Subject: Don't test file existence in adblock, katze_mkdir and check download status
X-Git-Url: https://spindle.queued.net/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1c424106f10f7bf8783bc3e4889654b43d5509b6;p=midori

Don't test file existence in adblock, katze_mkdir and check download status

It is enough to see if g_fopen fails, thus we don't need g_access
to test file existence additionally.

katze_mkdir_with_parents is optimized for existing folders.

We need to check the status, to see if file downloads are finished.

For Windows, we need to use g_strndup instead of strndup.
