbin/

Reduce the memory requirements for the tables by (1) using malloced strings
instead of maximum sized arrays embedded in the table structures and (2)
using pointers to constant oids instead of copying the oid into each
table structure. This also fixes indexing in the case when a string used
for indexing is longer than the maximum size allowed in the MIB.

Forced commit because I lost the commit message in the previous commit:

This is the implementation of the HOSTRES MIB that was developed by
Victor during SoC 2005 with some stylification by philip@ and harti@.
