watchdog: pass USEC_INFINITY to watchdog_setup() to reuse the programmed timeout value
This patch changes the meaning of USEC_INFINITY value for the watchdog
module.
Previously passing this value was a NOP. It now has a special meaning: it
requests the watchdog module to read the programmed timeout value and reuse it
for pinging the device.
This is mostly useful when the watchdog is started by the firmware and there's
no way to reconfigure the timeout with a different value
afterwards. "RuntimeWatchdogSec=infinity" in system.conf can now be used rather
than putting an arbitrary value that PID1 will fail to set (even if it still
felt back to the programmed timeout).
Please note that "infinity" is not supposed to restore the default value of the
firmware. If the value is changed after booting then "infinity" would simply
reuse the current programmed value. IOW it's a NOP unless the watchdog was
previously closed and in that case it will be reopened and the last programmed
value reused.

recuse-dir: rework to use getdents64() instead of readdir()
Let's use the underlying Linux API directly, instead of
opendir()/readdir(). This makes it possible for us to do a single memory
allocation for all directory entries in common cases, instead of one for
each entry.

missing: add getdents64() syscall wrapper
glibc 2.30 (Aug 2019) added a wrapper for getdents64(). For older
versions let's define our own.
(This syscall exists since Linux 2.4, hence should be safe to use for
us)

localed: use PROJECT_FILE rather than __FILE__ for logging
All our log.h code uses PROJECT_FILE for this, let's hence use it here
too.

ethtool-util: let's use userspace types in userspace code
Using kernel types __u32 is fine for headers shared by the kernel, but
if we define something in userspace and only use it in userspace, in our
own .c files, let's stick to userspace fixed-length types.

We use __func__ almost everywhere, but there are some holdouts. Fix
that.

network: use official bswap_32() rather than inofficial __bswap_32()
The former is a macro for the latter, but let's use the official API
(the one that has an API).
