Allow equality checking and hash for HIDL interface proxies.

IFoo.Proxy.equals() -> HidlSupport.equals() ->
IHwInterface.asBinder().equals() -> HwRemoteBinder.equals().
IFoo.Stub.equals() -> default Object.equals()

Notice that IHwInterface.asBinder() returns mRemote(of type
HwRemoteBinder) for proxies and itself (of type HwBinder) for stubs.
If IFoo.Stub.asBinder() had not return "this", its equals()
should also be overridden.

hidl-gen user guide

1. Build

croot
make hidl-gen

2. Run

hidl-gen -o output-path -L language (-r interface-root) fqname

output-path: directory to store the output files.
language: output file for given language. e.g.c++, vts..

fqname: fully qualified name of the input files.
For singe file input, follow the format: package@version::fileName
For directory input, follow the format: package@version

interface-root(optional): prefix and root path for fqname.
If not set, use the default prefix: android.hardware and default root path
defined in $TOP.

examples:

croot
hidl-gen -o output -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0::INfc.hal
hidl-gen -o output -L vts -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
hidl-gen -o test -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
hidl-gen -L hash -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
