tests: add 'f' tool for cross platform file operations in the tests

This tool is like the collection of tools found in a unix environment but are
cross platform and stable and suitable for our needs in the test suite.

The main reason it is "needed" now is for hexdump of revision branch cache to
keep an eye on how it changes and make sure the format is stable.

It is a very generic tool that can end up being used a lot in tests, so I gave
it very generic name.

  $ hg init

  $ echo "added file2" > file2
  $ hg add file1 file2
  $ hg commit -m "added file1 and file2"

  $ echo "changed file1" >> file1
  $ hg commit -m "changed file1"
