Deprecate the "hw" configuration options, make "padlockeng" disablable
The "hw" and "hw-.*" style options are historical artifacts, sprung
from the time when ENGINE was first designed, with hardware crypto
accelerators and HSMs in mind.
Today, these options have largely lost their value, replaced by
options such as "no-{foo}eng" and "no-engine".
This completes the transition by making "hw" and "hw-.*" deprecated,
but automatically translated into more modern variants of the same.
In the process, we get rid of the last regular expression in
Configure's @disablables, a feature that was ill supported anyway.
Also, padlock now gets treated just as every other engine.
