This changes the internals of vboot2 to use the enumerated type for
signature algorithm. The conversion from crypto algorithm is done
only when unpacking the key. This is preparation for the vboot2 data
types, which separate signature and hash algorithms into their own
fields.
There is no external change in the calling API to vboot, and no change
to the external data structures.

goes away in the next change). This is preparation for the vboot2

This removes code duplicated between 2common.c and 2rsa.c. This is in
preparation for adding new unsigned hash algorithms.

This allows the algorithm list to be shared by code which simply needs
to look at the vboot structures.
No functional changes; just moving enums around and adding comments.

This is the first of several CLs adding a more memory- and
code-efficient firmware verification library. This CL adds the crypto
library (modified from firmware/lib/cryptolib) and unit tests for it.
