The Revision object needs the Title to determine the default content model.
Providing the Title explicitely wherever possible avoids an extra database
lookup. Most importanlty, this fixes fatal errors that ocurr when the
database lookup fails due to slave lag or transaction state.

Undeletion was broken twice:
1) originally, it failed silently, restoring revision entries with
the wrong number in rev_page.
2) I789e45bd restores an overly zealous sanity check, causing
undeletion to fail with a fatal error.
This change fixes both issues.

This is a follow-up to I9db228c3 fixing an issue with undelete:
Page ID 47009 mismatches the ID 47010 provided by the Title object.

With $wgContentHandlerUseDB, Revision needs access to the page's Title
object to determin the page's default content model. This apparently
failed in production for newly created pages (supposedly because of
some complication with database transactions or master/client setup).
This change makes WikiPage::doEditContent pass the Title object
directly to the Revision to avoid any database issues. This also
gets rid of a pointless database read.

The introduction of the ContentHandler caused quite a few functions and hooks to
become deprecated. Usage of these has been removed in core, but is still present
in extensions. Extensions should be fixed after ContentHandler has settled in a
bit, but for now we need a way to silence the warnings.

Make userWasLastToEdit a static method in the Revision class, so it can be
reused by extensions, etc.

Revision::getContent must return a cloned instance of the Content object
if the Content object is mutable to avoid confusion.
Content::copy is used to achieve this, which is specified to return $this
for immutable Content.

This introduce the syntax from aliased table names for aliased field
names into the abstract database layer:
array( 'alias' => 'field' ) gives 'field AS alias'
This patch also includes changes to query pages, api and some more
places to show, how the new syntax looks in "production".
This allow us to remove the "AS" for Non-PostgreSQL databases, if we
want that.

* Replaced WikiPage::DATA_FROM_* constants with IDBAccessObject ones.
* Renamed IDBAccessObject constants a bit for visual consistency.
* Removed AVOID_MASTER parameter and replaced calling instances with READ_NORMAL.
Instead of getting page_latest from the master and the revision from a
slave, just get it all from the master in one RTT. Most callers used
AVOID_MASTER (and now READ_NORMAL), so this case is barely hit anymore.

* The main Revision functions now allow various QoS and locking flags.
* Added tiny DBAO interface add made Revision implement it.
Since a lot of objects will need (or have) the same functionality.
* Use "self" keyword in Revision class consistently.
* Made Revisison::newFromConds() private.

The content model is stored as a varbinary(32), the format
as varbinary(64).
If the standard model resp. format is used, null is written
to the database instead of the actual id, saving space.

Moving function getParentLength from SpecialContributions to Revision
and use it in the list module. The size of the parent is selected by a
batch, like the special page.

Otherwise MW will throw an exception with the message "LinkCache doesn't currently know about this title"
when accessing redirect or len items of these Title objects, e.g. in Special:RevisionDelete.

Revision::getTitle will make a query against slave to load the title on
demand. But when there is a slave lag, the slave does not know the new
revision id and the caller gets null back

Seen on Special:NewPages: Linker::revComment is calling
Revision::getTitle, but the revision object has no id set.
This is another way to avoid a query per non-empty comment on
Special:NewPages, see gerrit 9003
