Subject: [RFC 0/2] kconfig: Add fzf fuzzy search for config options

Hi,

These two patches are introducing a way to use fzf with the kernel
config options.

Using 'make fzfconfig' opens a list of all config options and their
state in the currently used configuration file. A preview is provided
for the currently selected config option in the list, showing the
original Kconfig snippet. Using Enter opens make menuconfig for the
selected option.

I reused the existing helpnewconfig command as it contains all the
information necessary and extended it to display all options using
helpallconfig. Using a wrapper script, that does simple parsing, the
view is transformed into a line based representation that is usable by
fzf.

I used this helper for some time now and it seems to work quite good for
me, though there may be cornercases for symbols etc. where it doesn't
work. I chose to use helpnewconfig/helpallconfig as it seems to be just
a small modification on the existing codebase to achieve fzf support.

Best
Markus
