[PATCH] 689458 - Crash when copying variable value

[Dodji Seketeli <dodji seketeli org>]

Hello,

When the user right clicks on a variable and selects the 'copy variable
value' menu, we are getting an embarrassing crash with the message:

    symbol lookup error:                                                         
    /usr/lib/nemiver/plugins/dbgperspective/libdbgperspectiveplugin.so: undefined     
    symbol:                                                                           
    _ZN7nemiver14debugger_utils19dump_variable_valueERNS_9IDebugger8VariableEiRSs

This is because a variant of dump_variable_value with a non-const
IDebugger::Variable& parameter is exposed in the
src/dbgengine/nmv-debugger-utils.h, is eventually used, but is not
defined.  Only the variant of dump_variable_value with a const
IDebugger::Variable& parameter is defined in
src/dbgengine/nmv-debugger-utils.cc.

The patch below fixes this by adding a const qualifier to the
IDebugger::Variable& in the dump_variable_value declaration in
src/dbgengine/nmv-debugger-utils.h.

Tested and applied to master.

	* src/dbgengine/nmv-debugger-utils.h (dump_variable_value): Make
	the variable parameter const, as in the definition.
