Subject: [PATCH] CCpp: turn off compat cores

Disable compat cores because with systemd>=229, RLIMIT_CORE is

'unlimited' by default and RLIMIT_CORE!=0 was the signal to create a

core file in the old way. So, abrt-ccpp-hook creates the old way cores

everywhere on file systems by default and users don't know about it

because they did not enable it manually via 'ulimit -c unlimited'.

We could restore the old RLIMIT_CORE value by creating a systemd

configuration file with 'DefaultLimitCORE=0' but that would not be a

good solution for our users:

* you have to reboot, otherwise the configuration has no effect

* and therefore it is impossible to set the new value when

  abrt-ccpp.service is stopped and the users who expect

  RTLIMIT_CORE='unlimited' would be confused

We should probably adopt the behaviour of systemd-coredump. However,

that means that abrtd must not drop any problem it receives and should

mark those problems that would be dropped as NOT-REPORTABLE to prevent

users from filing bug reports for unfixable problems.
