this is required so we can elegantly swap out an old config for a
new one in the future and remove lots of boilerplate from config
initialization code.
unfortunately this is a quite intrusive change as the config struct
was accessed in numerous places, but frankly it should have been
done via a pointer right from the start.
right now, we simply point to a static struct in main.c, so there
shouldn't be any noticeable changes in behaviour.
if daemon mode is used and neither logfile nor syslog options specified,
this is clearly a misconfiguration issue. don't try to be smart and work
around that, so less global state information is required.
also, this case is already checked for in main.c:334.
since the write syscall is used instead of stdio, accesses have been
safe already, but it's better to use a mutex anyway to prevent out-
of-order writes.
tinyproxy uses a curious mechanism to log those early messages
that result from parsing the config file before the logging mechanism
has been properly set up yet by finishing parsing of the config file:
those early messages are written into a memory buffer and then
are printed later on. this slipped my attention when making it possible
to log to stdout in ccbbb81a.
some users want to run tinyproxy on an as-needed basis in a terminal,
without setting it up permanently to run as a daemon/service.
in such use case, it is very annoying that tinyproxy didn't have
an option to log to stdout, so the user has to keep a second terminal
open to `tail -f` the log.
additionally, this precluded usage with runit service supervisor,
which runs all services in foreground and creates logfiles from the
service's stdout/stderr.
since logging to stdout doesn't make sense when daemonized, now if
no logfile is specified and daemon mode activated, a warning is
printed to stderr once, and nothing is logged.
the original idea was to fail with an error message, though some users
might actually want to run tinyproxy as daemon and no logging at all.
Now that there is always a log file set, we just check for
syslog being set to TRUE and in that case use syslog logging,
file logging otherwiese.

Now that we exit early when !logging_initialized, this
can actually not happen anymore anyways: When logging is
initialized, it was also properly configured.

This way the logging from the various child processes does not
get clobbered up. Formerly, the different write portions
(time stamp, message, newline) would get mixed from the
various child processes' log messages.
Michael
When this code is hit, availability of syslog has already
been checked (when reading the config file). So config.syslog == TRUE
only when HAVE_SYSLOG_H is defined.
So I remove the preprocessor checks which only clobber the logic
and make the code harder to read (IMHO).
Michael
This controls whether log_messages should write to the
log file / syslog or rather to the log_message_storage.
This will make the global processed_config_file variable
from main unneccessary in the next step.

The modified files were indented with GNU indent using the
following command:
indent -npro -kr -i8 -ts8 -sob -l80 -ss -cs -cp1 -bs -nlps -nprs -pcs \
-saf -sai -saw -sc -cdw -ce -nut -il0
No other changes of any sort were made.
The notices have been changed to a more GNU look. Documentation
comments have been separated from the copyright header. I've tried to
keep all copyright notices intact. Some author contact details have
been updated.
I re-indented the source code using indent with the following options:
indent -kr -bad -bap -nut -i8 -l80 -psl -sob -ss -ncs
There are now _no_ tabs in the source files, and all indentation is
eight spaces. Lines are 80 characters long, and the procedure type is
on it's own line. Read the indent manual for more information about
what each option means.
