3821b3423e scm: Unweave fds mess 
Currently criu built with criu/pie-util-fd (which
is a symlink to criu/pie/util-fd) with same flags
as we use in general compel infection code. Moreover
the criu link with libcompel.a, so we get a problem
where send_fds/recv_fds are multiple defined. Lets
rather unweave this mess:

 - drop criu/pie-util-fd.c completely
 - move send_fd/recv_fd inliners into scm.h

cbe24fb9c4 compel: Move in parasite engine 
This is the final patch in the series. It does a bunch
of renames and fixes headers respectively.

1a30731b1f compel: Add callback-based log engine 
pr_out is only special left in piegen engine, the rest use
compel's pr_x output. Probably we will need to enhance it
one day to make same close to what we have in criu.

084b0fb0ec compel/handle-elf.c: handle R_PPC64_REL32 
When compiled with clang-3.8 on ppc, compel complains:

>   GEN      criu/pie/parasite-native-blob.h
> parasite_native_blob: Error (compel/src/lib/handle-elf-host.c:541):
> Unsupported relocation of type 26

Look into R_PPC64_REL64/R_PPC64_ADDR64 and handle 32-bit the same way.

travis-ci: success for PPC+clang compile fixes

f20a124269 compel: Build host program 
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.

3b0c8dbd48 compel: Reshuffle the directories structure 
Here we rather suffle source code into directories
preparing ground for future work.

Basically all this files movements should end up in the
following compel/ tree structure

compel/
├── arch
│   ├── aarch64
│   │   ├── plugins
│   │   │   └── std
│   │   └── src
│   │       └── lib
│   ├── arm
	...
│   ├── ppc64
	...
│   └── x86
	...

	This is architectural part, where each arch consists of
	plugins/, and src/. src/ stands for code needed by compel
	cli + lib

├── include
│   ├── compiler.h -> ../../criu/include/compiler.h
│   ├── elf32-types.h
│   ├── elf64-types.h
│   ├── int.h -> ../../criu/include/asm-generic/int.h
│   ├── piegen.h
│   ├── shmem.h
│   └── uapi
│       ├── compel.h
│       └── plugins.h

	Common includes + uapi

├── plugins
│   ├── fds
│   ├── shmem
│   └── std

	Plugins source code

└── src
    ├── lib
    │   ├── handle-elf-32.c -> handle-elf.c
    │   ├── handle-elf-32-host.c -> handle-elf-32.c
    │   ├── handle-elf.c
    │   └── handle-elf-host.c -> handle-elf.c

	compel library

    ├── main.c
    ├── main-host.c -> main.c

	compel cli

    └── shared
        └── fds.c

	shared code between plugins and compel cli

Note: cross-compile won't work for a while.
