filemerge: rename _formatconflictmarker() since it formats a label

`_formatconflictmarker()`'s name made me think that it would create
something like `<<<<<<<` and maybe some more stuff after it, but it's
actually just the label that comes after on the same line. So let's
rename it to `_formatlabel()`. That's better aligned with the
variables the result is assigned it.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
