The flow_fini() function was marking flows as wronly (so rdonly for
the application) when the flow was deallocated. With the recent
addition of the flowdown state, we can now mark them as down. Also
fixes some bounds checks and alignment.

The event type of the current event in the fqueue can now be requested
using the fqueue_type() command. Currently events for packets
(FLOW_PKT), flows (FLOW_UP, FLOW_DOWN) and allocation (FLOW_ALLOC,
FLOW_DEALLOC) are specified. The implementation only tracks FLOW_PKT
at this point.

This makes the buffer size used by the UNIX sockets configurable. In
case of a lot of IPCPs in the system it might become too small with
the default value, resulting in irm command failures. The user can now

If a program exits, it cleans its read buffer. However, another
process could still write a packet in that buffer, which would cause
the IPCP or IRMd to run into an assertion failure on shutdown. Setting
the rbuff to ACL_FLOWDOWN prevents this.

A previous commit tried to stat the shared memory file in case it was

The reg/unreg API is simplified to registering and unregistering a
single name with a single IPCP. The functionality associated with
registering names was moved from the IRMd to the irm tool. The
function to list IPCPs was simplified to return all IPCPs in the
system with their basic properties needed for management.
The above changes led to some needed changes in the irm tool and the
management functions that were depending on the previous behaviour of
list_ipcps.
Command line functionality to list IPCPs in the system is also added
to the irm tool.
Some older code was refactored.

This allows disabling partial reads. It adds a flag FLOWFRNOPART that
disables partial reads. Partial read is different from partial
delivery (FRCTFPARTIAL), which allows delivery of fragments of an
incomplete packet and thus potentially corrupted data. FLOWFRNOPART
will never deliver corrupted data (unless FRCTFPARTIAL is also set).
If FLOWFRNOPART is set and the buffer provided to flow_read is too
small for the SDU, that SDU will be discarded and -EMSGSIZE is
returned;

This implements partial read of packets if the buffer supplied to
flow_read() is smaller than the packet in the buffer. If the number of
bytes returned by flow_read equals the size of the buffer, the next
read() will deliver the next bytes of the packet (or 0 if the packet
was exactly the size of the buffer on the previous read).
Implements #7.

This adds an IPC Process that uses DIX Ethernet with an Ethertype that
is configurable at bootstrap. This allows parallel DIX layers over the
same Ethernet network with different Ethertypes (and one LLC
layer). It allows jumbo frames in the future, and should avoid the
problems we have with some routers not handling LLC traffic very
well. The destination endpoint ID is sent as a 16 bit integer, so the
maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes
when Jumbo frames are used.
The implementation is very similar to the Ethernet LLC IPCP, so it is
implemented using preprocessor macros in the single source instead of
duplicating code.

The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but
the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE
clock. This causes the blocking reads not to timeout correctly.

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.

This replaces the variable FRCT header with a packed struct, which
significantly simplifies the implementation. The shm_du_buff calls to
release the head/tail are updated to return a pointer to the original
head or the new tail (in symmetry to the alloc calls, which return a
pointer to the new head and old tail), so that it immediately points
to the structure that is needed.
The frct_pci sources are removed and frct is now fully in the frct.c
source file.

The frct_pci and rq headers are moved from include/ouroboros to
src/lib since they are only needed in the library. FRCT is moved to
its own source file.
FRCT takes the application PDUs, encapsulates and processes them and
hands them back. This makes it easier to disable FRCT should the
application want to write to a "raw" flow. An FRCT instance is now
allocated upon alloc and released upon dealloc.
The FRCT data structure is split into a sender and receiver connection
record. Setting a new configuration will now be done upon sending the
next data PDU, which will flag the DRF for a new run and use that
configuration. This avoids some issues should packets arrive
out-of-order, and simplifies setting a configuration.
