[sql] Static helper to delete database and all associated files.

[sql] Static helper to delete database and all associated files.

Not all of the ad-hoc file_util::Delete() cases handle -journal, and
if -wal was added all of them need to be tracked down.

I hung it on sql::Connection because the path should correspond to that passed
to Open().  But possibly this should be sql::DeleteDatabase().

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.

Brett, I think that means I need to fallback on you for the LGTM.

Brett?  Click the little "Quick LGTM" button, please.

Greg, Brett is apparently AWOL.  I've been abusing Erik for sql/ reviews on
another front, so I need a different victim for a committer LGTM.  Thanks.
