Merge r1932996 from trunk:

apr_cstr.h: Fix inclusion of other APR headers

Use double quotation marks, not angle brackets, when including other APR
headers from apr_cstr.h.  This matches what all the other APR headers do
and avoids tripping certain static analysis tools.

Submitted by:	Dag-Erling Smørgrav <des@des.dev>

This closes #70
