Make BookmarksProvider set inline_autocompletion and
allowed_to_be_default_match.

This has no effect unless bookmarks are made to score more highly (and
so they'll empirically end up as the top-scoring match).

Includes unit tests.

In the process, fix whether trailing slashes are omitted, for consistency
with other providers.  This will reduce jank if bookmarks are
ever inlining.  Tested interactively.

Likewise, fix whether http:// is omitted.  Tested interactively.

Also, refactor a common piece of code from ShortcutsProvider
to URLPrefix.

Likewise, make a protected function in HistoryProvider public
for use elsewhere.  Mark it static (because it can be).

Also, fix a PreventInlineAutocomplete bug in ShortcutsProvider.
Adds a test for this.  These tests fail before this change.

Also, fix a PreventInlineAutocomplete bug in BuiltinProvider.
Didn't bother adding a test for this because no tests examine
inline_autocompletion here and I didn't want to bother adding
some just for this minor change.  Tested it interactively.
These tests fail before this change.
