Remove superfluous paragraph macro.

fgets(3) returns a pointer, so compare against NULL, not integer 0.

Reencode files from latin1 to UTF-8.

This makes a tiny percentage of entries in calendars ugly for latin1
users, but fixes them for UTF-8 users.

This badly needs a solution involving locale-dependent re-encoding.

Implement the rename query, for when a file with the same name as the one
about to be extracted already exists. The question, and interpretation
of the response is deliberately compatible with Info-Zip.

This change was originally obtained from NetBSD, but has three changes:
- better compatibility with Info-Zip in the handling of ^D
- Use getdelim() rather than getline()
- bug fix: != changed to == in the "file rename" code

I suspect the latter is also a bug in NetBSD, but I can't easily confirm
this.

Welcome unzip(1), a pure BSD drop-in replacement for ports/unzip. In its
current state, it can handle all but four of the 991 zip files (including
jar files) I was able to identify in the ports tree. The remaining four
are two self-extracting archives and two which have garbage preceding the
first local header. This limitation is a feature of libarchive(3) which
I am currently working to resolve.

The code is unnecessarily large due to the need to emulate the exact
command-line syntax and behaviour of ports/unzip. My initial incompatible
implementation was one quarter the size of the one I am committing here.
