return true for characters > 127.  I.e. they are allowing extended ASCII
characters through which then cause problems.  E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably.  Likewise letters with diacritical marks can also cause problems.

If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.

The implementation uses a single table with a bit for each of the defined
classes.  These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set.  They will
work for both signed and unsigned character inputs.

This allows a finer granularity when selecting which tests to run, and
makes the tests more vidible.

It tests both the use of UI_METHOD (through the apps/apps.h API) and
wrapping an older style PEM password callback in a UI_METHOD.

The best way to test the UI interface is currently by using an openssl
command that uses password_callback.  The only one that does this is
'genrsa'.
Since password_callback uses a UI method derived from UI_OpenSSL(), it
ensures that one gets tested well enough as well.
