PR60009: RewriteRule local prefix checking update

  *) mod_rewrite: When a substitution is a fully qualified URL, and the 
     scheme/host/port matches the current virtual host, stop interpreting the 
     path component as a local path just because the first component of the 
     path exists in the filesystem.  Adds RewriteOption "LegacyPrefixDocRoot" 
     to revert to previous behavior. PR60009.

allow users to workaround the over-agressive backreference
escaping by selecting the characters to escape. 



add BNP flag to give control to the user on whether a space ' ' in
an escaped backrefernece is decoded to a + (default) or %20. Useful
if your backreference isn't going into the query string.

ab: don't call malloc_init for OpenSSL 1.1.0

Patch by rjung.

The 1.1.0 compatibility macro for OpenSSL_malloc_init() causes problems
when mixed with procedure linkage stubs with some toolchains (e.g. GCC).
OpenSSL's malloc implementation doesn't recognize that the PLT stub
points back to it, which leads to infinite recursion.

Since the 1.1.0 documentation states that calling this function
explicitly is no longer necessary except "in certain shared-library
situations"(?), get rid of it.

Evaluate nested If/ElseIf/Else config sections

It has been reported multiple times that nested
If/ElseIf/Else sections are not evaluated but
silently ignored.

This patch adds a simple recursion to the ap_if_walk
logic in order to allow arbitrary nested configs.
The overhead seems negligible compared to the actual
version of the ap_if_walk, but more expert feedback
is surely needed since this code gets called for every
HTTP request.

Tests are going to be added to t/apache/if_sections.t
