Updates also include:
- Add APIs to query current Simulcrypt channel & stream status;
- EMM format change (used only to carry fingerprinting and service
blocking info);
- Key fetcher example to use curl key fetcher.
Widevine ECM v3 is redesigned mainly based on protobuf, and supports new features including carrying fingerprinting and service blocking information. Existing clients must upgrade the Widevine CAS plugin to use the new ECM v3.
2) Add a binary wv_cas_types_example.
3) Surface wv_cas_key_fetcher *source code* to partner to serve as an example of how they would make a HTTP request to acquire an entitlement key from license server.

-------------
Add libcurl to media_cas_packager_sdk. libcurl will later be used by a key fetcher to retrieve entitlement key from License Server using a HTTP request.
-------------
Add a function named parsehelper to parse DCSL from the key smith response.
-------------
Move wv_cas_key_fetcher to media_cas_packager_sdk so partners can use it request entitlement keys from License Server.
-------------
Add pkcs7 write method to x509_cert.cc
-------------
Update boringssl_repo to latest in master-with-bazel
-------------
Add a TsPacket class to media_cas_packager_sdk to allow the construction of a ECM TS packet in the SDK.
-------------
Move InsertEcm() from our internal CAS directory to the media_cas_packager_sdk, to be used to build a ECM TS packet by the SDK.
-------------
Add METADATA in common folder
-------------
Refactoring of certificate verification into DrmRootCertificate.
-------------
Extend the default duration of leaf certificates.
-------------
Fix moe_test
-------------
Add a new method to WvCasEcm to allow partner to create a TS packet carrying the generated ECM.
-------------
Change from SHA1 to SHA256 for Cast certificates
-------------
Update crypto mode enumeration to match WV ECM document
-------------
Fix the way we set the validity dates
-------------
Move exported_root/util/status to common/ to prepare for util::Status migration
Also added constructor/operator to copy from/to util::Status.
-------------
Add GenerateDCSLrequest function to certificate_util.h.
-------------
Fix build break
-------------
Allow 'table_id' (in the section header) be specified by caller of SDK method WvCasEcm::GenerateTsPacket().

Pad key value when crypto_mode is DVB_CSA, so that the key length is always 16 bytes.
-------------
Minor comment and example code update.

(2) Add a new enum value for kDvbCsa.
(3) Allow caller to specify CTR, CBC, as well as CSA when using the ecm genertor from the SDK.

-------------
Moves ecm_generator to media_cas_packager_sdk/internal.
-------------
Add a simple TCP server listening on a port. My intention is to use this server to support the Simulcrypt APIs (TODO).
Also add a simple TCP client binary for testing the server and also demo how to call the Simulcrypt APIs (TODO).
-------------
If only a single key is in the ECM, it is the EVEN key. To make the code matches this understanding, change a parameter from 'false' to 'true'. But this change has NO impact on the produced ECM, regardless this parameter is 'false' or 'true' (i.e., whether using push_front or push_back), only a single key is in the ECM.
-------------
Add classes that process Simulcrypt ECMG messages
1) Stream_set-up
2) CW_provision
-------------
Renames server and client binaries.
-------------
Make ecmg call ecm_generator to generate ecm. The return of the ecm to Simulcrypt caller will be implemented in the next CL.
For now, using the 'key' (control word) in CW_provision message also as the 'key_id'.
-------------
Move common folder
