cbe6fb38ec lib/tfork: Don't overwrite 'ret' in cleanup phase
The cleanup phase of tfork_create() saves errno prior to calling
functions that might modify it, with the intention of restoring it
afterwards. However, the value of 'ret' is accidentally overwritten. It
will always be equal to 0, and hence errno will not be restored.

Fix this by introducing a new variable, ret2, for calling functions in
the cleanup phase.

4e18e92399 util: add stable sort functions
Sometimes (e.g. in lzxpress Huffman encoding, and in some of our
tests: c.f. https://lists.samba.org/archive/samba-technical/2018-March/126010.html)
we want a stable sort algorithm (meaning one that retains the previous
order of items that compare equal).

The GNU libc qsort() is *usually* stable, in that it first tries to
use a mergesort but reverts to quicksort if the necessary allocations
fail. That has led Samba developers to unthinkingly assume qsort() is
stable which is not the case on many platforms, and might not always
be on GNU/Linuxes either.

This adds four functions. stable_sort() sorts an array, and requires
an auxiliary working array of the same size. stable_sort_talloc()
takes a talloc context so it ca create a working array and call
stable_sort(). stable_sort_r() takes an opaque context blob that gets
passed to the compare function, like qsort_r() and ldb_qsort(). And
stable_sort_talloc_r() rounds out the quadrant.

These are LGPL so that the can be used in ldb, which has problems with
unstable sort.

The tests are borrowed and extended from test_ldb_qsort.c.

When sorting non-trivial structs this is roughly as fast as GNU qsort,
but GNU qsort has optimisations for small items, using direct
assignments of rather than memcpy where the size allows the item to be
cast as some kind of int.

c7254de6fd util/debug: share classname table with tests
The executables generated from lib/util/tests/test_logging.c are used
by the samba.tests.logfiles tests to test logging with various
smb.confs that assign classes to various files at different levels
etc.

Previously test_logging.c had its own version of the table; now it
shares one with debug.c

We put the table in a sub-directory (lib/util/debug-classes/), because
adding local_include=True to the wscript_build stanza causes the
compiler confusion between <time.h> and lib/util/time.h.

Note: there are still two other lists of the class names, in
python/samba/tests/logfiles.py and
docs-xml/smbdotconf/logging/loglevel.xml.

1a6890a94d debug: add DBG_DEV()
This can be a useful macro when you are trying to track the behaviour
of one process out of the dozens that samba starts up, and when your
interest is in following it over time, not necessarily in a single
stack.

In DEVELOPER mode, if you call 'debug_developer_enable()' in the
process you're following, then any instances of DBG_DEV() will work
like DBG_ERR(), also adding ":DEV:12345:" where "12345" is the pid of
th current process.

Within debug.c itself, the macro always writes to stderr, because the
debug.c functions are not all reentrant.

When not in DEVELOPER MODE, the macro evaluates to nothing.

a8091bd0c5 util: Add new debug setting debug_no_stderr_redirect
CTDB doesn't want this redirection of stderr to the log file.  It
expects to be able to capture stderr of subprocesses and log them with
a header.  This redirection stops that from happening.

Unfortunately this has to be a negative option (i.e. "no" in the name)
so that the default of 0/false maintains existing behaviour.

Note that the default behaviour is sub-optimal because it causes raw
data (i.e. debug data without a header) to appear in the log.
