In addition to ensuring that usb-moded gets restarted in case it gets stuck,
the process watchdog ping-pong allows scheduling of maintenance tasks at
times when system is going to be active anyway.

The systemd development packages have changed and there are build time
warnings like:

  sd_notify was moved to libsystemd. Do not use libsystemd-daemon.

Use libsystemd as instructed.

Remove -Wdeclaration-after-statement as first using -std=gnu99 to allow c99
features and then explicitly requesting warnings about using c99 features
makes little sense.

Remove -W option as it is just backwards compatibility alias for
-Wextra.

Remove -Wformat as it is implied by having -Wall present.

Forgot to add bug ref to commit, so 0.86.0+mer8 got rejected by ci-bot.

Make a dummy version bump and add bug ref to make ci-bot happy.

[ssu] Use ssusysinfo instead of SSU D-Bus interface. Fixes JB#36841

During bootup usb-moded needs device name / model information before
the system has reached a point where SSU daemon can be started. This
can cause systemd deadlocks and/or timeouts as usb-moded waits for SSU
daemon and the rest of the bootup is blocked until usb-moded reaches
ready state.

Use ssu-sysinfo C-library that can provide the device details required
by usb-moded without using any IPC mechanisms.

Make some ELF sections readonly with -z relro and -z relro now

Unless the code base is actively used with other than gcc compilers, use
of -pedantic just denies use of handy gcc extensions like use of "%m"
format parameter instead of non-thread-safe strerror().

Drop the '-pedantic' option and replace all strerror() calls with "%m".

Maintaining usb manufacturer and product name configurations for multiple
devices is cumbersome and time consuming. It also duplicates effort that
is needed for ssu configuration anyway.

When possible, override usb-moded manufacturer and product name
configuration by using data provided by ssu D-Bus service.

The feature is optional and needs to be enabled at usb-moded build
time via "--enable-mer-ssu" configure option.
