[tbot] Release 0.7.1

[Harald Seiler]

Hello!

I just released version 0.7.1 of tbot.  The changes are as follows:

== Added ==
- `tbot.acquire_local()`: Quick access to a localhost machine.  When you do
  not select a lab, this is equivalent to `tbot.acquire_lab()`, but when your
  lab is remote, you can use this new function to easily get access to your
  localhost.
- `LocalLabHost.tbotdir`: tbot's current working directory on the localhost (either
  from where you ran `tbot` or the path given with `-C`).  In conjunction with
  the previous change, you can use this
for example to very easily copy files
  from your tbot-repo to your lab-host:

	from tbot.tc import shell

	with tbot.acquire_lab() as lh:  # The selected (possibly remote) lab-host
	    target_path = lh.workdir / "file.c"

	    with tbot.acquire_local() as lo:  # Always localhost
	        local_path = lo.tbotdir / "data" / "file.c"  # File in tbot-dir

	        shell.copy(local_path, target_path)  # Copy to lab

	    # Use file on lab-host
	    lh.exec0("gcc", target_path, "-o", lh.workdir / "file")

  Of course, this also works the other way around.

- `LinuxMachine.home`: Path to the current user's home.  Quick access to $HOME.
- `tbot.tc.kconfig`:  Testcases for modifying a kernel config file
- `login_delay`: Time to wait before logging in on the board.  This should
  allow working with boards that clobber the console a lot during boot.
  (Thanks to Lukasz for adding this!)

== Changed ==
- Unknown parameters are now ignored if running multiple testcases so
  you can specify parameters that are just relevant to a single one.
- `SSHMachine`s now use `NoneAuthenticator` by default.

== Fixed ==
- `selftest`s sometimes failing if dropbear does not start fast enough
- `SSHMachine`s using the local user's home dir instead of the one on the
  lab-host.
- Local channels now correctly end the session which fixes weird bugs like
  picocom not being able to reaquire the shell.  This makes the fix I posted a while
  ago obsolete.

I also added a rendered PDF version of the docs to the release:
