Dmitry Safonov 0723c8a6f1 compel/uapi: remove compat_sigset_t type 
Remove compatible sigset structure: as it has the same size for both
32-bit and 64-bit, I didn't use it across the code, only for a size check.
The check is removed as we use now only k_rtsigset_t.
Wordsize for sigset is changed to 64-bit - as it's written in comment
for possible 32-bit native building.

If we ever going to support compat mode for other archs, we will
need to re-introduce compat_sigset_t type if it has for those archs
different sizes for compat/native builds.
But for a while, let's simplify this.

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
