docs: remove obsolete doc file "codemap.txt"

I started to update this to reflect the current codebase, but then I thought (a) nobody seemed to notice that it hasn't been updated since December 2007, and (b) it will just bit-rot again, so I'm removing it.

-CODE OVERVIEW
-
-A brief map to where the code lives in this distribution:
-
- src/allmydata: the code for this project. When installed, this provides the
-                'allmydata' package. This includes a few pieces copied from
-                the PyCrypto package, in allmydata/Crypto/* .
-
-Within src/allmydata/ :
-
- interfaces.py: declaration of zope.interface-style Interfaces for most
-                components, also defines Foolscap RemoteInterfaces for
-                all remotely-accessible components
-
- node.py: the base Node, which handles connection establishment and
-          application startup
-
- client.py, introducer.py:
-   these are two specialized subclasses of Node, for users and the central
-   introducer, respectively. Each works by assembling a collection of services
-   underneath a top-level Node instance.
-
- introducer.py: node introduction handlers, client and server
-
- storageserver.py: provides storage services to other nodes
-
- codec.py: low-level erasure coding, wraps the zfec library
-
- encode.py: handles turning data into shares and blocks, computes hash trees
-
- upload.py: upload server selection, reading data from upload sources
-
- download.py: download server selection, share retrieval, decoding
-
- dirnode2.py: implements the distributed directory nodes.
-
- webish.py, web/*.xhtml: provides the web frontend, using a Nevow server
-
- uri.py: URI packing/parsing routines
-
- hashtree.py: Merkle hash tree classes
-
- debugshell.py, manhole.py: SSH-connected python shell, for debug purposes
-
- util/*.py: misc utility classes
-
- test/*.py: unit tests
-
-
-Both the client and the central introducer node runs as a tree of
-(twisted.application.service) Service instances. The Foolscap "Tub" is one of
-these. Client nodes have an Uploader service and a Downloader service that
-turn data into URIs and back again.
-
-The Uploader is given an "upload source" (which could be an open filehandle,
-a filename on local disk, or even a string), and returns a Deferred that
-fires with the URI once the upload is complete. The Downloader is given a URI
-and a "download target" (an open filehandle, filename, or instructions to
-provide a string), and fires a Deferred with a target-specific value when the
-download is complete. The source/target API is intended to make it easy to
-stream the incoming data to a media player or HTTP connection without having
-to consume a lot of memory for buffering.
