Since KDF functions are only used right before specific functions, this
merges them to simplify internal state within OEMCrypto.

With ECC based DRM cert, the session key is expected to be 32, as
compared to 16 bytes in RSA case. This CL adds supports for 32 bytes
session key.

(This is a merge of http://go/wvgerrit/140850.)
This patch fixes a number of minor issues in the codebase (mostly
instances of 0-as-nullptr, but also some member shadowing and a missing
override) that were being hidden by the fact that depending on Protobuf
disables these diagnostics. And which will be unhidden when a later
patch removes that behavior from Protobuf.

(This is a merge from the Widevine Repo of http://go/wvgerrit/134310.)
This patch fixes code that would trigger -Wshorten-64-to-32 by
implicitly narrowing a variable from 64 to 32 bits. Most of the time, it
does this by making the implicit conversion explicit. The cause of most
of these is that OpenSSL uses "int" for the length of things rather than
size_t. (While BoringSSL sometimes uses int and sometimes uses size_t.)
One exception is LogBoringSSLError(). We have a couple copies of this
function around, and they varied slightly. This patch brings them all
in-line, which conveniently also removes any code in them that would
deal with integer variables.
GetRandBytes() now takes a size_t and downcasts to BoringSSL's native
int internally, so that callers can pass in a size_t value as they would
expect.
There's also an interesting case in oec_session_util.cpp. Because
BoringSSL and OpenSSL disagree about the width of an error code, we have
to use the "auto" type for a temporary variable that holds an error, in
order to retain compatibility with both.

This is a cherry pick of recent changes to OEMCrypto and ODK. Most of
these are part of the document migration to doxygen.
