I manually modified the result type to be an enum.

Change the default behavior of `LTC_ARGCHK()` for Release, resp.
Release+Shared Library builds to be non-fatal.
This closes#458

There are cases where we want to use an MPI provider, but the package is
not installed in the system, so `pkg-config` can't find it.
To solve this simply ignore the errors created and only print something
if the user asks us to by passing `V=1`.

* add `ltc` wrapper script for installed demos
* rework demos/CMakeLists.txt and add some more bells and whistles
* prefix installed demos with `ltc-`
Currently this makes the standard makefiles and CMake results diverge, but
we can fix that later if required.

SM4 (formerly SMS4)[1] is a block cipher used in the Chinese
National Standard for Wireless LAN WAPI (Wired Authentication
and Privacy Infrastructure).

This is required
1. when cross-compiling
2. to enable/disable the specific compiler warnings
Tested on `bash`, `dash`, `zsh` and FreeBSD `sh`.

* use a separate `libtomcrypt` folder to install the headers to
* use `INCPATH` and `LIBPATH` when installing `libtomcrypt.pc`
* fix `libtomcrypt.pc` generation for `makefile.unix`
This fixes#625

AES implementation for the platform.
