Michał Górny bdb4468d39 [gdb-remote] Move broadcasting logic down to GDBRemoteClientBase
Move the broadcasting support from GDBRemoteCommunication
to GDBRemoteClientBase since this is where it is actually used.  Remove
GDBRemoteCommunication and subclass constructor arguments left over
after Communication cleanup.
