Kasper Brand came across a flaw in the current implementation when CRL

Kasper Brand came across a flaw in the current implementation when CRL
information - i.e.  SSLCARevocationFile/SSLCARevocationPath - is set
on a per-vhost basis (don't know how much sense it makes to have
non-global CRLs, but anyway...).

The attached patch (47B2B1A7.1060009@velox.ch on httpd-dev) addresses
this issue, and it also improves the logging behavior for an SNI
enabled configuration (previously some of the messages would
always go to the first vhost, or wouldn't appear at
all, depending on the LogLevel of the first vhost).
