[PATCH] Use dedicated Windows heap for each apr_allocator_t

Hi,

Please find attached patch that adds an option
(APR_ALLOCATOR_USE_WIN32_HEAP) to use dedicated Windows heap for each
apr_allocator_t. Using dedicated heaps for APR allocator should reduce
memory fragmentation for mutli-thread application like Apache HTTPD on
Windows.

Log message:
[[[

  (apr_allocator_destroy): Destroy dedicated heap if
