This reduces the default buffer size to 4096 blocks (about 16MB). This
will avoid problems when users try a default build on smaller machines.

This fixes the access to an uninitialized dt_pci struct when updating
flow statistics in the case there is no next hop, which often resulted
in a segmentation fault.

The irmd was not cleaning up non-deallocated flows upon exit. This bug
was probably introduced with the introduction of the threadpool
managers. Also fixes a missing rwlock_destroy().

The time of establishment will be printed as part of the flow

This revises the RIB so it gets the complete file attribute list from
the component instead of setting some attributes in the library. This
will allow setting read/write access later on in the component
itself. The time of last change of lsdb entries in the file system is
now set to the time of the last received Link State Update for that
entry.

This makes the TTL non-optional and allows the maximum (initial) value
of the TTL to be specified at bootstrap (the default is set to
60). The fd in the DT PCI is now called EID (Endpoint ID). The names

respectively in all sources.

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.
