delegating the task to the user applications.
For now, I am calling sensors_get_ignored() in
sensors_get_all_features(), because this is the least intrusive way.
This is in no way optimal though, it would be better to not add
ignored features to the feature list in the first place. However,
doing so would require that the configuration file is read before
sysfs is scanned for features, which isn't currently the case. So
this improvement is left for later.
Note that this patch adds a small cost in terms of performance. This
is because we now honor ignore statements on all features (main ones
and subfeatures) while in practice "sensors" was only checking for
main features. It would be trivial to stop checking for subfeatures,
but it seems to me that supporting ignore on subfeatures is a good
move, as the user may actually want to ignore a specific subfeature.
Individual alarms come to mind. This will also be handy to debug the
generic print code in "sensors".

immediately follow their main feature. This makes it possible to simplify
sensors_get_all_features() quite a bit. We no longer need to maintain
separate pointers for the last main feature and the last subfeature,
we can simply walk the list linearly.
Note that I am still not entirely happy with this API. It was obviously
designed for debugging purposes (sensors -u) and without performance
concernes nor interface cleanliness in mind. I believe that we want to
tag main features and subfeatures as such, and let the application ask
specifically for the list of main features, and for each feature, for
its list of subfeatures (i.e. two functions instead of one.)

* We no longer support any single type, so no need to handle this case.
* We can start looking for "_" at offset 3 rather than the beginning
of the string (the shortest valid prefix is "in0", 3 characters.)

adjust it to fit our needs better:
* Call sensors_feature_get_type() before allocating memory for the
feature name. The allocation will be reverted for all sysfs files
which are not valid libsensors attributes, and there can be a lot
of these. So this saves a few memory allocations. But this means
that we want to pass a simple string to sensors_feature_get_type()
rather than a struct sensors_feature_data. This also means that
sensors_feature_get_type() gets the raw attribute name ("_input"
not stripped.)
* Get the channel number from sensors_feature_get_type() too. We
get it for free from sscanf(), so it's more efficient to return it
than to parse it again in sensors_read_dynamic_chip().

first called during the library initialization to generate the feature
tables. Then it is called again by sensors itself. This is because we
do not store the result the first time. I propose that we add a type
field to struct sensors_feature_data, where libsensors would store
the result of sensors_feature_get_type(). That way, the application
can get the information without calling sensors_feature_get_type()
again.
This change has the following benefits:
* Obviously, a small speed-up.
* sensors_feature_get_type() can be removed from the public interface.
This means that we can turn it into something that fits the
libsensors needs better, allowing for more optimizations (see next
patches.)
Note: the patch looks bigger that it really is, because I had to move
definitions around in sensors.h.

to display them as unknown chips.

if we discard them later, their presence in the list can prevent the
"no sensors found" event from triggering. It also causes the script to
suggest loading i2c bus drivers which are not needed for hardware
monitoring.

MAKEDEV to create them.
