Separate the decision on whether to log to two separate ones - logcat
and statsLog to allow separate policies.
Also add startLogAll and endLogAll in preparation for an adb command
that will enable/disable logging to logcat every time.

This CL adds two new methods to the IPlatformCompat binder interface for
toggling multiple compat changes at once, and for clearing all the
overrides for a given package name.

Store the reported changes by app and clear the app info on app launch.
This means that changes reported to the system server would be logged
once per app launch instead of once per device boot.

A side effect of CL topic r.android.com/q/topic:bug136256059_attempt2
was that the default MimeMap instance is now loaded eagerly (pre-fork)
regardless of whether any app process ends up using it, whereas
previously it was loaded lazily (post-fork) the first time an app
process used it.
This traded off CPU and memory use post-fork vs. pre-fork. Because it
isn't known / hasn't been proven whether and how many app processes
use that instance, the net CPU and memory impact is not known: if at
least one process makes use of a relevant API, the net impact will be
neutral or positive, or else negative.
Until this can be investigated and undergo system health review, this
CL topic changes the behavior back to post-fork lazy loading of the
default MimeMap instance.

The zygote handles requests by polling on its sockets, and then handling
one request for each active socket. However, it does so by reading from
a socket via a BufferedReader, which means that if multiple requests are
written into the socket before the zygote gets a chance to read them,
the zygote reads multiple requests into its BufferedReader, it handles
one request, and then never responds to the request that's buffered,
leaving its client stuck waiting for a response that will never happen.
For most requests, this can't happen, because the client will wait for a
response to be sent from the zygote before sending another request, but
this isn't true for --boot-completed until this patch.

IsChangeEnabled returns true if there are no installed packages for the

* changes:
MimeMapImpl.createDefaultInstance() -> DefaultMimeMapFactory.create().
Make MimeMap final and introduce MimeMap.Builder.
Move default MimeMap implementation to frameworks.
The class no longer implements MimeMap, so the name MimeMapImpl
no longer made sense.

This is the second attempt to submit this CL. The first attempt
regressed on app startup because RuntimeInit installed the
custom MimeMap from commonInit() which runs post-fork of the zygote,
but that was fixed by installing it pre-fork.
This CL topic moves the default MimeMap implementation to frameworks.
Libcore starts with a minimal implementation sufficient to pass
CtsLibcoreTestCases, but frameworks can inject the real implementation.
Before this CL topic, the data files and logic (MimeMapImpl) were part of
core-*.jar on device; after this CL, they instead live in framework.jar.
Tests from MimeMapTest that check behavior of that default
implementation also move to a non-libcore CTS test.
Planned work for follow-up CL:
1. Make CTS more opinionated, with a plan to assert that all of
the default mappings are present. How exactly the expectated
mapping will be bundled in CTS is still TBD.
2. Add a vendor.mime.types file (defaults to empty) where vendors
can add additional mappings; I plan to make it such that mappings
in that file are parsed last but never override any earlier
mappings, as if each mime type / file extension was prefixed
with '?'.
3. Perhaps enforce that public APIs android.webkit.MimeTypeMap
and java.net.URLConnection.getFileNameMap() behave consistently
with MimeMap.getDefault().

Limit 1 log per app launch as the statd logs as this is spamming logs.

Until recently, I and apparently some others were under the assumption
that RuntimeInit.commonInit() runs before the Zygote fork. Actually, it
does not.
This CL introduces a method ZygoteInit.preForkInit() which runs before
the Zygote fork. For now, only enableDdms() moves into it and can become
private. This should not alter behavior since enableDdms() is called
from the same places as before, and because enableDdms() (now private)
was already not part of any API surface.
The CL also removes the qualifier "final" from the (static) method
enableDdms(), because it is redundant.
Note: This CL was uploaded with --no-verify because of preexisting
import ordering issues in RuntimeInit.java
