Merge r1788032, r1788033, r1783764, r1707512, r1783770 from trunk:

Save a few bytes in the conf pool.

'push_item' and 'add_alt' already duplicate their parameters, so we can safely use the temp_pool here.

Use 'ap_cstr_casecmp' to simplify code.

Remove useless case. We know that to can not be NULL at this point.

Follow up to r1772812: update APLOGNO().

* modules/ssl/ssl_engine_kernel.c: Constify the ssl_hook_Fixup_vars array itself.


winnt/service: each log message should use its own APLOGNO.
