selftests: watchdog: Fix ioctl SET* error paths to take oneshot exit path
When ioctls for WDIOC_SETOPTIONS (WDIOS_DISABLECARD or WDIOS_ENABLECARD),
WDIOC_SETTIMEOUT, and WDIOC_SETPRETIMEOUT fail, the error path continues
to handler watchdog timer until user terminates it. When ioctl returns
error, it might not be safe to let the watchdog tick. The error could be
due an unsupported ioctl command or some other error.
Fix it to handle error paths as oneshot to stop the watchdog ticks and
exit right away.

selftests: watchdog: get boot reason via WDIOC_GETBOOTSTATUS

Th
selftests: watchdog: get boot reason via WDIOC_GETBOOTSTATUS
Some watchdog drivers implement WDIOF_CARDRESET feature. As example,
see commit b6ef36d2c1e3 ("watchdog: qcom: Report reboot reason").
This option allows reporting to userspace the cause of the last boot
(POR/watchdog reset), being helpful in e.g. automated test-cases.
Add support for WDIOC_GETBOOTSTATUS in the test code, to be able to:
- check if watchdog drivers properly implement WDIOF_CARDRESET.
- check the last boot status, if WDIOF_CARDRESET is implemented.
Make the `-b, --bootstatus` option one-shot. That means, skip the
keepalive mechanism if `-b` is provided on the command line, as we
are only interested in the boot status information.
Tested on Rcar-H3 Salvator-X board:
********************** Cold boot finished
salvator-x:/home/root# ./watchdog-test -h
Usage: ./watchdog-test [options]
-b, --bootstatus Get last boot status (Watchdog/POR)
-d, --disable Turn off the watchdog timer
-e, --enable Turn on the watchdog timer
-h, --help Print the help message
-p, --pingrate=P Set ping rate to P seconds (default 1)
-t, --timeout=T Set timeout to T seconds
Parameters are parsed left-to-right in real-time.
Example: ./watchdog-test -d -t 10 -p 5 -e
salvator-x:/home/root#
salvator-x:/home/root# ./watchdog-test -b
Last boot is caused by: Power-On-Reset.
salvator-x:/home/root#
salvator-x:/home/root# ./watchdog-test -d -t 1 -p 2 -e
Watchdog card disabled.
Watchdog timeout set to 1 seconds.
Watchdog ping rate set to 2 seconds.
Watchdog card enabled.
Watchdog Ticking Away!
********************** Reboot due to watchdog trigger finished
salvator-x:/home/root# ./watchdog-test -b
Last boot is caused by: Watchdog.
salvator-x:/home/root#
salvator-x:/home/root# reboot
********************** Reboot due to user action finished
salvator-x:/home/root# ./watchdog-test -b
Last boot is caused by: Power-On-Reset.
salvator-x:/home/root#

commit f15d7114bbdd ("Documentation/watchdog: add timeout and ping rate
control to watchdog-test.c") used both atoi() and strtoul() for string
to integer conversion. As usage of atoi() is discouraged in newer code,
replace it with strtoul() for consistency.

selftests: watchdog: use getopt_long()
Switch from manual argv[] parsing to getopt_long() argument processing.
This creates more readable code and allows easier feature addition.
This also fixes some segmentation faults introduced by
commit 1dbdcc810928 ("selftests: watchdog: accept multiple params on
command line"), when options -t or -p are not given the required value:
./watchdog-test -p 1 -t
./watchdog-test -t 1 -p
No changes are intended in the way watchdog-test interacts with the
kernel. The only noticible changes, tightly related to the addition
of getopt (and done for easier maintenance), are:
- help message has been reworked and migrated to a dedicated function.
- all short/long options and the help message are sorted alphabetically.
- all case statements inside the getopt loop are sorted alphabetically.
Fixes: 1dbdcc810928 ("selftests: watchdog: accept multiple params on command line")
