Exports get_bc_pad() to be used from tests. Adds separate handcrafted
tests for block cipher padding modes. They were previously only tested
implicitly during the block cipher modes of operation tests, though not
all padding modes were covered. And in case a mode of operation is
not part of the enabled modules, the previously tested padding modes
are not covered at all. Fixes an off-by-one bug in the previously
untested ANSI X9.23 padding mode, where the number of zero bytes
in the pad was one more than allowed by the standard.

In some cases this can offer better optimization, via devirtualization.
And it lets the user know the class is not intended for derivation.

Transforms and BlockCiphers. Registration for all types is done at
startup but is very cheap as just a std::function and a std::map entry
are created, no actual objects are created until needed. This is a
huge improvement over Algorithm_Factory which used T::clone() as the
function and thus kept a prototype object of each type in memory.
Replace existing lookup mechanisms for ciphers, AEADs, and compression
to use the transform lookup. The existing Engine framework remains in
place for BlockCipher, but the engines now just call to the registry
instead of having hardcoded lookups.
s/Transformation/Transform/ with typedefs for compatability.
Remove lib/selftest code (for runtime selftesting): not the right approach.

Update license header line to specify the terms and refer to the file,
neither of which it included before.
