We only want to load a temporary rules file for processing if the
current app is debuggable or if adb is running as root. The logic to
do this is a bit less than straightforward to read and we don't
currently log the values to help make it clearer (though we know they were
both 'false' to return early). This change helps make the code a bit
easier to read and adds some logging that helps make reading the logs a
little easier too.

Make Nat464Xlat talk to netd directly instead of through
NetworkManagementService. The methods in NetworkmanagementService
don't really provide any value: since the only thing they do is
call into netd, we might as well have the callers talk to netd
directly,
In order to do this, pass INetworkManagementService and INetd to
the NetworkAgentInfo constructor, and update callers appropriately.

Add dummy implementations for status, error and finished callbacks.
Next step: wire these up end-to-end; change Shell's listener to be
BugreportManager.BugreportListener, and make it communicate with the
native service explicitly through the new system api.

The API is mostly implemented; except for hooking up the listener
and handling an already running bugreport.
BugreportManager is the handle to the new API exposed to apps.
Generating bugreports requires root privileges. To limit the footprint
of the root access, the actual bugreport generation in Dumpstate binary,
is accessed as a oneshot service and dies after it finishes
running.
System server accesses Dumpstate via a binder interface since it does
not have root privileges.
Starting a oneshot service is done via setting a system property, which
needs to be done from system server. BugreportManagerService is the
new system server service that does this. BugreportManager calls into
BugreportManagerService via a binder interface, since the former is in
the app's process.
Both app to system server as well as system server to native service
calls are via implementations of IDumpstate binder interface.

This change is the main check in for the historical app op feature.
The idea is to store a historical data about past app op rejections,
accesses, and durations per op for any UID state indefinitely.
Keeping all operations on record is not practical as app ops are
very frequently performed. To address this we are storing aggregated
data as snapshots where we store for every UID and its packages
how many times each op was accessed, rejected, lasted as an aggregate.
To allow history scaling indefinitely we are taking a logarithmic
approach with only the most recent state stored in memory and all
preceding state stored on disk. State on disk is stored in separate
files where each preceding file, i.e. for an older period, would
cover X times longer period with X number of snapshots covering
X times longer period. Initially X is ten but can be tweaked. For
example, the first file could contain data for ten days with daily
snapshots, while the file for older period would have data
for a hundred days with snapshots every ten days, etc.
The implementation is optimized for fast history update and no impact
on system runtime performance and minimizing memory footprint. We
are lazily persisting state to disk on a dedicated thread as this is
slow. We are also reading the relevant historical files on a query
as this is very rare as opposed to state updates.
The base snapshot interval, i.e. snapshot time span, in the initial
iteration and the logarithmic step are configurable. These can be
changed dynamically and the history would be rewriten to take this
into account.

Introduce a new range of app-zygote isolated UIDs, [90000..98999].
For each app that uses an application Zygote, allocate a range of
100 isolated UIDs. The application Zygote for an app will get a
UID out of that range, and all other children that are forked
from that zygote will get a UID from the same range.
Bug: 111434506
Test: app Zygote and its children run in the new range of
isolated UIDs (with SELinux disabled). New set of
tests for UID allocators pass.
Change-Id: I7a6883a5ddb95683932c93ea77f4e52d8f37fa4f
When an application has requested isolated services to be spawned
from an app zygote, we need to spawn the app zygote itself, and then
ask it to fork an isolated service.
The application zygote currently only creates the class loader, and
doesn't do much else. We keep track of the isolated services that
use the app zygote, and when the last isolated service goes away,
we stop the app zygote itself (after a timeout).
The app zygote itself runs with the app's UID and under the app
seccomp filter. That last one is too restricted, so this currently
only works with SELinux disabled.
Future CLs will add an application callback for preloading.
Test: start multiple isolated services with useAppZygote="true",
verify app_zygote starts, services start as a child of
app_zygote. Stopping all services stops app_zygote as well.
