[PATCH 0/4] Fix a set of terminal/readline handling bugs/crashes

- Authentication-results: sourceware.org; auth=none
This series fixes a couple terminal/readline handling bugs that result
in GDB crashing with:
readline: readline_callback_read_char() called with no handler!
Aborted (core dumped)
$
... and also a bug where we lose the "&" when repeating background
commands.
Because the these won't trigger without target-async, the first two
are user-visible regressions in 7.8, which has async by default (7.7
didn't). As such, I'd like to include these in 7.8.1.
For last one (gdb/17471), I'm a bit borderline (re. 7.8.1).
Technically, it isn't really a regression, but still annoying (see
gdb/17300). If you'd prefer not having that in 7.8.1, please do speak
up.
Tested on x86_64 Fedora 20, native and gdbserver.
