Log Message:
Update misc/py-anita to 1.42.  Changes from 1.41:

VM console input is no longer logged to stdout, to keep it from
appearing twice when echoed by the VM.

Fix VM console output appearing twice in interact mode (again).

Add support for gxemul as a new VMM and NetBSD/pmax as a new guest.
From Utkarsh Anand.

Increase the default test timeout to 24 hours, as the tests now
take much longer to run than before due to a combination of
the addition of new tests and qemu performance regressions.

Added target support for NetBSD/evbarm-earmv7hf, from Utkarsh Anand.
This installs from a pre-built image rather than using sysinst.

When installing from a file: URL or local path, avoid creating
unnecessary copies of the release files.  From Utkarsh Anand.

New command line option --tests for explicitly selecting the the Kyua
test framework instead of ATF, from Utkarsh Anand.
