datagram that we received, which leads to easier support for
(ignoring) the procmail messages that specify the folder to which
the message was delivered.
When reading the mailbox, if we encounter a "From " line, we should
exit(). This can occur if there are a lot of rapidly arriving, yet
short messages.
`switch()' code may be translated using a jump table approach which causes
it to reference the equivalent of a global variable, something that must
be avoided before _rtld_init() has run.
* Add ftpd.conf(5) directive `advertise'; change the address that is
advertised to the client for PASV transfers. this may be useful in
certain firewall/NAT environments.
Feature requested in [bin/9606] by Scott Presnell.
* Add -X option; syslog wu-ftpd style xferlog messages, prefixed with
`xferlog: '. An example line from syslog (wrapped):
Dec 16 18:50:24 odysseus ftpd[571]: xferlog: Sat Dec 16 18:50:24 2000
2 localhost 3747328 /pub/WLW2K601.EXE b _ o a lukem@ FTP 0 * c
These messages can be converted to a wu-ftpd style xferlog file
suitable for parsing with third-party tools with something like:
grep 'xferlog: ' /var/log/xferlog | \
sed -e 's/^.*xferlog: //' >wuxferlog
The format is the same as the wu-ftpd xferlog entries (with the leading
syslog stuff), but different from the wu-ftpd syslogged xferlog entries
because the latter is not as easy to convert into the standard xferlog
file format.
The choice to only syslog the xferlog messages rather than append to
a /var/log/xferlog file was made because the latter doesn't work to
well in the situation where the logfile is rotated and compressed and
a long-running ftpd still has a file-descriptor to the now nonexistant
xferlog file, and the log message will then get lost.

Fixes:
* In ftpd(8), clarify the -a and -c options.
* More clarifications in ftpd.conf(5).
* Ensure that all ftpd.conf commands set a parameter back to sane defaults
if an argument of `none' or bad settings are given.
* Support the `chroot' directive for `REAL' users too (for consistency).
* For `GUEST' users, store the supplied password in pw->pw_passwd for use
later in the xferlog.
* If show_chdir_messages() is given a code of -1, flush the cache of
visited directories. Invoke show_chdir_messages(-1) in end_login().
* Only syslog session stats if logging is requested.
* Rename logcmd() -> logxfer(), and dolog() -> logremotehost().
* Use cprintf() instead of fprintf() where appropriate.
* Minor KNF, and make a couple of functions static that were declared static.
