feat: install the SolidSyslog error handler

[DavidCozens]

Install the handler before any other call into SolidSyslog.

SolidSyslog_SetErrorHandler(OnSyslogError, NULL);

Nothing in the library fails loudly. A _Create that cannot succeed substitutes a Null object and
reports it rather than returning NULL, so a logger that has silently stopped looks exactly like
one with nothing to say. The handler is what tells the two apart, which is why it goes in before
the first _Create and not after something looks wrong. It reports many misconfiguration errors,
and can save significant time while integrating.

This is not only an integration aid. The handler is the seam into the device's own error and health
reporting, and it stays valuable at run time: later stages raise an edge-triggered warning when the
collector becomes unreachable and a notice when delivery recovers. Route it wherever the device
already routes faults — here, the same console as everything else, so a fault lands in the run
report next to the rest of what the device did.

The handler names the four lifecycle categories a misconfigured integration raises and prints the
rest numerically. A device reacting to a fault would switch on the category rather than the text.

When you need it. Every device, and first. It is the only thing standing between a
misconfigured logger and a silent one.

The build gains one source file and its include directory. Nothing about how SolidSyslog enters
the build changes.
