media_cas_packager_sdk_source/common/drm_root_certificate.cc
Fang Yu 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().

-------------
