This replaces all of the Apache blurbs at the start of each file with an `# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing uses to be consistent in capitalization, and to be placed above any copyright notices. This removes nearly 3000 lines of boilerplate from the project (only python files), which no developer cares to look at. SPDX is in common use, particularly in the Linux kernel, and is the recommended format for Meson's own `project(license: )` field

This module soly exists to work around a pathlib.resolve bug on
|
|
certain Windows systems:
|
|
|
|
https://github.com/mesonbuild/meson/issues/7295
|
|
https://bugs.python.org/issue31842
|
|
|
|
It should **never** be used directly. Instead, it is automatically
|
|
used when `import pathlib` is used. This is achieved by messing with
|
|
`sys.modules['pathlib']` in mesonmain.
|
|
|
|
Additionally, the sole purpose of this module is to work around a
|
|
python bug. This only bugfixes to pathlib functions and classes are
|
|
allowed here. Finally, this file should be removed once all upstream
|
|
python bugs are fixed and it is OK to tell our users to "just upgrade
|
|
python".
