Tom de Vries 86fe51fcc7 [gdb/testsuite] Reimplement gdb.gdb/complaints.exp as unittest
When building gdb with "-Wall -O2 -g -flto=auto", I run into:
...
(gdb) call clear_complaints()^M
No symbol "clear_complaints" in current context.^M
(gdb) FAIL: gdb.gdb/complaints.exp: clear complaints
...

The problem is that lto has optimized away the clear_complaints function
and consequently the selftest doesn't work.

Fix this by reimplementing the selftest as a unit test.

Factor out two new functions:
- void
  execute_fn_to_ui_file (struct ui_file *file, std::function<void(void)> fn);
- std::string
  execute_fn_to_string (std::function<void(void)> fn, bool term_out);
and use the latter to capture the complaints output.

Tested on x86_64-linux.

/* ***DEPRECATED*** The gdblib files must not be calling/using things in any

present or not) must be used and set to the appropriate routine by any
command language that cares about it. If you are having to include this
file you are possibly doing things the old way. This file will dissapear.
