Initial support for split APKs, PackageInstaller. 

Defines a new PackageInstaller class that will be used for installing
and upgrading packages.  An application desiring to install an
application creates a session, stages one or more package files in
that session, and then kicks off the install.

Previously, PackageManager would always make its own copy of a package
before inspecting it, to ensure the data could be trusted.  This new
session concept allows the installer to write package data directly to
its final resting place on disk, reducing disk I/O and footprint
requirements.  Writes are directed through an intermediate pipe
to ensure we can prevent mutations once an install has been initiated.
Also uses fallocate() internally to support optimal ext4 block
allocation using extents to reduce fragmentation.

Sessions are also the way we support installing multiple "split" APKs
in a single atomic operation.  For a set of packages to form a valid
application, they must have exactly the same package name, version
code, and certificates.  A session can also be used to add a small
handful of splits to an application by inheriting existing packages
when not performing a full install.

Add PackageParser support for extracting split names and certificates.
