genprotimg: add host-key document verification support

Add host-key document verification support to genprotimg. This ensures
that a host-key document is genuine and provided by IBM. For this the
user must provide the IBM Z signing key, the intermediate CA
certificate (signed by the root CA used) so a chain of trust starting
from the host-key document and ending in the root CA can be
established.

By default, genprotimg tries to download all revocation lists needed
by looking up in the corresponding certificate on how CRL information
can be obtained (see https://tools.ietf.org/html/rfc5280#section-4.2.1.13
for details).

-
-Options:
--i, --info:
-	Displays detailed information about installed and available
-	CPU-measurement facilities and the related Linux support.
-
--c, --counter authorization_value
-	Displays counter information for the current System z hardware.
-	The authorization value provides information about the authorized
-	counter sets. The value must be specified in decimal format.
-
-	To display all supported counters, specify C<65535> (FFFF hex).
-
-	To display supported counters for a particular System z hardware,
-	use the --ctr-def option and specify the System z hardware type.
-
---hardware-type
-	Displays the System z hardware type.
-
---ctr-def ctr-definition
-	Displays detailed information about the specified counter definition.
-	Valid counter definitions start with C<cfvn-> or <csvn-> followed by
-	the counter first/second version number of the CPU-Measurement Counter
-	Facility.  To display counter information of model-specific counter
-	sets, specify the System z hardware type for I<ctr-definition>.
-
---ctr-set-names
-	Displays the mapping of counter set IDs to counter set names.
-	The counter set IDs are numbers that are used in counter definitions.
-
---ctr-set-ids
-	Displays the counter set IDs.  The counter set IDs are numbers that
-	match the authorization bits (see QUERY COUNTER INFORMATION).
-	The output format is a list. To get the ID for a particular counter
-	set, use an index number as follows:
-
-	0: Basic Counter Set
-	1: Problem-State Counter Set
-	2: Crypto-Activity Counter Set
-	3: Extended Counter Set
-	4: MT-diagnostic Counter Set
-	5: Coprocessor Group Counter Set
-
---ctr-sf
-	Displays the counter definitions for the sampling facility support.
-	These counter definitions are specific to Linux perf infrastructure.
-
---sfb-size
-	Displays the size of the sampling facility buffer (SFB). The minimum
-	and maximum numbers are measured in units of sample-data-blocks. A
-	sample-data-block uses about 4 kilobytes.

+.TH LSSTP 8 "Jul 2020" "s390-tools" "Linux Administrator's Manual"
+.SH NAME
+.B "lsstp "
+\- Show STP configuration information
+.SH SYNOPSIS
+.BI "lsstp "
+
+.SH DESCRIPTION
+.B lsstp
+displays information about the current Server Time Protocol (STP) configuration
+like coordinated time network (CTN) ID, timing state and leap seconds.
+.SH OUTPUT
+.TP
+.B STP online
+Indication of the online state
+.TP
+.B CTN ID
+The ID of the coordinated time network. If it can be decoded as EBCDIC it is shown as an EBCDIC string, otherwise a hexadecimal representation is shown.
+.TP
+.B CTN Type
+The type of timing network.
+.IP
+.B No CTN
+STP is not configured for attachment to a CTN.
+.IP
+.B STP-only
+STP is configured and attached to a CTN with only STP nodes.
+.IP
+.B Mixed
+STP is configured and attached to a CTN with both STP and external time reference (ETR) nodes.
+.TP
+.B Stratum
+The number of servers in the timing path between the local STP clock and the selected primary time server.
+.TP
+.B Timing mode
+.IP
+.B Local
+The Time-of-day (TOD) clock is stepped by the local hardware oscillator and is not steered by the STP facility.
+.IP
+.B ETR
+The TOD clock is synchronized with an attached 9037 Sysplex Timer.
+.IP
+.B STP
+The TOD clock is steered by the STP facility to maintain synchronization with a Coordinated Server Time (CST).
+.IP
+.B Uninitialized
+The TOD clock is not initialized. The STP facility is allowed to perform a step adjustment to the TOD clock for synchronization.
+.TP
+.B Timing state
+The synchronization state of the STP facility. Can be unsynchronized, synchronized or stopped.
+.TP
+.B DST offset
+The daylight savings time offset relative to UTC in minutes.
+.TP
+.B Timezone offset
+The offset of the local time relative to UTC in minutes.
+.TP
+.B Time offset
+The total time offset at the server. This field is only valid in mixed CTN configurations.
+.TP
+.B Active leap seconds
+The number of leap seconds that are currently in effect at the STP facility.
+.TP
+.B Leap second <insertion|deletion> at
+If a leap second insertion or deletion is scheduled in the STP facility, this field shows the day and time of the scheduled change.
+.SH OPTIONS
+.TP
+.BI "-v|--version"
+Print version number.
+.TP
+.BI "-h|--help"
+Print usage text.
