This commit includes functionality to turn on
the object serializer for network communication.
This is done the following way:
- On incoming connections, a process will detect
whether the client supports the object serializer
and will only serialize responses with it, if it does
- On outgoing connections, the command line flag is used
to determine whether the object serializer should be used
to send data.
This way, a cluster can run in mixed mode. To upgrade one
can upgrade one process at a time and set the flag one process
at a time.
This is how this is tested on the simulator:
- The command line flag can take three options: on, off,
and random.
- For off, the object serializer will never we used.
- For on, the object serializer will be always used.
- For random, the simulator will flip a coin for each
process it starts up.
- This patch will make FDB listen to multiple addresses given via
command line. Although, we'll still use first address in most places,
this patch starts using vector<NetworkAddress> in Endpoint at some basic
places.
- When sending packets to an endpoint, pick a random network address in
endpoints
- Renames Endpoint::address to Endpoint::addresses since it
now holds a vector of addresses.
Extend `Endpoint` class to take multiple NetworkAddresses instead of
just one. Hence, to talk to an endpoint instead of one IP:PORT, we'll
have multiple IP:PORT pairs.
This patch simply adds the field and makes changes to compile the
codebase. The first element of of `address` field is used everywhere.
Hence the way we talk to remains same with this patch.
NOTE:
Directly accessing the first memeber of Endpoint::address is unsafe
as Endpoint() doesn't enforces non-empty address list. However, since
the correctness test pass for now and are anyway replacing all those
unsafe accesses with ones considering the whole vector, this patch
ignores to access them in safe way.
Remove the use of relative paths. A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h". Adjust so that every include references such a header with the
latter form.

This takes advantage of the new actorcompiler functionality to avoid
having duplicate definitions of `Void _` when trying to feed the
un-actorompiled source through clang.
* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.
Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.
This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.
