The commands towards the IPCPs have different time requirements, but
the irmd had only a single timeout value to wait for a response. This
commit allows setting different timeouts for the IRMd based on the
command, configurable globally.

This commits adds the functions and messages to specify a fixed
protocol syntax during CACEP. It also revises the messages for
specifying the DT protocol syntax from the irm tool.

The IPCP will now report the DIF name and the hash value to the IRMd
as a dif_info struct. This can later be extended to add further
capability reporting. Some bugfixes in normal.

Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.

All information passed over the IRMd/IPCP boundary for using IPC
services (flow allocation, registration) is now hashed. This
effectively fixes the shared namespace between DIFs and the IRMDs.
This PR also fixes some API issues (adding const identifiers),
shuffles the include headers a bit and some small bugs.

Setting the timeouts on flow_alloc and flow_accept will now work. This
makes some changes to the UNIX sockets used for management
communication between the APs, IRMd and IPCPs.

The flow_alloc_res and flow_alloc_resp calls have been removed. The
flow_alloc and flow_accept calls are now both blocking and take an
additional timeout argument.

Our mailserver was migrated from intec.ugent.be to the central
ugent.be emailserver. This PR updates the header files to reflect this
change as well. Some header files were also homogenized if the
parameters within the functions were badly aligned.

The AE name should not be passed over the layer boundaries. If an
application has more than one AE it should exchange this in CACEP.

This removes the logfile and outputs log messages to the logging
system. The creation of the logfiles (as well as the ap_init() call)
were moved into ipcp_init() to simplify the IPCP creation and
shutdown.

This allows IPCPs to bind a name, so that they can announce their name
to neighbors which can then allocate a flow to them. Registering of
the name happens by an administrator. It also moves the irmd_api to
common ground, since it is used by all IPCPs.

Now correctly relays the qoscube end-to-end in the stack.
A simple function specifying the cube in the spec is used for initial
testing.
The translation is now done in dev.c, but it could be moved elsewhere
when qos cabability matures and the need arises.

This corrects the license statements on all files. Installed headers
are LGPLv2.1, the rest of the code is GPLv2.

This adds the ability to query IPCPs if a name can be reached through
them, e.g. if a name is available in a DIF. This means that in the
shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like
query has been added, in the local a check is done to see if the name
is registered, and in the normal currently no application is reachable
through it.

The fast path will now use an incoming ring buffer per flow per
process. This necessitated the development of a new method for the
asynchronous io call, which is now based on an event queue system for
scalability (fqueue). The ipcpd's and tools have been updated to this
API.

IPCPs can now use ap_init() to initialize the memory. All flows are
accessed using flow descriptors, this greatly simplifies IPCP
development. Reverts the fast path to a single ap_rbuff per process.
Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev
holding tailored functions for shims. Moves the buffer_t to utils.h.
Fixes the shim-eth-llc length field. Removes the flow from shared.h.
