In Qt < 5.10 (and also sometimes on Windows), we get extra spaces or newlines
when moving to the end of the document. However, this only happens *sometimes*,
and manual testing confirms that with the current workaround, we actually lose
the last char in the selection.
I'm not sure what's happening there, but instead of making things worse with
the workaround, let's just be a bit less strict with the checking there and
accept both variants... This seems like some Chromium bug we can't do much
about.
If the blacklist is only valid for the completion, the setting should also be
under completion.
This also un-renames history.gap_interval and renames
completion.web_history_max_items.
This adds a new CompletionMetaInfo table which is a simple key/value store.
Thanks to Python/sqlite duck typing, we can use that to store values of any
type, even new ones in the future.
Currently, the only allowed key is force_rebuild, which forces a rebuild of the
CompletionHistory table. This will be needed for a future change.
In ffc29ee043 (part of v1.0.0), a
qute://settings/set URL was added to change settings.
Contrary to what I apparently believed at the time, it *is* possible for
websites to access `qute://*` URLs (i.e., neither QtWebKit nor QtWebEngine
prohibit such requests, other than the usual cross-origin rules).
In other words, this means a website can e.g. have an `<img>` tag which loads a
`qute://settings/set` URL, which then sets `editor.command` to a bash script.
The result of that is arbitrary code execution.

This reverts commit 1956590df84a72c7f9a516e805d01529291fccf8.
Turns out the actual issue wasn't due to *invalid* links - it's with links
which have an unknown scheme.
There's still a change in behavior between Qt 5.10 and 5.11 though: Invalid
links are apparently not passed to acceptNavigationRequest (sometimes?) so we
don't show an error message. Instead, we just load about:blank. However,
Chromium does that too and we can't handle a real click easily, so let's just
ignore that one.
