This patch adds unit tests for the isrpipe module.
The mutex used to sync the reader and writer of the pipe is initialized as unlocked. This results in a bit of wasted CPU cycles the first time a read blocks. This patch inits the mutex in a locked state so that the first blocking read blocks immediately.
This patch makes the requirement on buffer size more prominent. Additionally, it adds the missing argument to the doxygen block of the static initializer. Finally, it chanes the argument name passed to the static intializer to decouble the API from the implmentation details.
This patch documents what happens when a timeout occurs when isrpipe_read_all_timeout() has been called.

Contribution description
This PR originally started out as a fix to isrpipe's init of it's mutex, but it grew into adding unit tests and improving its doc as well. I also improved some doc for
tsrb. I can break that into a separate PR if you desire.Testing procedure
