This causes a segfault. It happens whenever an object state larger
than 4095 byte is persisted. Then, incorrectly a try to rollover to
a new state file is tried, which will lead to a division by zero
as the necessary variables for this operation are not set because we
are NOT in circular mode.
This problem can happen wherever state files are written. It has been
experienced with imfile and queue files.
Many thanks to github user mostolog for his help in reproducing the
issue, which was very important to finally nail down this long-standing
bug.

Function computeBaseUrl may modify its serverParam parameter, but
this may contain the constant string "localhost". Depending on the
platform, this can lead to a segfault.
Noticed while working on compiler warnings, not seen in practice.

happens when gethostname() returns empty string. This will cause
the createon of the localhostname prop_t to fail, which in turn
leads to a NULL pointer dereference when emitting local messages.
As we emit a startup message by default, this had usually lead
to a segfault on startup.
Thanks to Erik Potter and github user mostolog for their help
in analyzing this problem.

This is only triggered if we do not get memory to do proper escaping,
so this code is unlikely to be executed. However, we think that
forwards slash is a better susbstitute for backslash than is the
single quote char.
commit 27af112637b47fd80c9ffb80565e61e049b88774 tried to fix
json encoding, but introduced an invalid predicate check that
lead to no encoding at all.

When previous signing failed, the newly created ksisig file is empty.
This has been fixed now. However if a logfile previously existed, the signature
verification process with fail because signatures for the loglines before
are missing. This problem needs to be evaluated in another issue.

We should provide a vehicle to set environment variables via the
config file. This is most importantly for things like HTTP_PROXY.
Currently, to do this system startup files need to be modified,
which is cumbersome and different from platform to platform.
