8fa0c867d4 syz-fuzzer: generates hints only for the call that gave new coverage 
During smashing we know what call gave new coverage,
so we can concentrate just on it.
This helps to reduce amount of hints generated (we have too many of them).

baecf7a955 syz-fuzzer: make -v=1 logging more useful 
We currently print programs with -v=1, this leads to too verbose output.
This was used during syzkaller bootstrapping and is not so useful anymore.
Don't print programs with -v=1. Instead give more insignt into what fuzzer
is doing.

b71450d9fb executor: prevent executor from messing with output region 
When comparisons are enabled fuzzer somehow manages to discover
the output region and corrupt it. It seems to fetch the address
from some memory operations (mmap/munmap).

Don't leak the output region address.

6755f62592 syz-fuzzer: fix manager polling

we just need not request candidates if we have plenty of work.
