composer@2.x-hal is a header library. Any of the shared
libraries it depends on must also be included by anyone
who includes composer@2.x-hal. This means when we add a new
version of mapper, anyone who uses composer@2.x-hal must
also include the new version of the mapper. Vendors
that depend on composer@2.x-hal are broken every time we
add a new mapper.
This patch refactors ComposerResources into a seperate
shared library. ComposerResources contains all of the
mapper code. composer@2.x-hal will depend on the new
composer@2.x-resource hal. Everyone downstream must
also add the composer@2.x-resource file now. However,
they will not be broken again when we add a new mapper
version.

Add ComposerResources to the HAL support library to replace
HandleImporter, DisplayData, and BufferCache in ComposerClient.
ComposerResources tracks the current displays and layers, as well as
managing buffer caches for them.
This is more than refactoring. HandleImporter used to be a static
object, but we want ComposerResources to be self-contained rather
than depending on a static object. This needs to be fixed. It also
becomes obvious that we used to treat sideband streams as buffers in
BufferCacheEntry destructor incorrectly. That needs to be fixed as
well (as a trivial consequence of making HandleImporter non-static).

Create android.hardware.graphics.composer@2.1-hal and add
ComposerHal, which is heavily based on ComposerBase, to it.
There are two bigger TODOs. One is to remove the concept of
"clients" from the class and the other is to remove hwcomposer2.h
dependency.
