void blkfree(char **);

various fixes suggested by Robert Elz:
* implement closedataconn() and use appropriately (including in mlsd())
* only put leading space in front of MLST output (not MLSD output)
* MLSD: only output pdir and cdir entries when the type fact is requested.
* change error code for giving MLSD a non-directory from 550 to 501
* remove MLSx Type fact support for UNIX.* for now; it's not standardised yet.
* do a check_login when MLSD and MLST are given no args
* detect & complain about null facts in OPTS MLST
* cache getgroups() at login instead of calling each time in fact_perm()
other mods:
* implement cprintf(); as per fprintf() but increments total_bytes{,_out}
* implement CPUTC(); as per putc() but increments total_bytes{,_out}
* implement base64_encode()
* fact_unique() display base64 encoding of dev_t and ino_t rather than
hex output; should scale if size of those changes
* change reply() so that a negative code acts as the initial line in a reply,
code == 0 prefixes the line with 4 spaces, and code > 0 works as before.
deprecate lreply(code, ) and lreply(0, ) in favour of reply(-code, ) and
reply(0, ) respectively.
* use cprintf() and CPUTC() appropriately (often instead of printf(),
lreply(-2, ) or lreply(-1, ).
now we actually account for the data sent by MLST and MLSD.
* remove DEBUG support for sending MLSD output to control connection instead
of data connection (my ftp client now supports MLSD :-)

hostglob (e.g, `*.foo.com'), and the remote host is matched against that.
- if classname is given, use that to match entries in ftpd.conf (defaults
to `guest' for `anonymous'/`ftp' logins, `chroot' for users found in
/etc/ftpchroot, and `real' for everyone else.
* implement new /etc/ftpd.conf directives:

motd classname file file to use instead of /etc/motd
rateget classname rate set rateget throttle to rate
rateput classname rate set rateput throttle to rate
upload classname allow/deny uploads (STOU, STOR, APPE). if
denied, also acts as `modify deny'.
* implement new `SITE' commands:
RATEGET as per /etc/ftpd.conf rateget, but cannot exceed that
RATEPUT as per /etc/ftpd.conf rateput, but cannot exceed that
* implement format_file(), which outputs a file to the user, parsing %
escapes. use to print /etc/ftpwelcome, /etc/motd, and the `display' file.

optional suffix (for use with rateget, etc)

various fixes suggested by Robert Elz:
* implement closedataconn() and use appropriately (including in mlsd())
* only put leading space in front of MLST output (not MLSD output)
* MLSD: only output pdir and cdir entries when the type fact is requested.
* change error code for giving MLSD a non-directory from 550 to 501
* remove MLSx Type fact support for UNIX.* for now; it's not standardised yet.
* do a check_login when MLSD and MLST are given no args
* detect & complain about null facts in OPTS MLST
* cache getgroups() at login instead of calling each time in fact_perm()
other mods:
* implement cprintf(); as per fprintf() but increments total_bytes{,_out}
* implement CPUTC(); as per putc() but increments total_bytes{,_out}
* implement base64_encode()
* fact_unique() display base64 encoding of dev_t and ino_t rather than
hex output; should scale if size of those changes
* change reply() so that a negative code acts as the initial line in a reply,
code == 0 prefixes the line with 4 spaces, and code > 0 works as before.
deprecate lreply(code, ) and lreply(0, ) in favour of reply(-code, ) and
reply(0, ) respectively.
* use cprintf() and CPUTC() appropriately (often instead of printf(),
lreply(-2, ) or lreply(-1, ).
now we actually account for the data sent by MLST and MLSD.
* remove DEBUG support for sending MLSD output to control connection instead
of data connection (my ftp client now supports MLSD :-)

* make checkportcmd the default. this breaks third-party proxy ftp but
prevents the ftp bounce attack, and we should be secure out of the
box, not require users to tweak obscure stuff.
* allow the version string reported to clients to be changed with '-V vers'.
if vers is empty or `-', don't report a version.
* if -r is given, permanently drop root privs
* if not a REAL user (i.e, GUEST or CHROOT), and ftpd is running on a port
> IPPORT_RESERVED+1, permanently drop root privs
* don't bother reverting to root privs to logout of wtmp/utmp; since the
file descriptor is already open this isn't necessary.
* fix the binding of the port for the PORT/LPRT/EPRT connection to be the
ctrl_addr.su_port-1, not hardcoded to `20' (this was broken in the ipv6
merge). if root privs have been dropped, and this would be a port <
IPPORT_RESERVED, use a random port instead (which isn't RFC959 compliant
but it doesn't appear that many clients care).
* prevent login of a new user if privs have been dropped and already logged
in as a REAL user (existing check already stops GUEST & CHROOT users).
* move the port check stuff into a separate port_check() function, and use
for PORT, LPRT, and EPRT checks. inspired by freebsd
* minor KNF
* minor man page cleanup

* change format of /etc/ftpusers lines from
userglob [allow|deny]
to
userglob[@host] [allow|deny [classname]]
where class is a userdefined classname.
- if host is given it may either be a CIDR address (e.g, `1.2.3.0/24') or a
hostglob (e.g, `*.foo.com'), and the remote host is matched against that.
- if classname is given, use that to match entries in ftpd.conf (defaults
to `guest' for `anonymous'/`ftp' logins, `chroot' for users found in
/etc/ftpchroot, and `real' for everyone else.
* implement new /etc/ftpd.conf directives:
classtype classname type set type of classname to GUEST, CHROOT, or REAL
motd classname file file to use instead of /etc/motd
rateget classname rate set rateget throttle to rate
rateput classname rate set rateput throttle to rate
upload classname allow/deny uploads (STOU, STOR, APPE). if
denied, also acts as `modify deny'.
* implement new `SITE' commands:
RATEGET as per /etc/ftpd.conf rateget, but cannot exceed that
RATEPUT as per /etc/ftpd.conf rateput, but cannot exceed that
* implement format_file(), which outputs a file to the user, parsing %
escapes. use to print /etc/ftpwelcome, /etc/motd, and the `display' file.
* implement strsuftoi() (from ftp(1)), which parses a number and
optional suffix (for use with rateget, etc)
* don't bother seteuid(0) ; bind(...) ; seteuid(pw->pw_uid), since
we don't need reserved ports (at wasn't getting them anyway).
* update & reorder copyrights
* use strlcpy() as appropriate
