Makes initing Places services cheaper, by delaying the connection creation to the first time
it's actually needed.
Same way, delays reading the bookmark roots at the first time they are requested.
Deprecates the concept of lazy observers, since they are no more needed, we can just use addObserver.
Simplifies the startup path: always sends "places-init-complete" (both as a category and a topic) when
the connection starts and adds a "locked" database state when we can't get a working connection.
Makes PlacesCategoriesStarter register for the new category, since it's cheaper than being a bookmarks
observer.
Fixes a couple race conditions in keywords and expiration due to new startup timings.
Removes a test in test_keywords.js that is no more easily feasible, since it'd requires a pre-build
places.sqlite that should be kept up-to-date at every version.

Instead of opening and closing the favicons database at every startup to check whether
it's corrupt, just use the ATTACH DATABASE query result to achieve that.
Also avoid replacing places.sqlite in case of non-fatal errors during the connection
initialization.

This patch moves favicons blobs to a separate database names favicons.sqlite.
The dabatase is then ATTACHED to the main Places connection, so that its tables
can be used as if they were all part of the same database.
The favicons.database contains 3 tables:
1. moz_pages_w_icons
This is the way to join with moz_places, through page_url_hash and page_url.
We are not using the place id to avoid possible mismatches between places.sqlite
and favicons.sqlite. This way the database is "portable" and reusable even
if places.sqlite changes.
2. moz_icons
Contains icons payloads, each payload can either be an SVG or a PNG. These
are the only stored formats, any other format is rescaled and converted to
PNG. ICO files are split into single frames and stored as multiple PNGs.
SVG are distinguishable through width == UINT16_MAX
In future the table will also contain mask-icon color for SVG and average
color for PNGs.
The fixed_icon_url_hash is "fixed" to allow quickly fetch root icons, that
means icons like "domain/favicon.ico" that can also be reused for any page
under that domain.
3. moz_icons_to_pages
This is the relation table between icons and pages.
Each page can have multiple icons, each icon can be used by multiple pages.
There is a FOREIGN_KEY constraint between this (child) table and icons
or pages (parents), so that it's not possible to insert non-existing ids
in this table, and if an entry is removed from a parent table, the relation
will be automatically removed from here.
Note though that removing from the relation table won't remove from the
parent tables.
Since the relations are now many-many, it's no more possible to simply join
places with the icons table and obtain a single icon, thus it's suggested that
consumers go through the "page-icon" protocol.
The migration process from the old favicons table is async and interruptible,
it will be restarted along with the favicons service until the temp preference
places.favicons.convertPayloads is set to true.

This aims at speeding up DELETE FROM moz_places like queries.
The primary reason of slowness is the FOR EACH ROW trigger that takes care of updating the moz_hosts table when places are removed.
Unfortunately Sqlite doesn't support FOR EACH STATEMENT triggers, that means the trigger will hit multiple times for pages in the same host.
The patch introduces an additional temp table to accumulate hosts during a delete, then a trigger takes care of updating moz_hosts only once per touched host, rather than once per removed place.

The problem is due to sanitization happening too late in the shutdown cycle.
The Sanitizer depends on Places shutdown, that recently moved to async shutdown.
That change caused shutdown to happen completely at profile-before-change, unfortunately
during that phase it's impossible to predict which services are already shutdown.
The patch restores the previous Places shutdown procedure, thus clients are notified
earlier, during profile-change-teardown.
Additional meaningful changes:
* Fixes FX_SANITIZE_TOTAL telemetry to properly count total time taken by sanitize.
* Makes each cleanup operation isolated from other errors to try cleaning up as most as possible.
* In case of multiple sanitization sub steps, each step is isolated by a try/catch, the last seen exception is reported upstream.
* Makes FX_SANITIZE_HISTORY actually measure history, not other random stuff.
* Removes TOPIC_SIMULATE_PLACES_MUST_CLOSE_1 since we can now just use profile-change-teardown for shutdown phase 1.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
