Rename Package serial -> serial_labgrid

[Bastian-Krause]

labgrid's pyserial fork uses the same package name as the original pyserial. This becomes a problem once another dependency pulls in the original pyserial. Then one package will overwrite the other.

Thus, rename the package from "serial" to "serial_labgrid":

• pyproject.toml edited manually
• pip install rope, then run:

import rope

project = rope.base.project.Project(".")
serial = project.find_module("serial")

changes = rope.refactor.rename.Rename(project, serial).get_changes("serial_labgrid")
project.do(changes)

• update serial.urlhandler -> serial_labgrid.urlhandler in serial_labgrid/__init__.py:protocol_handler_packages

This is the first step to fix labgrid-project/labgrid#1245.

This prevents distributions from using a correctly patched upstream pyserial. I am less in favor of merging this because of that reason.

For the record: @Emantor means these import changes that will be needed in labgrid:

import serial -> import serial_labgrid
import serial.rfc2217 -> import serial_labgrid.rfc2217

Since the pyproject.toml already references this fork, a patch would be required anyway (at least if the distro uses that somehow). As far as I know, nixos is the only distro packaging a recent labgrid version.

Alternatives to this PR are:

• make sure our pyserial fork is overwriting pyserial (not the other way around), but that means other pyserial dependencies will be silently ignored (e.g. a package requiring pyserial>=3.6)
• switch to a different serial library (e.g. https://github.com/tiagocoutinho/serialio)

As the alternatives sound like they might introduce even bigger problems, I'm still in favour of merging this "cleaner solution" - at least for now.
