Make the two functions that debug.c needs a subsystem of their own. The

dd4c019d9f debug: Fix debug_parse_params
The additional check this patch removes potentially drops some debuglevel
class settings. While not documented, it is possible to add a debug class
like for example "tdb:10" multiple times with multiple values. Later
settings overwrite earlier ones, but only if the overall number of
settings does not exceed the total number of available debug classes.

This patch changes our behaviour, but I can't imagine a situation where
someone relies on this check.

util_str has:

'/' is 0x2f, so there's no point in calling strrchr_m and thus pulling

c2094e3131 debug: Do not constantly rename logs when max log size = 0
In Samba4, the max log size parameter is not yet connected, so maxlog is 0

This means that we would, on receipt of a -HUP, have all child
processes attempt a rename.

Now we have the -HUP mean we reopen the logs unconditionally, and then
we see if the log is too large (samba3 mode) or simply proceed assuming
that someone else has renamed the logs for us.

b07d504ca4 change low FDs are handled in Samba
We now only close fds 0, 1, 2 when we are a forked daemon, and take
care not to close a file descriptor that we might need for foreground
stdin monitoring.

This should fix stdout logging in the lsa and epmapper deamons (ie in
make test).

ffb846ba7c lib/util/debug: with log level = 10 we should be more verbose
log level = 10 already impacts performance, so we can turn on
more details and print the pid, [e][u|g]id and class information.

So it implies "debug pid = yes", "debug uid = yes" and "debug class = yes".

This generates a lot more useful log files.

5f5ca913b7 lib/util: new merged debug system
This is the s3 debug system, with a number of changes to tidy it up
for common use.  The debug class system is simplified by the removal of the
ISSET table, the system no longer attempts to cope with assignment of
DEBUGLEVEL, and the full class table is always available (rather than
just DEBUGLEVEL_CLASS[DBCG_ALL]) from startup.  It is also no longer
confusingly described as a hack, but as the initial table.
