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.

Client ID name-value fields in the license request share the same
namespace with app parameters and WV standard device information. As
a result, it was possible for applications to provide parameters that
could potentially fool the license server with spoof values.
This CL restricts the use of the fields that are common across both the
Android CDM and CE CDM. Currently, Android specific fields are
restricted by the MediaDrmPlugin layer, and there are no CE CDM
specific fields currently defined.
The non-HIDL DRM plugin does not restrict these fields; however, it
will be removed in S.

Qualcomm SoC may report 10085 (RSASSA-PSS signature error) when
OEMCrypto_PrepareAndSignLicenseRequest is called. The app needs to
reprovision (or the user needs to factory reset their device) in order
to recover.
If the 10085 error is returned, the app currently will get a
MediaDrmStateException. The app has no way to be able to tell
whether this is due to the 10085 error or some other error.
This change returns a NEED_PROVISIONING error at the CDM level, which
will result in the app receiving a NotProvisionedException when
MediaDrm.getKeyRequest is called.

The conditional compilation for flagging the CDM and ODKiTEE logging
functions as printf-like was guarded by a check on "__gnuc__" or
"__clang__". However, GCC doesn't actually define "__gnuc__", it
defines "__GNUC__", all caps. Fixing this causes GCC to find a slew
of format-string errors that Clang was accepting. This patch fixes the
capitalization and the uncovered errors, most of which fall into one of
a few categories:
1) The format string and variable had different signedness. For these,
the format strings are updated to match the variables.
2) The variable was an array index that was not of size_t. For these,
the variables have been updated to be size_t and the format strings
have been updated to use %zu. A few index variables that weren't
actually used in format strings are also fixed to be size_t.
3) The code assumed the signedness of the internal representation of an
integer literal, enum constant, or enum variable. For these, I either
cast the input to a known type so that the format string is valid
regardless of internal representation or I switched to a hexadecimal
format string. The latter case is more useful on ODKiTEE enums where
the literal value is in the code as a 32-bit hexadecimal value
anyway.
This patch also adds missing integer casts to the enum literals in the
ODKiTEE logging header. (These are required for pedantic C99
compatibility when using literal values that do not fit into a 16-bit
integer.)

Also added ODK dependency which is required by L3 v16.
Do not replace constant sizeof() with a hard-coded value in L3 library because it is target-specific.

The CDM property string and MediaDrm property string for the usage
table capacity did not follow the same pattern used for matching all
other property strings. This changes the CDM's version of the string
to match the MediaDRM version. The property string mapper will
automatically be updated when the CDM is updated on Android.
The change in property string was tested on Android R using the
license request integration test.

Previously, we worked around a problem by signing a fake license
request when a license did not have a usage entry. However, this was
inside a conditional that the device did support usage tables. This CL
moves that code outside the conditional so that a fake license is
signed whenever the license does not have an entry.

When running the local license server, the license does not contain a
URL for the renewal, or it is mangled. We only need to run this test
if we are running against UAT or UAT Nightly.
