Sanitize code before merging

[kyrsjo]

Remove unnecessary write( * , * ), check comments, error escapes^1 etc. There is a pile in dynk_setvalue(), which are called always (error or not). It should at least be wrapped in "if (ldynkdebug) then / end if". I might also have left some around.

[1] Includes fixing that write( * , * ) doesn't work from recursive functions

Staying away from dynk_setvalue until #2 is resolved.

[kyrsjo]

Fixed the write(,) not working - problem was that you can't call write from a function which is called from write - i.e.
write (,) f(x)
where function f(x) contains a write(,) doesn't work - the first write blocks the output buffer (sets a mutex), and the second write waits until the first write releases the mutex, which of course never happens.
