lszcrypt now evaluates and displays the 'status' in the

The 'STATUS' field was within the code used as 'online'
record because it showed the online state. But now it
displays some more info like 'deconfig' and maybe even
more in the future. So now the code also uses a 'status'
record for this info.

Slight rework of the lszcrypt code with:
- a queue or card in deconfigured mode is displayed
as 'deconfig' regardless which driver is bound to
the device.
- a queue or card in 'deconfig' mode does not show
any counters any more but displays a '-' instead.
- a queue not bound or bound to something else as
the 'default' zcrypt dd does not show any counters
but displays a '-' instead.

A compile with sparse (make C=1) shows a couple of warnings:
like:
chzcrypt.c:36:3: warning: symbol 'l' was not declared.
Should it be static?
lszcrypt.c: In function 'show_device':
lszcrypt.c:556:9: warning: 'card' may be used uninitialized
[-Wmaybe-uninitialized]
Fix those warnings.

lszcrypt now shows a card/queue which is in 'deconfigured' state as
'deconfig' in the STATE column (verbose and non verbose mode).
chzcrypt became two new options: --config-on and --config-off to
switch one or more card devices to 'configured' or 'deconfigured'
state.
Both applications are able to handle older kernels which do now
provide the config sysfs attribute required for this new feature.

With kernel 4.19 there comes an extension to the existing
AP bus which supports alternate zcrypt drivers. For details
about this see kernel patch "s390/zcrypt: AP bus support for
alternate driver(s)". So now lszcrypt displays the driver
name in verbose mode. As some of the information displayed
by lszcrypt was based on sysfs attributes, which are only
available when the default zcrypt driver is bound to the
device, this also needed some rework. If a sysfs attribute
is not available because of an alternate driver binding
(or no driver) a question mark is printed into the field.
Together with this a slight rework of the displayed information
has been done. The two columns for pending requests and pending
replies has been merged to one pending column and the column
sizes have been adjusted.

The sysfs files ap_control_domain_mask and ap_usage_domain_mask
may hold just a string "not supported" if there's no crypto
configuration available. However, lszcrypt always processed
the content of these files as hex number and so produced funny
output if there's no configuration data available.
