Use ui_file_as_string in gdb/guile/
gdb/ChangeLog:
2016-11-08 Pedro Alves <palves@redhat.com>
* guile/scm-breakpoint.c (gdbscm_breakpoint_commands): Use
ui_file_as_string and adjust to use std::string.
* guile/scm-disasm.c (gdbscm_arch_disassemble): Likewise.
* guile/scm-frame.c (frscm_print_frame_smob): Likewise.
* guile/scm-type.c (tyscm_type_name): Use ui_file_as_string and
adjust to use std::string. Throw exception directly instead of
returning it in EXCP output parameter.
(tyscm_print_type_smob, gdbscm_type_print_name): Adjust to
tyscm_type_name interface change.
* guile/scm-value.c (vlscm_print_value_smob, gdbscm_value_print):
Use ui_file_as_string and std::string.
