This changes the terminology to use layer instead of DIF and deprecate
the word "shim" for the IPCPs that attach to Ethernet LLC and UDP .The
terminology has not yet been changed in the variable names etc.
This reflects the design choices in Ouroboros to make IPCPs pure
resource allocators instead of also providing an "IPC service". The
Ouroboros IPCPs that attach to Ethernet and UDP implement the
allocator and are thus not really shims.

The eth_llc_data_fini function should be statically defined. Also
fixes some indentation in the CMakeLists.txt file.

This will remove google protocol buffers from the shim-eth-llc. It now
uses packed structs, as supported by the compilers of choice.

This fixes the IRMd thinking a shim-eth-llc is available after it is
disabled by configuring Ouroboros using ccmake.

Variable in cache need to be explicitly unset else they will remain in
the cache and still be defined by #cmakedefine.

This adds three build types, DebugASan, DebugTSan and DebugLSan that
enable the Address, Thread and Leak Sanitizer by setting the fsanitize
flag to the compiler. This option is supported by both gcc and clang.

This commit deprecates ouroboros_init and ouroboros_fini and adds them
as a constructor or destructor, causing these function to be run
automatically when a program that links to the library calls and exits
main(). For this to fully work, the library had to be split so that we
can avoid the irmd calling these functions (the IRMd has to create the
shm structures on which these calls depend).
The library is split in 3 parts: libouroboros-dev, libouroboros-irm
and libouroboros-common. The latter is linked to the other two so that
including libouroboros-dev or libouroboros-irm will also link
libouroboros-common.

The LLC shim was not being built even though it should be build. This
is due to CMake behaviour that when you set a var in the parent scope,
it is not set in the local scope. It also adds back THIS_TYPE to the
shim-eth-llc.

This revises the build system to have configuration per system
component. System settings can now be set using cmake.
The standard compliance defines were removed from configuration header
and are set in the sources where needed. Also some small code
refactors, such as moving the data for shims out of the ipcp structure
to the respective shims were performed.

This adds support reading Ethernet frames using the Berkeley Packet
Filter (BPF). Ouroboros now fully runs on OS X Sierra.

This adds support for libgcrypt. If at least version 1.7.0 of
libgcrypt is present, it may be used for secure random number
generation and is used for hashing in the irmd/ipcp.
The hash definitions are moved to the internal hash.h header, and
defined independently of the hashes that are defined as part of the
directory policy for the normal IPCP. The translation is moved from
the IRMd to ipcpd/ipcp.h. The bootstrap call from the IRMd expects the
IPCP to return the correct hash algorithm with a dif_info struct,
which is in line with the behavior of the enroll call.
This also improves how some platform checks in the build system are
handled.

This adds the STATUS variable to the message() call in CMakeLists.txt
in places where it was missing. This ensures that the message is
printed to stdout instead of stderr.

The protobuf include directory was not being correctly handed to the
compiler when building. Now the include directory is added
project-wide. And the protobuf package is searched for only once.

paths cannot start with "/" or PREFIX will be omitted. PREFIX must be
set before the project() call.

The installation prefix was taking a trailing backslash, while it is
common not to do so. Fixed it so that any trailing backslash is
removed by the compilation and installation scripts.

This sets the correct install directories for all the binaries,
library and header files. It also sets the right permissions on the
sockets and shared memory so that regular users can also use the
ouroboros library. Root privileges are required to run the irmd.

This adds a shim over LLC over Ethernet. It uses the raw socket API to
send messages directly over an interface.
