SafeTP 1.46 patches/info

Note that SafeTP 1.46 doesn't compile with gcc-3.x, which is the primary reason to upgrade to 1.50.

Patches:

• This patch lets sftpd-1.46 compile under OpenBSD and Irix.
• This patch lets you specify a file with usernames and IP addresses, and restricts access accordingly. Also see the README.
• This patch makes sftpc accept any 1xx code at the start of a file transfer, instead of insisting upon 150.
• This script is someone's attempt to get sftpc to be usable noninteractively. Caveat emptor.
• This patch adds an option to sftpd to specify a specific data port to bind to for active (PORT command) transfers.
• This patch fixes a problem with sftpc's ability to chdir into directories which have spaces in their names. (There are other problems with names with spaces that this doesn't fix...)
• This patch fixes a bug which causes sftpd to hang whenever the system uptime is greater than 248 days. This is a critical fix for people running long-uptime servers on Unix systems.
