[PATCH v4 0/4] introduce new option `--auto-advance`

[Abraham Samuel Adekunle <abrahamadekunle50@gmail.com>]

Hello,

After after more reviews and deliberations, I have been able to
rename the new option name to `--auto-advance`, where the
--no-auto-advance implements the feature and does not auto advance
while --auto-advance is the default and maintains the current
behaviour.

With the option, users can navigate in between files while deciding
on hunks as they wish with the '>' and '<' option for going to the
next and previous file respectively if there are more than one file.

Patch 1 implements the new `--no-auto-advance` options, Patch 2
modifies the function `patch_update_file()` to instead take the index
of the file as parameter instead of the file_diff. Patch 3 moves the
'git apply' logic into a function so that we can reuse this logic when
implementing the all or none application of patches.
Patch 4 implements the interfile navigation, and adds tests to the
interactive test file.

Changes in v4:
==============
- Renamed option to `--no-auto-advance` with `auto-advance` being
  the default option
- Modified the function signature of 'patch_update_file()' to accept
  the index of the file diff
- Moved git apply logic into function for reuse
- Removed the whatnow prompt. Now the hunks in the file keep
  showing even after all hunks have been decided
- Added hunk summary to patch help remainder to show the user the
  hunk deails
- Added tests ot t3701-add-interactive.sh
