c4d43f4773 pkg/osutil: don't leace runaway processes 
When manager is stopped there are sometimes runaway qemu
processes still running. Set PDEATHSIG for all subprocesses.
We never need child processes outliving parents.

4f3b40072c dashboard/app: poll email at test end 
We currently check that there are no pending emails left on test end.
But since we don't poll, there still can be non-delivered emails.

bbbea5a373 pkg/report: pass report as []byte to isCorrupted 
We always pass report/log as []byte.
Pass it here the same way for consistency and to avoid
unnecessary large memory allocation/copy.

4bd78cef05 pkg/report, pkg/repro, syz-manager: name crash attributes consistently 
We currently have several names for crash attributes, which is disturbing.
E.g. crash title is called "Title" or "Desc". Name them consistently.

Title - single line bug identity.
Report - whole crash text.
Log - whole fuzzer/kernel output.

82b3b903a0 pkg/report: make isCorrupted linux-specific

Name can collide with other OSes. Make is linux method.

10112655d7 vm: remove needOutput arg for MonitorExecution 
Always wait 10 secs for output.
If anything this can only lead to missed crashes during repro.
Let's unify manager and repro behavior.

7a53e7e35d pkg/report: combine report data into a struct 
Parse returns 5 variables now. Later we may want to add crash "priority".
Introduce Report struct that holds all report data.

e0a2b1953b vm: merge "not executing programs" into "no output" 
Frequently it's the same condition.
In one case there is just a stray error message on console
that turns the crash into "not executing programs".
While in another case there is no stray message,
and then it's detected as "no output".

dd1609f876 executor: proceed even if /dev/net/tun is not available 
For some racy bugs syzkaller can generate a C reproducer with tun
enabled, when it's not actuallly required to trigger the bug.
Some kernel developers (that don't have CONFIG_TUN=y on their setups)
complain about such C repros.
When tun is not available, instead of exiting, print a message that tun
initialization failed and proceed.

a2c64463a2 execprog: correctly handle fault injections 
syz-execprog doesn't utilize info about fault injections from a prog log.
Since syz-execprog is used by the repro package to reproduce crashes,
crashes caused by fault injections might not reproduce.

8f3e774b76 syz-ci: improve commit matching 
1. Fetch last 200K commits instead of commits for past year.
For merged commits both author date and commit date can be
arbitrary long in past (e.g. we got a commit dated by 2014).

2. Strip some commit prefixes from commits.
We have some trees where backports are prefixed with "BACKPORT:".
Previously we could no match such commits.
