Fix two bugs:

- The ftpPassive() function seemed to think that the PASV command
is a toggle. This is not true (however, the ftp(1) "pass" command
is indeed a toggle). So no need to emit a "PASV" command each time
this function is called; that's handled by ftp_file_op().

- check_passive() is supposed to check if FTP_PASSIVE_MODE is defined,
and if so, override ftpPassive(). However, it was overriding
ftpPassive() even if FTP_PASSIVE_MODE was not defined, rendering
calls to the ftpPassive() function completely ineffectual.

Also, clarify the relationship between ftpPassive() and the
FTP_PASSIVE_MODE environment variable in the man page.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

For functions ftpGetURL, ftpPutURL, ftpLogin it was impossible to know
FTP error return code because
1) They return NULL, it means that ftpErrno can't be used because
it takes file pointer
2) They don't have FILE-type argument as f.e. ftpGet/ftpPut to use
it for ftpErrno instead.

For that functions I add yet one int* type argument to store
FTP error return code. It is impossible to add some global variable
for that reason, because user can have multiply FTP connections
opened at the same time.

So, interface changed, major number bumped.
Userland changes will follows.

Minor bugfixes, the code:
Forget to close file in few places, when failure occurse
Forget to NULL cached host name, multiply free is possible

delete doubled words, e.g.: "the the" -> "the"

Implement a change suggested by Archie Cobbs - the seekto argument should
be zero'd only if the operation *fails*, indicating that the file
starting offset is effectively zero. This makes more sense.

Add an ftpErrString() function for returning human readable failure
codes.

1. Add verbose flag to ftp_login()
2. Remove pkg_* support - tcl7.5's channel interface has rendered this
almost entirely unsupportable (at least in the way it currently stands).

Adjust docs to match reality.

Make certain small things more consistent with the other stdio man pages.

Stamp out a potential memory leak.
Make ftpChdir return the server status again - it was more convenient.

Rethink and reimpliment the way RESTARTS are handled. The method I inheirited
from jmz was a hopeless kludge (sorry Jean-Marc :) and handled the problem
in the wrong way. ftpRestart() has now gone away and ftpGet() has grown a
new parameter.

Whoops, give the authors all proper credit.

This commit was generated by cvs2svn to compensate for changes in r16420,
which included commits to RCS files with non-trunk default branches.

Bring in a new library `libftpio', so named to avoid clashes with older
packages and also sort of give the (correct) impression that this basically
sits on top of stdio and deals with stream pointers (FILE*).
