Backport r1173851, r1173866, r1173868 and r1173878.

r1173851 by rich:
- Fix wildcard ssl handling. We now correctly handle wildcards, rather than
  using shell globs. This removes the same issue as QTBUG-4455.  In addition,
I've fixed http://www.westpoint.ltd.uk/advisories/wp-10-0001.txt for konqueror.

r1173866 by whiting:
QString::lower doesnt exist, changed it to QString::toLower to make it build
again

r1173868 by ahartmetz:
This started out as a build fix that was already committed.  While I'm at
it make more things const and do hostname case normalization in the hostname
matching function itself so it's less error-prone (I might reuse that function
elsewhere).  Also make it static; less symbols in the resulting binary and make
it clear that it uses no class members.

r1173878 by ahartmetz:
SVN_SILENT improved comment about hostname matching
