The peril of not using calloc mean delete_all is not initialized until
we explcitly set it. Explicitly set delete_all to NULL to avoid that.

ENGINE_by_id will load up multiple copies of the engine which will
create a new ex_data index each time it's called. This change makes sure
the ex_data index is only initialized once.

This is so that Face Unlock can be a valid option for a lockscreen.
Otherwise get a PERMISSION_DENIED when uid = 101000.

Turn on the compiler flags -Wall -Wextra -Werror to make sure no
compiler warnings are added to the project.

Eliminate all unused arguments. Remove unused variables in code.

Use the UniquePtr.h include from frameworks/native/include/utils
to fix the pdk build.

Old key types were not distinguished by the keystore itself. This change
takes some of the reserved fields in the old format and changes it to a
version number and key type.

To allow efficient deletion by hardware keymaster modules, add a direct
delete_all call when keystore is reset. This will also probably fix
problems where the hardware keymaster gets more keys than keystore knows
about and fills up its storage.

Add hardware crypto capabilities to keystore. This allows hardware
escrow of private key material.

There is also an OpenSSL engine that connects to keystore to allow use
of the keystore keys from native code built into the platform.

This includes a software implementation of keymaster using OpenSSL
as the backend.  This is just as insecure as the previous solution,
but it's needed so devices without hardware support can continue
to operate in the new scheme without a lot of compatibility code.

Add a libkeystore_client.so library for clients to use.

Add const-correctness to the keystore.cpp classes.

Increase maximum arguments for future work.
