A port of the Illumos Crypto Framework to a Linux kernel module (found
in module/icp). This is needed to do the actual encryption work. We cannot
use the Linux kernel's built in crypto api because it is only exported to
GPL-licensed modules. Having the ICP also means the crypto code can run on
any of the other kernels under OpenZFS. I ended up porting over most of the
internals of the framework, which means that porting over other API calls (if
we need them) should be fairly easy. Specifically, I have ported over the API
functions related to encryption, digests, macs, and crypto templates. The ICP
is able to use assembly-accelerated encryption on amd64 machines and AES-NI
instructions on Intel chips that support it. There are place-holder
directories for similar assembly optimizations for other architectures
(although they have not been written).

Issue #4329
Adding VPATH support, commit 47a4a6f, required that a `src`
and `obj` line be added to the top of the Makefiles. They
must be removed from the Makefiles when builtin.

ZFS depends on EFI_PARTITION, ZLIB_DEFLATE and ZLIB_INFLATE, but when
ZFS is integrated with the kernel source tree, menuconfig does not
enforce these dependencies. This can cause build failures in the case of
ZLIB_DEFLATE and ZLIB_INFLATE where symbols are not found. This can also
cause runtime failures in the case of EFI_PARTITION, where the kernel
will not understand GPT partitions when creating pools from raw disks.
We solve this by making menuconfig aware of these dependencies.

Closes#854
This commit introduces a "copy-builtin" script designed to prepare a
kernel source tree for building ZFS as a builtin module. The script
makes a full copy of all needed files, thus making the kernel source
tree fully independent of the zfs source package.
To achieve that, some compilation flags (-include, -I) have been moved
to module/Makefile. This Makefile is only used when compiling external
modules; when compiling builtin modules, a Kbuild file generated by the
configure-builtin script is used instead. This makes sure Makefiles
inside the kernel source tree does not contain references to the zfs
source package.
