/**
* Keep track of all those APKs everywhere.
* <p>
* Internally there are two important locks:
* <ul>
* <li>{@link #mPackages} is used to guard all in-memory parsed package details
* and other related state. It is a fine-grained lock that should only be held
* momentarily, as it's one of the most contended locks in the system.
* <li>{@link #mInstallLock} is used to guard all {@code installd} access, whose
* operations typically involve heavy lifting of application data on disk. Since
* {@code installd} is single-threaded, and it's operations can often be slow,
* this lock should never be acquired while already holding {@link #mPackages}.
* Conversely, it's safe to acquire {@link #mPackages} momentarily while already
* holding {@link #mInstallLock}.
* </ul>
* Many internal methods rely on the caller to hold the appropriate locks, and
* this contract is expressed through method name suffixes:
* <ul>
* <li>fooLI(): the caller must hold {@link #mInstallLock}
* <li>fooLIF(): the caller must hold {@link #mInstallLock} and the package
* being modified must be frozen
* <li>fooLPr(): the caller must hold {@link #mPackages} for reading
* <li>fooLPw(): the caller must hold {@link #mPackages} for writing
* </ul>
* <p>
* Because this class is very central to the platform's security; please run all
* CTS and unit tests whenever making modifications:
*
* <pre>
* $ runtest -c android.content.pm.PackageManagerTests frameworks-core
* $ cts-tradefed run commandAndExit cts -m CtsAppSecurityHostTestCases
* </pre>
