Some HALs, like a.h.graphics.mapper, are always passthrough and are
used by nearly all app processes. Preload those in Zygote to save app
startup time and share more pages between processes. This has the side
effect of also preloading a bunch of HIDL-related system and vndk
libraries that would also otherwise be loaded independently by every
app.
An earlier attempt at this change tried to preload the HAL via a
static initializer in libui.so (which is already preloaded, and which
is the immediate client of the HAL). But several other non-Zygote
processes also use libui.so, and didn't have SELinux permission to
access the device nodes used by the HAL. This version uses an explicit
call from Zygote to preload the HAL, instead of doing it implicitly.

Test: check that a.h.graphics.mapper is in /proc/`pid zygote64`/maps

Add an attribute android:classLoader which can be set to the name
of the classloader the base or split wishes to use. For now, this can
only be set to "dalvik.system.PathClassLoader" or
"dalvik.system.DelegateLastClassLoader". The current implementation
only allows the classloader to exist in the boot classpath but that
restriction can be loosened in a future change if necessary.

SharedMemory is parcelable and AIDL friendly
and exposes cool things like dropping write permissions
that are useful for shared memory to have.
Also exposes getFileDescriptor() on MemoryFile
since that was necessary to use MemoryFile
with IPC previously and there are a sizeable
number of reflections that access it, so just make
it public.
Test: SharedMemory CTS tests pass

The property is dalvik.vm.hot-startup-method-samples, setting this

marked as hot in the profile.

We introduce a new property dalvik.vm.stack-trace-dir that indicates
that we're using one trace file per dump. The runtime does not need
to know what the directory is, since it will communicate with
tombstoned in order to obtain a file descriptor to which it will write
its traces. In this change, we set the -Xtombstonedtraces flag whenever
dalvik.vm.stack-trace-dir is set.

The GraphicsEnvironment class is given information during application
start, and makes it available to EGL/GLES/Vulkan loaders that don't
have easy access to the VM or to the application Context. Currently
only the driver path is handled, but the existing support for setting
library paths (for Vulkan extensions) and cache directory information
should move here.
