* dist/common/base: fix taking member of packed struct warning

* trace: removed outdated folder

* lib/simbricks/nicbm/multinic: fixed boost bind warning

* sims/net/pktgen/pktgen: removed forward_pkt and potential use

The doc string says to return 1 in the case of an unnecessary sync, which the implementation actually doesn't do. It instead considers an unnecessary sync as success, which is generally also the intended behavior.

besides main time, we now also print in and out timestamp of the underlying SimBricks interfaces

Check the length of socket paths in SimbricksBaseIfListen and
SimbricksBaseIfConnect. If the length exceeds the size of sun_path in
the sockaddr_un struct, we fail with a meaningful error message.

This resolves #42.

This enables other environments (in other code bases) to use a different
definition or disable the checks. Came up in the context of Simics.

This protocol is for basic read-write memory bus connections.

Extend SimbricksBaseIfInit with a sanity check to catch
misconfigured parameters where the synchronization interval
is configured larger than the link latency, which leads to
incorrect behavior.

make lint should pass again now

Stops enqueuing messages but keeps synchronizing with the network

Includes setting a terminated flag and a call to detect this.

This will be used for orderly termination of simulators at different times
without blocking others.

Empty structs are not standard C and sizeof for them in gcc is zero but for c++
is 1.

SimBricksBaseIfEstablish handles parallel connections and handshakes on
multiple simbricks connections.

This can help break ties consistently when multiple events have the same
timestamp.

Also splits out arg parsing from running so code can use the mac address in
initializationg before calling run.

Determines how much shm a particular connection will need based on the
parameters..

libsimbricks combines the base, pcie, and network libraries in one
archive.

High-level idea is to separate a out a base-protocol and library that
the PCIe and network protocols layer over. The base-protocol includes
synchronization and the basics of setting up queues, and transferring
messages. So this will enable us to build protocol-agnostic pieces like
proxies, loggers etc. A secondary goal down the line is to remove the
fixed roles of  "nics listen on pcie & network" while hosts and networks
connect, instead making this dynamic.

Unfortunately this is a big change touching just about every piece
interfacing with simbricks. So this is also consolidating and
restructuring our simbricks libraries and adapters, reducing copying of
code etc. After this commit all simulators, ours and external ones, are
broken till the respective commits fixing them.

set is broken if multiple events have the same timestamp (even though
the actual set members are pointers to the event :-/)
