print-jobs which have last-modification times that are in the future.
This shouldn't happen, of course, but it can. And when it did happen,
the previous check could cause completely-spooled jobs to sit in the
queue for 20 minutes per job. The new code waits until the last-modify
time is not changing, instead of making decisions based on the specific
value of last-modify.

Std 1003.1-2008. Both Linux and Solaris conforms to the new definitions,
so we better follow too (older glibc used old BSDish alphasort prototype
and corresponding type of the comparision function for scandir). While
there, change the definitions of the functions to ANSI C and fix several
style issues nearby.
Remove requirement for "sys/types.h" include for functions from manpage.
POSIX also requires that alphasort(3) sorts as if strcoll(3) was used,
but leave the strcmp(3) call in the function for now.
Adapt in-tree callers of scandir(3) to new declaration. The fact that
select_sections() from catman(1) could modify supplied struct dirent is
a bug.

about a queue from a remote host. That remote host may use \r, \r\n,
or \n\r as the line-ending character. In some cases the remote host
will write a single line of information without *any* EOL sequence.
Translate all the non-unix EOL's to the standard newline, and make
sure the final line includes a terminating newline. Logic is also
added to translate all unprintable characters to '?', but that is
#if-ed out for now.

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.

Due to this bug, the first job ever sent to a queue could leave

for calculating the job number for a job based on the control-file name.
We might receive cf-files named by other implementations of lpr, where
the job number shown by lpq would not match the job number that other
commands expected for the same name.
This also uses a newer algorithm for determining a job number, to avoid
problems caused when a control-file is named using an IP address, instead
of the hostname.
This also moved the declaration if isowner() from lp.h to rmjob.c. When I
went to change the parameters, I noticed that rmjob.c was the only source
file which uses it.

control-file for each print job. This is partially because the previous
checks still let through some characters which would cause trouble for
other applications which try to process the resulting userid -- such as
accounting programs.
But the main reason is to handle the case where some remote host sends a
print job where the given userid is an uppercase-version of the real userid.
For that case, lpd will now check for uppercase letters in the userid. If
there are any, it will check to see if the given userid (with the uppercase
letters) is a valid one. If it is *not* valid, then lpd will change the
userid to all-lowercase right when the job is received.

sure the data file has been completely transfered before starting to
print it. This is needed because some implementations of lpr will send
the control-file for a print job before sending the matching data-files,
and that can cause problems if the receiving host is a busy print-server.
