Presumably it is only developers that are interested in signals, and
terms like SEGV or ABRT are more precise than their textual
descriptions like "Segmentation violation" or "Aborted".
Poco::Channel is reference counted, but the initial refcount is 1, so we
need to release channel in order to have it deleted when Poco::Logger
releases it.
Calls to Poco::Logger::shutdown() are still missing though (from
forkit/kit/wsd).

Much better than assuming that errno would be relevant at all
Log::error() calls (or alternatively, having to remember to append a
false parameter to the Log::error() call, which had not been done a
single time anyway.)
Call log::syserror() right after a system call has returned an
error. Don't call it otherwise.
Admin no longer needs a pipe as it's notified
from WSD. It is now a singleton with improved
locking.
The tracking of documents and views still needs
improvement and corrections.

Don't embed newlines in "lines" written to the log. When logging stuff
read from or written to the fifos, translate newlines to " / " for
clarity.
(If we would want complete, exact verbose logging, we should be really
pedantic and log all non-printable bytes in hex anyway, etc, so
displaying newlines as space-separated slashes should be OK. It isn't
as if there would be totally arbitary data passed through the fifos
anyway.)
It is desirable to have colored logs when running loolwsd
in a terminal, but not redirecting its output to a file.
Outputting to a terminal is now detected and colored logs
are automatically enabled.
To force colored logs in files as well, define
LOOL_LOGCOLOR in the environ. The output color codes
can then be processed using, f.e., `less -r`.

Further changes/refactoring to make it possible:
* Add broker pid to Admin class
* Move getMemoryUsage for process to Util
* Change variable name to accurately reflect *active* items
_nViews -> _nActiveViews, etc.

Much simpler.
Also, don't duplicate the code informing that LD_BIND_NOW or
LOK_VIEW_CALLBACK are not set. Not that I understand why we need to
inform about that? If the "normal" thing should be that they are set,
why don't make it so by default then?
That is probably what was the intent. As originally written, in case
the function encountered partial writers, and had to do several
write() calls, only the number of bytes written by the last one was
returned.
Luckily the actual return value of writeFIFO() is not used
anywhere. It is just tested for being negative.
Still there is the problem that if at first one or several write()
calls succeed but don't write the whole buffer, and then a write()
fails, the caller has no way to know that the buffer has been
partially written. But that is hopefully highly theoretical and there
is no sane way to handle such a situation anyway.
The getChildStatus() and getSignalStatus() functions returned the
latter, still the returned values were compared against
Poco::Util::Application::EXIT_OK. (Sure, both Poco's
Application::EXIT_SUCCESS and stdlib.h's EXIT_OK are zero, but that
doesn't mean one should mix them up.)
Also add two comments pondering the meaning of the code.
Broker cache clean up is now done only during searching
as there we loop over processes and request status
from each child.
Internal helpers simplified and termination is done
in a single removeChild helper.

Error can supress printing errno and warning can
be asked to print it by setting a bool argument.
Formatting has been improved for readability.

This commit add 2 methods to encode a buffer to PNG: the "old"
method which encodes the whole buffer to a PNG, and a new method
to encode a part of a buffer (sub image) to PNG. The first method
is only added for convenience.
