Extracts kernel parameter values from /proc/cmdline. Handles bare and quoted parameters.
See kernel.org's docs on kernel parameters for
more information. While the docs mention using double-quotes to protect values
with spaces, we also recognize single-quotes and certain escape sequences to
support things like quoted="\"value\"".
Check out tests/*.txt to see examples of what we can extract.
