[CRIU] [PATCH 0/7] use core->thread_core->signals instead of signal-p/s*.img

[Ruslan Kuprieiev]

Currently shared and private signals are stored in signal-p/s*.img.
In order to minimize the number of imgs, lets use core*.img to store signals.
This patch saves backward compatibility, so criu will be able to use
signal-p/s*.img if no core->thread_core->signals is found.

Ruslan Kuprieiev (7):
  protobuf: siginfo.proto: add signal_queue_entry
  protobuf: siginfo.proto: add signals_entry
  protobuf: add signals entry to thread_core_entry
  restore: open cores for every thread early and store them at
    current->core
  restore: restore signals from core->thread_core->signals, if available
  dump: allocate task cores in collect_task() instead of
    parasite_infect_seized()
  dump: dump signals into core->thread_core->signals
