This removes restorer.h from infect. The header describes
routines, structures and constants messing with restorer blob.

This is
* Move parasite_setup_regs() and related into arch/infect
* Move arch_can_dump_task() into infect
* Move parasite_send_fd() into infect-util
and completes parasite-syscall.h removal.

And use it in CRIU directly instead:
- move syscalls into compel/arch/ARCH/plugins/std/syscalls
- drop old symlinks
- no build for 32bit on x86 as expected
- use std.built-in.o inside criu directly (compel_main stub)
- drop syscalls on x86 criu directory, I copied them already
in first compel commist, so we can't move them now, but
delete in place

Both std and criu will use it for syscalls sake.
Note I've to disable x86 compat mode for a while:
we have to provide native types there thus will
back once everything else is complete.

The default compel binary is the one compiled for target architecture.
The compel-host one is compel compiled for current arch that is needed
to build something for target arch.
We could use default compel if target arch == current arch, but this
makes things more complex.

Delete plugins/include/asm/std directory - let it be without plugin name.
Make symlinks to reuse criu's files, except those, which will
be deleted after libcompel from criu (like syscalls).

The plugin provides basic features as string copying, syscalls, printing.
Not used on its own by now but will be shipping by default with other
plugins.
With great help from Dmitry Safonov.

For tests, we need to know if elf file parsing was interrupted
in a proper place (and thus meaningful error numbers).

Split handle_elf() function from main.c to per-arch.
Rename it to handle_binary not to cross-reference.
Rename generic handle_elf to __handle_elf as with define
not to litter namespace.

I propose to change compel directory structure:
- if we want support more arch's than x86/ppc66, it seems
worth to add arch/ folder
- move all sources from src/ folder up
- to have headers and build additional object with CFLAGS for
a symlink seems for me less hacky way than mess around
with .c files cross-linking
- I made handle-elf.h header for arch helpers code. I may named
that just "elf.h", but that may confuse, as there are <elf.h>
system header
- I would like to drop those ELF_PPC64/ELF_X86_32/ELF_X86_64
defines and use CONFIG_X86_64 and whatnot
After this patch compel directory become:
compel/
├── arch
│ ├── ppc64
│ │ └── include
│ │ └── handle-elf.h
│ └── x86
│ └── include
│ └── handle-elf.h
├── handle-elf-32.c -> handle-elf.c
├── handle-elf.c
├── include
│ ├── piegen.h
│ └── uapi
│ ├── elf32-types.h
│ ├── elf64-types.h
│ └── types.h
├── main.c
└── Makefile
Note: temporary I make value32 and addend32 for compilation on arm/aarch64
