Add a new getty/gettytab capability to generate an initial message dynamically.

This modification adds a new gettytab(5) option (iM) to specify a
program to run that will generate the initial (banner) message that is
displayed before the login prompt. Such a capability is useful when
dynamic information is needed in the banner message that cannot be
supplied by the set of % substitution sequences available in the "im"
option.

Try to fix the old "he capability is stupid" bug in gettytab(5)/getty(8)

There is one capability explicitly documented in gettytab(5) as stupid: he.
And it is indeed. It was meant to facilitate system hostname modification,
but is hardly usable in practice because it allows very limited editing
(e.g., it depends on a particular hostname length, making it non-generic).

Replace it with simple implementation that treats ``he'' as POSIX extended
regular expression which is matched against the hostname. If there are no
parenthesized subexpressions in the pattern, entire matched string is used
as the final hostname. Otherwise, use the first matched subexpression.
If the pattern does not match, the original hostname is not modified.

Using regex(3) gives more freedom, does not complicate the code very much,
and makes a lot more sense, in turn making ``he'' less stupid and actually
useful (e.g., it is now possible to obtain node or domain names from the
original hostname string, without knowing it in advance).

A PPP login program is started _automatically_ (i.e., without
human intervention) even with the "pl" capability unset, as soon
as a PPP frame is detected. But with "pl" set, a PPP login program
is started independently of the result of PPP detection (which is
rendered unnecessary then,) i.e. _unconditionally_.
