Subject: [PATCH 3/3] gui/term.cc: close the debugger pty after curses has
 shut down

bx_term_gui_c::exit() closed the pty master before tearing curses down, so
every sequence endwin() still wanted to send - the screen clear, the cursor
restore and exit_ca_mode - was written to a closed descriptor and lost. The
terminal attached to the pty was left with the last frame of the guest on
screen and the cursor still hidden. The FILE* from fdopen() was never
closed either.

Keep the FILE* around and hand it to fclose() after endwin(), which flushes
what is left and closes the descriptor with it. If fdopen() failed the pty
is still ours, so close it directly.

Upstream-Status: Accepted [https://github.com/bochs-emu/Bochs/pull/903]
