Rename Boot_Port.sendReceive to sendRecv to match real name in Port

* Port.sendRecv was shown as "Port.sendReceive" in Browser,
  which does not exist and should be "Port.sendRecv".
Merge pull request #179 from eregon/sendRecv

Rename Boot_Port.sendReceive to sendRecv to match real name in Port
Remove unused methods BoostBasedVM::setApplication{URL,Args}

* Application URL and args are put in the registry directly by emulator.cc.
Add a BoostVM class to hold what needs a VM in a Boost environment

* BoostBasedVM::boostVMFor() needs to be fixed.
  We could extend VirtualMachine or find
  another smarter way to have constant-time boostVMFor().
* UUID generation should be per vm if we want to avoid locking
  on the random generator.
* Boost classes taking a reference to a BoostBasedVM now take a BoostVM
  since they need to access BoostVM features. An alternative could be to pass
  the BoostVM as the first argument in the different methods,
  but the constructor needs it too and it is much easier with the lambdas.
Let each BoostVM run in its own thread, and the main thread do the ASIO

* We reuse the _conditionWorkToDoInVM condition variable to wait
  efficiently between VM runs since it is unused outside of run().
* Added VMs should be start()'ed but it should not be needed to call run(vm)
  on the main thread, unless the previous VMs died and we want that one
  to outlive others.
