786414e8e9 don't emit unnecessary info into crash log 
This was necessary because there was a bug in log offset calculation.
Not the bug is fixed and the additional output makes it harder to grep logs.

9a3bf1a7c7 open /proc/cover only once in executor 
First, it is just not necessary to open it multiple times.
But more importantly a program can close fds that it previosuly used:

r0 = open(...)
close(r0)
close(r0)

and this can close cover fds created in threaded mode.

62ed8ca7b6 don't trim programs on syscall that gives new coverage 
Threaded execution mode can execute following syscalls and they can affect
coverage of the call in question. Trimming should be handled by minimization.
