bpo-38112: Compileall improvements (GH-16012)

* Raise the limit of maximum path depth to actual  recursion limit

* Add posibilities to adjust a path compiled in .pyc  file.

Now, you can:
- Strip a part of path from a beggining of path into compiled file
   example "-s /test /test/build/real/test.py" → "build/real/test.py"
- Append some new path to a beggining of path into compiled file
   example "-p /boo real/test.py" → "/boo/real/test.py"

You can also use both options in the same time. In that case,
striping is done before appending.

* Add a possibility to specify multiple optimization levels

Each optimization level then leads to separated compiled file.
Use `action='append'` instead of `nargs='+'` for the -o option.
Instead of `-o 0 1 2`, specify `-o 0 -o 1 -o 2`. It's more to type,
but much more explicit.

* Add a symlinks limitation feature

This feature allows us to limit byte-compilation of symbolic
links if they are pointing outside specified dir (build root
for example).
