[CRIU] [PATCH 3/7] parasite: Add init_thread() helper

[Cyrill Gorcunov]

The patch adds init_thread() helper function which is supposed to
be called from seized threads context to save thread specific data
in parasite memory slab.

At moment only blocked signals are saved but it might be extended
in future.

Note it's done in a manner of main init() parasite function -- once
thread is seized we save old blocked signals mask and mask all signals
until fini() called.
