$Id$ -> $FreeBSD$

Change errno usage as a field in a structure and as an argument to a
function from 'errno' to 'error' so that there is no conflict with the
thread-safe definition of errno in errno.h.

Make this C++ safe.

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

Oops, forget the fact that several ftp connections can be active
at the same time, so add new con_state to avoid QUIT recursion

Still should go to 2.2

Make libftpio 64-bit clean.

Major version bumped (by me) since the ftpGet() public interface has
changed (an "int *" becomes and "off_t *")

Add an ftpErrString() function for returning human readable failure
codes.
Submitted-By: Archie Cobbs <archie@whistle.com>

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).

Implement an ftpVerbose() hook.

Makefile:
Add -Wall to CFLAGS

ftpio.h:
It's ftpGetModTime, not ftpModTime

Fix a bug in the way binary/ascii settings were being done. New
ftpAscii() call sets connection to ascii as counterpart to ftpBinary().

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.

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*).
