There is a potential integer overflow to bypass the
source base size check in decrypt. The source pointer
can then point to the outside of the source buffer,
which could potentially leak arbitrary memory content
to destination pointer.

CdmResponseType are mapped to android::status_t, then map to hidl
android::hardware::drm::V1_0::Status. This CL removes the indirection
by mapping cdm errors to hidl Status.

Earlier versions of android returned CryptoException with
error code ERROR_NO_KEY, when a decrypt call was received before keys were
loaded. Changes to O resulted in ERROR_SESSION_NOT_OPENED being returned
instead. This CL reverts the behaviour.
Also a change to correct CDM error code numbering in comments.
Test: Verified by unit and integration tests

The security level (software/hardware, decryption/decode)
in the policy that specified how the key was to be used was
not being respected for L3. Playback would either continue or
a vendor specific error would be thrown.
If the device cannot use the key as permitted by the policy
CryptoException#ERROR_INSUFFICIENT_OUTPUT_PROTECTION will be thrown.
Test: Verified by WV unit+integration tests.

hidl_string no longer will provide an implicit cast to const char* as it
interfers with other expected behaviors of the class. It now emulated
std::string in requiring a call to .c_str() to get the same behavior.

This cleans up some warnings in the Android glue code:
1) Checking if unsigned values are >= 0.
2) Using {0} initializer syntax instead of fully expanding to {0,0}.
