[lm-sensors] [PATCH v2 1/7] sensord: Remove commandline interface.

[Andre Prendel <andre.prendel@gmx.de>]

Remove the hidden commandline interface of sensord.

Sensord can be invoked as an console application. Therefor a link
named sensors pointing to sensord is needed. That is very
intransparent and IMO useless. Printing sensor values to console is
done by the sensors tool.

Changes in v2:

Remove references to isDaemon.
Rename daemonShortOptions to shortOptions and daemonLongOptions to
longOptions.
Remove commandline flags doScan and doSet. They are needless without
the CLI.
Cleanup main().

Jean, there is some more useless stuff after the removal of the CLI
(e.g. the DO_SET action in doChip). I would prefer first to get this
series applied and remove the remaining stuff in further patches. Is
this OK for you?
