Add warning when no authenticator, drop verify() (#5205)

Browse Source 
Print a warning when in debug mode when a BearSSL connection tries to
connect without having any defined authentication methods, since it will
fail.

Completely remove the empty axTLS compatibilty method
"::verify(char *fp, char *name)" because it can't be done w/BearSSL w/o
user code changes, and always failed.  Better to have a compile failure
when we know at compile time the app won't do what is expected.
