userspace: remove vestigial '?' cases from top-level getopt(3) loops

getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument.

userspace: remove vestigial '?' cases from top-level getopt(3) loops

getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument. We can
handle this case with the "default" failure case with no loss of
legibility. Hence, remove all the redundant "case '?':" lines.

Prompted by dlg@. With help from dlg@ and millert@.

Remove igetnext prototype for the function does not exist.

Actually, the C standard only guarantees that atexit(3) returns non-zero
on error, so tweak previous to test "atexit(...) != 0" for portability.
"OK ok ok sorry backwards" deraadt@

atexit() returns -1 on failure

remove -i from SYNOPSIS and usage();

cap_mkdb no longer needs to understand terminfo files, so remove -i.

Pretty sure this can pledge "stdio rpath wpath cpath". Commiting to start

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.

Nuke a load of trailing whitespace; no binary change.

If the last name field looks like a description rather than an alias (if it
contains spaces), ignore it. Knocks a few K off the termcap and terminfo
databases and gets rid of some warnings.

Change cap_mkdb and curses to be a better about reformatting terminfo entries
into the cap database format and back: rather than replacing all colons with
commas, only touch real separators (skip those with a leading \ or ^) and
replace an unadorned colon with a literal "\072".

Fixes problems with quite a few caps including acsc in "screen" (:s instead of
,s) and setab/initc in "xterm-256color" (wrongly concatenated together).

- move break from loop on EOF in order to make cap_mkdb not ignore the final
record in terminfo mode
- while we're here fix indentation, spelling
okay millert@

When storing termcap entry in the .db file, prune out empty entries like
:\t: since space may be tight with the 1023 character termcap limit.

Merge cap_mkdb(1) and info_mkdb(1)

getopt(3) returns -1 when out of args, not EOF, whee!
