[PATCH v2 0/4] rebase/progress: add and use term_clear_line()

["SZEDER Gábor" <szeder.dev@gmail.com>]

This is a reworked/extended version of the single patch "rebase: fix
garbled progress display with '-x'" at:

  https://public-inbox.org/git/20190430142556.20921-1-szeder.dev@gmail.com/T/#u

Changes:

  - Add a helper function to clear the whole line on the terminal,
    using an ANSI escape sequence on capable terminals and a
    terminal-width worth of spaces on dumb terminals.

  - Use this helper when fixing rebase's garbled progress display with
    '-x'.

  - Use this helper in progress.c:display() as well to get rid of
    quite some arithmetic that made a -rc-phase bugfix necessary.

I don't really like the necessary adjustments to the tests in patches
3 and 4, though.
