The debugger wire handler is implemented similarly to the io event handler.
A dedicated thread monitors the debugger port for incoming connection
requests. When a debugger is connected, the VM sends events messages
over the wire and handles debugger requests.
To start the VM with a debugger connection, use the option
--debug:<portnumber>. The VM pauses at the beginning of main()
and waits for a debugger to connect.
Subsequent changes will implement debugger commands one by one.
With this change, the VM only understands "resume" commands.

../runtime/vm/object.cc:7149: error: unimplemented code
Abort
in standalone tests when run with 64bit dart.
The ioctl function when used with FIONREAD was being passed a 64 bit
argument which is incorrect.
Documentation on ioctl:
FIONREAD
The FIONREAD ioctl returns the number of data bytes (in all data
messages queued) in the location pointed to by the arg parameter. The
ioctl returns a 32-bit quantity for both 32-bit and 64-bit
application., Therefore, code that passes the address of a long
variable needs to be changed to pass an int variable for 64–bit
applications.
