Move to using std::vector and std::unique_ptr to manage key
certificates to stop memory leaks.

Changes minzip and recovery's file signature verification to work on
memory regions, rather than files.
For packages which are regular files, install.cpp now mmap()s them
into memory and then passes the mapped memory to the verifier and to
the minzip library.
Support for files which are raw block maps (which will be used when we
have packages written to encrypted data partitions) is present but
largely untested so far.

This adds support for key version 5 which is an EC key using the NIST
P-256 curve parameters. OTAs may be signed with these keys using the
ECDSA signature algorithm with SHA-256.
