Callers with INTERACT_ACROSS_USERS_FULL permission can now observe content
for a given user's view (and can notify content uri changes targeted to a
specific user). An observer watching for UserHandle.USER_ALL will see all
notifications for the given uri across all users; similarly, a notifier
who specifies USER_ALL will broadcast the change to all observers across
all users.
The API handles both USER_ALL or USER_CURRENT, and explicitly forbids
any other "pseudouser" designations.
This CL also revs the Settings provider to notify with USER_ALL for
changes to global settings, and with only the affected user's handle
for all other changes.

Various wifi settings that are explicitly defaulted did not get their
default code properly converted to refer to the correct settings
database table.
A collection of moved-to-Global settings that had not yet been
marked @deprecated in the Secure.* namespace are now so marked.
Also updated the namespace used to refer to wifi settings from the
Wifi Service. These changes are cosmetic, but they do eliminate a
number of runtime log messages.

Oops. Stacked bugs: first, the desired user handle was not properly
being passed from the call() entry point to the database operations;
then on top of that, the client-side cache management was still
looking in the local user's cache for the data, so a request to read
a different user's settings would return the local user's instead if
that key was already known to the local user's cache.
Reads and writes of a different user's settings are now uncached,
so they're relatively much slower. They're rare, however, so this
is not something to worry about unless we encounter a real world
case where it's a significant factor.
This CL also adds a bit of cross-user settings read/write testing
to the existing provider suite. These new tests caught both the
known wrong-user-write bug and discovered the client-side cache
bug, so yay.
Finally, the existing wholesale mutual-exclusion approach would
deadlock in certain circumstances due to the fact that the
settings database creation code might have to call out to the
Package Manager while populating the bookmark/shortcut table,
and the Package Manager would then call back into the settings
provider in the course of handling that request. The synchronization
regime has been significantly tightened up now: now the database
code [which is known to deal with concurrency itself] is allowed
to cope with multiple parallel openers of the same db; this
allows the settings provider to avoid calling out to other parts
of the system even implicitly while its internal lock is held.

Now we can bind to just one instance of DCS, instead of requiring
one-per-user. This also means we can operate on otherwise-stopped
users.

1. The core accessibility settings required for a blind user to use
the device should not be overwritten on restore. There could have
been enabled via a global gesture from setup wizard, hence the
user definitely needs them. Restoring disabled values for these
settings render the device useless unless sighted help is sought.

Also tidy up the bookkeeping for a few settings that were earlier
moved to Global without the redirect tables being fixed up.

Also correct some now-misleading terminology in a permission-check
log message, and fix a bug in which a system component trying to
write to a secondary user's settings would wind up writing the
owner's settings instead.
