[CRIU] [PATCH 0/6] use core->tc->signals_s and core->thread_core->signals_p 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 signals_* are found.

Ruslan Kuprieiev (6):
  protobuf: add signal_queue_entry
  restore: open cores for each thread early and store them at
    current->core
  restore: use signals_s and signals_p to prepare signals
  dump: allocate task cores in collect_task() instead of
    parasite_infect_seized()
  dump: dump signals into signals_*
  image: mark CR_FD_SIGNAL and CR_FD_PSIGNAL as obsoleted and don't
    create signal-s.img
