This actually does two things: 1. The parasite code writes to pages _or_ to pages_shared file himself based on a hint given from the main program. This avoids shared pages copying in finalize_core. 2. The private pages are moved out of the core file into a separate one. This avoids private pages copying in finalize_core. The goal of this patch is a) to avoid pages copying at all (we still have one on restore, but fixing this requires Andrey's work on shared memory dumping) and b) make big blobs with pages be stored in separate files (I have plans on its format rework and unification).

This patch adds new option -d. zdtm.sh -d ... does not do restore and instead of that it wakes up test processes after dump and check results of the test. Signed-off-by:

v2: wrappers names become less obfuscating This patch: 1) Updates function cr_fdset_open() to be suitable for handling fdset creation for dump and show stages. 2) Replaces cr_fdset_open() by new wrapper function cr_fdset_dump(). 3) Replaces prep_cr_fdset_for_restore() by new wrapper function cr_fdset_show().

If an error happens during late restore stage, we better exit with error than dive into endless loop. The loop was useful at early prototype times, but not now when we use zdtm test suite. For example, force injected error now reports | Restoring EXE (/home/crtools/test/zdtm/live/static/selfexe00) | 764 | 11308 | Error (cr-restore.c:1280): 11308 exited, status=255 | Error (cr-restore.c:1412): Someone can't be restored which is a way better than silent loop.
