The previous defaulting to TERMIOS took away -DTERMIOS / -DTERMIO a
bit too enthusiastically.  Windows/DOSish platforms of all sorts get
identified as OPENSSL_SYS_MSDOS, and they get a different treatment
altogether UNLESS -DTERMIO or -DTERMIOS is explicitely given with the
configuration.  The answer is to restore those macro definitions for
the affected configuration targets.

The rationale for this move is that TERMIOS is default, supported by
POSIX-1.2001, and most definitely on Linux.  For a few other systems,
TERMIO may still be the termnial interface of preference, so we keep
-DTERMIO on those in Configure.

crypto/ui/ui_openssl.c is simplified in this regard, and will define
TERMIOS for all systems except a select few exceptions.

Specifically, an ASN.1 NumericString in the certificate CN will fail UTF-8 conversion
and result in a negative return value, which the "x509 -checkhost" command-line option
incorrectly interpreted as success.

Also update X509_check_host docs to reflect reality.

Thanks to Sean Burford (Google) for reporting this issue.
