remove master and naming overhaul
...
Remove master process entirely, it is not useful in its current form.
We first need to understand what we want from it, and them re-implement it.
Prefix all binaries with syz- to avoid name clashes.

use fork server in executor
...
This avoids exec per test.
Also allows to pre-map shared memory regions.
And will allow to pre-map coverage regions, etc.
Seems to work already, but probably there are still some bugs.
