  -----------
  [lldb] [Process] Introduce protocol extension support API

Introduce a NativeProcessProtocol API for indicating support for
protocol extensions and enabling them.  LLGS calls
GetSupportedExtensions() method on the process factory to determine
which extensions are supported by the plugin.  If the future is both
supported by the plugin and reported as supported by the client, LLGS
enables it and reports to the client as supported by the server.

The extension is enabled on the process instance by calling
SetEnabledExtensions() method.  This is done after qSupported exchange
(if the debugger is attached to any process), as well as after launching
or attaching to a new inferior.

The patch adds 'fork' extension corresponding to 'fork-events+'
qSupported feature and 'vfork' extension for 'vfork-events+'.  Both
features rely on 'multiprocess+' being supported as well.

  [lldb] [gdb-remote server] Introduce new stop reasons for fork and vfork

Introduce three new stop reasons for fork, vfork and vforkdone events.
This includes server support for serializing fork/vfork events into
gdb-remote protocol.  The stop infos for the two base events take a pair
of PID and TID for the newly forked process.

  [lldb] [llgs] Support owning and detaching extra processes

Add a NativeDelegate API to pass new processes (forks) to LLGS,
and support detaching them via the 'D' packet.  A 'D' packet without
a specific PID detaches all processes, otherwise it detaches either
the specified subprocess or the main process, depending on the passed
PID.

  -----------
  [lldb] [Process/Linux] Report fork/vfork stop reason

Enable reporting fork/vfork events to the server when supported.
At this moment, this is used only to test the server code, as real
client does not report fork-events and vfork-events as supported.
