Fix error message to be accurate for when ProgName is not "sysinstall" (oops?)

Better to just statically set the name vs. determine at run time.

setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

Back out all POSIXified *env() changes.

Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

Prepare for upcoming POSIXed putenv() rewrite:

don't allow putenv() arg be on the stack, use strdup()

Fixed assorted misuses of NULL in integer context.

This option adds Postfix and Exim to the list, however, qmail is not added

Add a couple of functions to create persistent variables that will

2001-09-24T10:16:23+00:00

survive a sysinstall Ctrl-C -> 'Restart'.  This fixes another annoying
bug where restarting sysinstall will try to reload kernel modules and
do other external things that have already been done.  For now, use
these persistent variables to keep track of module, usbd, and pccardd
initialization.
