Add support for a variable object that tries to evaluate itself in the currently selected frame, rather than in a fixed frame. * wrapper.c,h (gdb_parse_exp_1): Added a wrapper for gdb_parse_exp_1. * varobj.h: Added USE_CURRENT_FRAME to varobj_type & changed def'n of varobj_create. * varobj.c (varobj_list): Return type indicates whether the variable's type has changed (for current frame variables). (varobj_update): Handle the case where the variable's type has changed. (delete_variable_1): Allow for deletion of variables that have not been installed yet. (new_root_variable): Initialize use_selected_frame variable. (value_of_root): This is where most of the work to handle "current frame" variables was added. Most of the complexity involves handling the case where the type of the variable has changed. (varobj_create): Add a "type" argument, to tell if the variable is one of these "current frame" variables. Also protect call to parse_exp_1 from long jumping. * mi-var-block.exp: The error report from varobj_create changed since I am now trapping parse_exp_1 errors. Change the tests to match the new error message. * mi-var-child.exp: Ditto. * mi-var-cmd.exp: Ditto. * lib/gdb.exp: Fix the gdbtk_start routine to correctly find all the library directories. * gdbtk-varobj.c (variable_create): Pass the correct "how_specified" flag to the varobj_create routine.
