executable status of segments instead of detecting the main text segment

obreak() and is required for correct operation of that function
on 64-bit PowerPC systems. The previous behavior was apparently
required only for the Alpha, which is no longer supported.

enabled. Basically most of the operations were incorrect causing
bad sacks when you enabled nr-sack. The fixes range across
4 files and unifiy most of the processing so that we only test
nr_sack flags to decide which type of sack to generate.
Optimization left for this is to combine the sack generation
code and make it capable of generating either sack thus shrinking
out a routine.

and modify the BEGEMOT-PF-MIB to add support for IPV6 address' statistics in the PF
tables via pfTablesAddrNetType and pfTablesAddrNet. While here, upgrade the
pf_tree.def file to the new format that includes enumerated values. Also make sure
to return SNMP_ERR_NOSUCHNAME for ALTQ objects, if ALTQ is disabled, so that the agent
will know to skip the pfAltq subtree when servicing GETNEXT requests from SNMP clients
(otherwise snmpwalk on begemotPf would stop at the pfAltq subtree with bsnmpd returning
SNMP_ERR_GENERR).

First, we compare mode table data against minimum value. If the mode table
does not make sense, we set the minimum in the mode info. When we actually
set the mode, we try VESA BIOS function and compare it against the previous
value. If it makes more sense, update the information.

This patch fixes that leak.

mapping_array expansion would break. Basically
once we expanded the array we no longer had both
mapping arrays in sync which the sack processing code depends on.
This would mean we were randomly referring to memory that was probably
not there. This mostly just gave us bad sack results going back to the peer.
If INVARIENTS was on of course we would hit the panic routine in the sack_check
call.
We also add a print routine for the place where one would panic in
invarients so one can see what the main mapping array holds.
