since libc rand() returns a signed int, there were frequently problems with

A long refactoring session yielded the following.
...
Technical changes:
* Factored out file specific information from the file descriptor
structure into a new file structure.
- Useful file metadata can be stored after the file is closed.
- File descriptors become much smaller.
- Significantly reduces the need to scan for the file end.
* Use correct types in all function signatures.
* Removed the directory cache.
Results:
* Enormous speed increase when opening cached files (10x-20x.)
* Multiple fd:s pointing to the same file have the correct semantics.
* About 100 bytes smaller ROM size.
* Slightly smaller static RAM size.

A new experimental network primitive called an 'announcement'. An
...
announcement is an (ID, value) tuple that is disseminated to local
area neighbors. An application or protocol can explicitly listen to
announcements from neighbors. When an announcement is heard, a
callback is invoked.
Announcements can be used for a variety of network mechanisms such as
neighbor discovery, node-level service discovery, or routing metric
dissemination.
Application programs and protocols register announcements with the
announcement module. An announcement back-end, implemented by the
system, takes care of sending out announcements over the radio, as
well as collecting announcements heard from neighbors.
