The bug was introduced when the inserting of the HTTP_HEADER filter was
moved to the insert_filter phase. This change made it possible for
AP_FTYPE_HTTP_HEADER filters to run before HTTP_HEADER (and have an
effect), but at the same time left the filter stack empty when errors
occurred before the insert_filter phase.

The patch adds a check to ap_die() to make sure the basic filters are
present, and adds them if they are needed. ap_die() previously assumed
the filter stack would be ok during an error condition, which is not
necessarily the case.
