[GSoC][PATCH v3 0/3] Use helper functions in test script

This patch ultimately aims to replace `test -(d|f|e|s)` calls in t3600-rm.sh Previously we were using these to verify the presence of diretory/file, but we already have helper functions, viz, `test_path_is_dir`, `test_path_is_file`, `test_path_is_missing` and `test_file_not_empty` with better functionality

Helper functions are better as they provide better error messages and improve readability. They are friendly to someone new to code.

Rohit Ashiwal (3):
  test functions: add function `test_file_not_empty`
  t3600: modernize style
  t3600: use helpers to replace test -d/f/e/s <path>
