Remove the setjmp/longjmp stuff completely. Use signal
handlers to set flags only (with exception for sigquit(),
which still seems to call some non-reentrant functions on
its way to _exit(2).) That must eliminate the possibility
of catching SIGSEGV from following non-reentrant paths from
signal handlers.

Add a new option, '-o', for "Write-only". Disables the RETR command,
preventing anyone from downloading files. In conjunction with -A, and some
appropriate file permissions, this lets you create an anonymous FTP drop
box for people to upload files to.

The more obvious "-w" flag is already taken by NetBSD's ftpd. "-o" was
available as an option letter in all three BSDs.

Previous clobbered a work-in-progress. Here is the merged result:

Limit the "pathname" glob to one item, as that is what all users of it
are expecting, except for LIST.

Always glob, instead of when the first character is a ~. For example,
if you had directories ~/x1, and ~/x2, then "cwd x[1]" would fail, but
"cwd ~/x[1]" would work since it was globbed due to the ~ character.
Also, "cwd ~/x[12]" used to arbitarily work as it used the first
expansion (ie: x1) without an error. Make it return '550 ambiguous'
instead of '550 not found' so that the user can see the difference.

For LIST, just use the user supplied string as the popen does the glob.

Add the "SITE MD5 filename" facility.

This allows you to determine if the file on the other side is the same
as the one you have without transferring the entire file to compare.

Needless to say, if the server end lies to you this check doesn't work,
but on the other hand, if it lies to you about the files checksum,
what can you trust from it ?
