Help cherry-pick for fix to TRQ-2118.
Modified patch for TRQ-2118 to make it so TORQUE will compile
with --enable-munge-auth. Removed #ifndef MUNGE_AUTH conditionals
to simplify code.
Fixed a problem where the stack size was not getting set
when allocating new threads resulting in very large amounts of
memory allocated for pbs_mom and pbs_server with the ulimit -s
size got large. (i.e. 300000). TRQ-2283
