getlogin_r is specified by POSIX to to take a size_t len, not int. Fix our
version to do the same, bump the symbol version due to ABI change and
provide compat.
This was reported to break compilation of Ruby 2.8.
Some discussion about the necessity of the ABI compat did take place in the
review. While many 64-bit platforms would likely be passing it in a 64-bit
register and zero-extended and thus, not notice ABI breakage, some do
sign-extend (e.g. mips).

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Stop calling system calls "function calls".
Use "The .Fn system call" a-la "The .Nm utility".
When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.
interface was based on a draft version of POSIX whereas the final
(1996) version of POSIX specified that the error is returned.
While I'm here, fix getlogin_r so that it works for more than just
the first time it's called.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$

the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

explicit that it is global to the entire "session", and that setsid() or
daemon() are need to have been called at some point.
The most notable offender of setlogin() misuse is XFree86's xdm.
