memory allocation failures.

env.c [revs 1.8, 1.9] Fix a situation where a pointer which should
point to dynamically allocated memory was instead pointed to a static

Use getpwnam before getpwuid since two users with same uids can exists
(affects new login classes code only)

The same fixes as in inetd: by default run `system crontab things' with
daemon login class now, not restrict them to user class breaking
compatibility with old way (so-called nobody limits problem)

Implement user[:group][/login-class] syntax in system crontab
for more flexible control (the same as in inetd)

NOPIC is used to not generate a shared library, not NOSHARED.
Make NOSHARED advisory where appropriate.
Remove bogus NOSHARED (kbdio).

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

used by OpenBSD.  (Quite frankly, I think it's perfectly reasonable to
use snprintf to copy strings, given that the semantics for strncpy()
are utterly idiotic and there is no POSIX sstrncpy().)

While I'm at it, incorporate some of OpenBSD's bugfixes to cron.

NOT for 2.2
