    Most common browsers are lax in thier handling of how the
    emailAddress field is encoded. RFC 3280 section 4.1.2.6
    defines the encoding as IA5String, however browsers will
    also handle certificates with the emailAddress field
    encoded as UTF8String. This fix allows the emailAddress
    to be decoded as both an IA5String and an UTF8String.

Sometimes the size of a response could be as a string.
[inets/httpd] Improved request handler terminate error-log entry

If a request handler terminates abnormally (terminate reason not
normal), the error-log entry was a bit obtuse ("Internal Server Error").
This has been improved so that the log entry now also include the
actual terminate reason.

This is step one in in making ssh process structure less complicated.
As an effect I also found other simplifications/clean ups of the code
that could be done.
