Improve MinGW support in Readline
These changes were already accepted upstream in Readline, but GDB did not yet import a newer Readline version. readline/Changelog.gdb: * util.c: Include rlshell.h. (_rl_tropen) [_WIN32 && !__CYGWIN__]: Open the trace file in the user's temporary directory. * tcap.h [HAVE_NCURSES_TERMCAP_H]: Include ncurses/termcap.h. * input.c (w32_isatty) [_WIN32 && !__CYGWIN__]: New function, to replace isatty that is not reliable enough on MS-Windows. (isatty) [_WIN32 && !__CYGWIN__]: Redirect to w32_isatty. (rl_getc): Call _getch, not getch, which could be an ncurses function when linked with ncurses, in which case getch will return EOF for any keystroke, because there's no curses window. * tilde.c (tilde_expand_word) [_WIN32]: * histfile.c (history_filename) [_WIN32]: Windows-specific environment variable to replace HOME if that is undefined. * funmap.c (default_funmap): Compile rl_paste_from_clipboard on all Windows platforms, not just Cygwin. * readline.h (rl_paste_from_clipboard): Include declaration for all Windows platforms. * display.c (insert_some_chars, delete_chars): Don't use the MinGW-specific code if linked with ncurses. * configure.in: * config.h.in: Support ncurses/termcap.h. The configure script was updated accordingly. * complete.c [_WIN32 && !__CYGWIN__]: Initialize _rl_completion_case_fold to 1. (printable_part, rl_filename_completion_function) [_WIN32 && !__CYGWIN__]: Handle the drive letter.
