caused a segfault. It turns out that in pre-7.0 systems if you do
getenv("amd_enable=YES") it will return the setting of the environment
variable "amd_enable" but now it returns NULL. I think I found the
places where sysinstall was potentially relying on that old behavior.
Fix is to make a copy of the string to be used for the getenv(3) call,
look for a '=' character in it, and replace it with '\0' if one is
found. Stuck to sysinstall's typical coding standards despite urges
to do otherwise.

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.

id used by sysinstall when enabling anonymous FTP.
Change the default group used by sysinstall for setting up anonymous FTP
from operator to ftp; there is no reason to use operator and there are
potential security issues when doing so.

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.
complete the boot and enter into sysinstall, and only then inserts
a CD into the CDROM drive and tries to select that as the install
media the first call to mount(2) generates EIO but the second call
to mount(2) will succeed. This was 100% reproducible on 6.2-RELEASE,
RELENG_6, and HEAD. If the user inserts the disc into the CDROM
while the machine is booting off the floppies the first call to mount(2)
succeeds with no problems. The problem was originally reported in
PR #56952 against 5.1-CURRENT so it's been there for a while now.
