buffet: Added advanced error reporting

Created chromeos::Error class that encapsulates rich error
information from various system domains.

Swept GCD device registration, HTTP transport and utilities
to always return additional error information when the caller
requests it. This includes internal errors, general HTTP errors
as well as parsing and returning specific GCD and OAuth2 server
error responses.

Also fixed a number of existing linter warnings.

BUG=chromium:366709
TEST=All existing and new unit tests pass.
