Manifest Tool v2.0.0

Works with client-lite.

Key differences from previous version:

	Manifest 1.5.2	Manifest 2.0.0
Supported manifest schema version	v1	v1 and v3
Delta update	Supported	Supported
Component update	Not supported	Supported
PDMC	Supported 4.5.0 or earlier	v1 support covers PDMC, v3 support is only available on Client Lite
Client Lite	Supported	Supports both v1 (by default) and v3 and can be configured at build time

Changes:

• introduce new ASN manifest format v3
• added delta-tool as Python module
• introduced Semantic version format
• add an option to sign candidate image using update private key -
  allowing to implement secure boot on a device side
• work with ECDSA raw signatures (R||S) - reduce verify code size on
  target device
• simplified command line interface
  • split between developer and production tools:
    • manifest-tool - is for production use
    • manifest-dev-tool - is for developer use only
    • manifest-delta-tool - is the tool for preparing delta patches
• cleanup developer tool CLI by removing various configuration that
  have no practical use at current point
• backward comparability with ASN manifest format v1 is preserved via
  dedicated commands:
  • manifest-tool create-v1
  • manifest-dev-tool update-v1
  • manifest-dev-tool create-v1
