Merge r1532816 from trunk:

Interpolation worked within the scheme portion of URLs for
ProxyPass and ProxyPassReverse until a fix to apr_uri_parse()
in APR-Util 1.5.2 closed the hole that had previously allowed
the necessary {} characters within the scheme.

Lack of support for interpolation within the scheme will be a
permanent limitation.

The mod_proxy documentation is updated to provide an alternate
configuration solution.

WinNT MPM: Exit the child if the parent process crashes or is terminated.

Submitted by: Oracle, via trawick

The original modification was made some years ago for Oracle HTTP Server
by an Oracle employee.  trawick made additional changes for style and
for trunk/2.4.x changes.

Follow up to r1526666:

Use SYNCHRONIZE instead of PROCESS_ALL_ACCESS because

a. it is sufficient
b. it avoids an issue where PROCESS_ALL_ACCESS is larger on
   newer SDKs, resulting in a run-time error when running on
   older Windows
