Log Message:
-----------
Reduce PANIC to ERROR in several xlog routines that are used in both
critical and noncritical contexts (an example of noncritical being
post-checkpoint removal of dead xlog segments). In the critical cases
the CRIT_SECTION mechanism will cause ERROR to be promoted to PANIC
anyway, and in the noncritical cases we shouldn't let an error take
down the entire database. Arguably there should be *no* explicit
PANIC errors in this module, only more START/END_CRIT_SECTION calls,
but I didn't go that far. (Yet.)
