(display_gdb_prompt): Use top_level_prompt() to compute the top
level prompt, and don't notify the before_prompt observers
directly here. Always trick readline into not trying to display
the prompt if sync_execution and displaying the primary prompt.
If displaying a local/secondary prompt, always show it, even if
sync_execution is set.

input is expected, call display_gdb_prompt with an explicit empty
prompt.

on linker failure due to reference in debug or non-alloc
sections to optimized away toc entry, and don't abort.

direct call to display_gdb_prompt.
(display_gdb_prompt): Do not call observer mechanism during
synchronous execution.
