(varobj_get_frozen): New.
(varobj_update): New parameter explicit.
* varobj.c (struct varobj): New fields frozen
and not_fetched.
(varobj_set_frozen, varobj_get_frozen): New.
(install_new_value): Don't fetch values for
frozen variable object, or children thereof. Allow
a frozen variable object to have non-fetched value.
(varobj_update): Allow updating child variables.
Don't traverse frozen children.
(new_variable): Initialize the frozen field.
(c_value_of_variable): Return NULL for frozen
variable without any value yet.
* mi/mi-cmd-var.c (varobj_update_one): New parameter
'explicit'.
(mi_cmd_var_create): Output the 'frozen' field,
as soon as testsuite is adjusted to expect that field.
(mi_cmd_var_set_frozen): New.
(mi_cmd_var_update): Pass the 'explicit' parameter to
varobj_update_one.
* mi/mi-cmds.c (mi_cmds): Register '-var-set-frozen'.
* mi/mi-cmds.h (mi_cmd_var_set_frozen): Declare.
