slot: use the default mount location when switching to a mount root

Add a new flag to signal that we really want the default mount location
to be loaded if possible. This way we can still get to the mount root
e.g. by going up or typing it directly in the location bar, but the
default location between sidebar mounts and using Connect to Server will
be the same.

toolbar: set action tooltip on the toolbar button

Since we don't use a GtkToolButton directly, we need to propagate the
action tooltip manually to the GtkButton.

slot: ensure we're back from an active search when changing location

We used to keep track of the search active state using the state of the
search toggle button; unfortunately, the button is per-window,
so its active state will also be synchronized when switching tabs.
This will cause a non-search slot that becomes active following a tab
switch from a search slot to think its search just became inactive, and
will then change its location to the default ($HOME).

Fix the bug by keeping an additional state per-slot for whether there's
an active search.

places-sidebar: make sure to pre-select the active item on construction

Ensure the current window URI gets selected in the sidebar also when
it's already set on the window at construction.
At the same time, move the sidebar construction from
nautilus_window_show() to nautilus_window_constructed().

tracker-engine: treat the search string as a sentence for FTS match

Or the hyphens will be treated as NOT operators instead of word breaks,
which will prevent results from being returned.

slot: rework query editor visible state synchronization

Fix a case where entering a directory from the search results would not
take the query editor down, and refactor some code around the state
synchronization between the two objects.
slot: save return location before clearing query editor state

Or we'll always return to $HOME.
window: don't remember focus widget when switching search visible

The workaround we need to make to focus the entry on-the-fly and
synchronizing the visible state with the toolbar button badly clash with
the focus widget state saving mechanism we have in place.
We end up calling remember_focus_widget() on the newly-focused
search entry in certain circumstances, so we end up restoring the focus
on the (then hidden) search entry, which will then eat key events while
invisible.

Sidestep the issue entirely by just focusing back the view when closing
the query editor.

view: ensure Trash action is visible when setting sensitivity

We will set the visibility of the action to FALSE when we go to a
location that supports deletion but not trashing, but we fail to restore
it to TRUE when we go back to a directory that supports trashing.

bookmark: don't try to connect to a vanished NautilusFile

When the file watched by the bookmark is trashed or deleted, record the
fact in the object state; later, when checking whether the URI exists,
use that information to avoid connecting to a vanished NautilusFile.

Currently, we will hit an assertion later for unmounted remote volumes;
this bug wasn't present in master and the cherry-pick for commit
231f0b074da973f2c0b69513b743548810d4e716 introduced this regression.
