Before:

xz-compressing dist/fennec/assets/x86/libxul.so with "xz -zkf dist/fennec/assets/x86/libxul.so --threads=1 --x86 --lzma2=dict=8MiB,lc=3,lp=0,pb=2,mode=normal,nice=64,mf=bt4,depth=0"...

This directory contains common Python code.

The basic rule is that if Python code is cross-module (that's "module" in the
Mozilla meaning - as in "module ownership") and is MPL-compatible, it should
go here.

What should not go here:

* Vendored python modules (use third_party/python instead)
* Python that is not MPL-compatible (see other-licenses/)
* Python that has good reason to remain close to its "owning" (Mozilla)
  module (e.g. it is only being consumed from there).
