Changes:
* New module `rep.util.md5', has two functions for generating MD5
message digests (of files or strings)
* Changes to the `rep.io.sockets' function:
In the `socket-server' function the HOST and/or PORT arguments may
be false, meaning to listen on all addresses and to choose a
random unused port.
New functions `socket-peer-address' and `socket-peer-port', these
always returns the details of the far end of the connetion.
`socket-address' and `socket-port' have been changed to always
return the details of the local connection point.
* New function in `rep.system' module, `crypt'. A wrapper for the
system's `crypt' function (if it has one)
* New function in `rep.threads' mdoule, `make-suspended-thread'
* New module `rep.net.rpc', provides a text-stream based RPC
mechanism for Lisp programs. Similar in some ways to untyped CORBA.
(This is still in the experimental stage - its interface may
change in forthcoming releases)
* New functions in `rep.data' module, `list->vector' and
`vector->list'
* New macro `define-special-form'. A combination of `defvar' and
`setq' - it always makes the variable special and it always sets
it to the given value
* New module `rep.test.framework' implementing `assert', `check' and
`test' macros. This provides a framework for implementing unit
tests in Lisp modules (such that running the interpreter with the
`--check' option will run all tests that have been set up to be
autoloaded
