[PATCH 2/3] Dump variable value to stderr

[Dodji Seketeli <dodji seketeli org>]

Hello,

While hacking on Nemiver lately, I have felt the need to add a new
dump_variable_value function that would serialize an instance of
IDebugger::Variable out to stderr for debugging purposes.

Tested and applying this to master.

	* src/dbgengine/nmv-debugger-utils.h (dump_variable_value):
	Declare new overload.  Make the existing overload take an
	std::ostream instead of an std::ostringstream.
	* src/dbgengine/nmv-debugger-utils.cc (dump_variable_value):
	Define new overload.  Make the existing overload take an
	std::ostream instead of an std::ostringstream.
