src/usr.bin/id, branch release/9.2.0

Add two new system calls, setloginclass(2) and getloginclass(2). This makes

2011-03-05T12:40:35+00:00

it possible for the kernel to track login class the process is assigned to,
which is required for RCTL.  This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).

In preparation for raising NGROUPS and NGROUPS_MAX, change base

system callers of getgroups(), getgrouplist(), and setgroups() to
allocate buffers dynamically.  Specifically, allocate a buffer of size
sysconf(_SC_NGROUPS_MAX)+1 (+2 in a few cases to allow for overflow).

This (or similar gymnastics) is required for the code to actually follow
the POSIX.1-2008 specification where {NGROUPS_MAX} may differ at runtime
and where getgroups may return {NGROUPS_MAX}+1 results on systems like
FreeBSD which include the primary group.

In id(1), don't pointlessly add the primary group to the list of all
groups, it is always the first result from getgroups().  In principle
the old code was more portable, but this was only done in one of the two
places where getgroups() was called to the overall effect was pointless.

Document the actual POSIX requirements in the getgroups(2) and
setgroups(2) manpages.  We do not yet support a dynamic NGROUPS, but we
may in the future.

them (for example when they have logged in from an ip6 source).

- Stick with the initial call to getaudit(2), if it returns E2BIG, use
  getaudit_addr(2) instead and set the "extended" flag to indicate that
  we the calling credential has an extended subject state.
- Additionally, add the printing of the machine/at_addr (the ip/ip6
  addresses)
