This helps the accounts editor fit in narrow screens.

This avoids using wide hardcoded margins and instead adapt to the
available size.

This implements the new designs, uncluttering the header bar to allow
the mobile mode. It's already possible to reply or forward from a
specific message.

Navigate forward when activating a folder and when activating a
conversation while the window is folded.

This will simplify navigation when folded.

This will simplify navigation when folded.

This allows moving back to previous panes.

This keeps the swiping state of the leaflets in sync.

This will be used to sync the swipe state of the leaflets.

There is no way to navigate into the app, but it's a start.

Bind each pane's elements minimum size requests via size groups.

This will be used to sync requests of the panes.

Split it into a folder header and a conversations header. This is needed
to properly split the 3 panes.

Fixes https://gitlab.gnome.org/GNOME/geary/issues/442.

Move it at above the conversations but not above the folders. This is
needed to properly split the 3 panes.

This won't be needed to save horizontal space when using HdyLeaflet, and
it would make porting to it harder.

This is needed to replace GtkPaned by HdyLeaflet. This breaks syncing
the size of the headerbar with the rest of the window, it will be fixed
in a later commit.

Application.Controller: Permit notifications when no main window

Closes #716

See merge request GNOME/geary!420

If there's no main window, the app must be running hidden, so
notifications should be sent.

Fixes #716

The regex line in this javascript was > 256 characters, which triggers
the following warning from debian's "lintian" source-checking tool:

    https://lintian.debian.org/tags/source-is-missing.html
    https://lintian.debian.org/tags/source-contains-prebuilt-javascript-object.html

This offers no functional change, but avoids some needless warnings
going forward.

Problem report memory fixes

See merge request GNOME/geary!418

Take a copy of extant log records when constrcuted so that newer records
can be dropped while the problem report still exists. This uses more
memory, but limits unbounded memory growth while any log reports
still exists.

Clear logs iteratively to avoid recursively freeing all log messages on
the stack at once.
