[issue23135] import searchpaths as arguments

Thanks for the feedback. The technical arguments convinced me not to spend more 
time on this. I admit this patch is kind of an ugly hack. The effort needed for 
a technically satisfactory solution seems too much for this unimportant feature.

[issue23135] import searchpaths as arguments

[c2621566]

New submission from c2621566:

This patch allows specifying import searchpaths as `-p path` arguments to the 
interpreter, without touching environment variables.

Avoiding environment variables simplifies a script of mine and is a portable 
way of swapping module implementation without touching the importing script.

e.g.
# python -p ~/.bin/customlib -p ~/.bin/other script.py
is equivalent to
# PYTHONPATH=~/.bin/customlib:~/.bin/other:$PYTHONPATH python script.py
similarly to
# ghci -i.bin/customlib:.bin/other foo.hs

It is implemented by prepending the arguments to sys.path in Py_Main just after 
Py_Initialize is called.
