121d554c20 Change order of loading certificates from pk7 cert
-------------
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().

9962e87676 Specify widevine/media_cas_packager_sdk/presubmit in media_cas_packager_sdk METADATA file.
-------------
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
