* Create new filters CACHE_OUT_SUBREQ / CACHE_SAVE_SUBREQ which only differ
  by the type (AP_FTYPE_CONTENT_SET-1) from CACHE_OUT / CACHE_SAVE
  (AP_FTYPE_CONTENT_SET+1). This ensures that subrequests to non local
  resources do not get stuck in the middle of the road with the contents
  only written to the temp file, because CACHE_OUT_SUBREQ / CACHE_SAVE_SUBREQ
  are inserted *before* the SUBREQ_CORE filter in the filter chain.

fe80::/16 is for link-scope link-local addresses in IPv6, they are not
for goign in Listen directives, VirtualHost blocks, or anything like
that, and won't work.

Perform a mass search and replace: 2001:db8 for fe80. 2001:db8 is the
IPv6 documentation prefix. See RFC3849 for more details.

Do not check the value of r->handler.

This allows the use of SetHandler for an entire directory, and since we already check via the stat structure if this is a directory, there is no reason for this extra check, which causes a regression since 1.3.
