BugFixes to Berkeley DB 2.x and Features for slapd

[Kurt Spanier <zrnsk01@zdv.uni-tuebingen.de>]

Hi Folks,

I have fixed a bug in Sleepycat's Berkeley DB 2.x db_open() code, that
caused sporadic failure of slapd opening its database files, when run
with thread mode switched on. Platform was linux, kernel 2.0.35, with
kernel threads supplied through pthreads_1.60.4. The reason was simply 
a non-initialized variable. During search of the bug I have also added
db_appinit() at the first call to ldbm_open(), which will cause errors
within the DB library beeing syslog'ed in future times.

Furtheron, I have added a new command line parameter to slapd, '-l', which
will provide for a user-defined selection of syslog's LOG_LOCAL user on
platforms that support different LOCAL users. (-lLOCAL0 ... -lLOCAL7.) The
former build-in LOG_LOCAL4 remains the default, when no -l parameter is
given.

Last, but not least, the names of slapd's pid and args files will now be
computed on the binaries' name, rather than beeing fixed to 'slapd.pid'/
'slapd.args'. That may be used to have multiple slapd servers on one host
with different names. Each one will have its own set of pid/args files.
BTW, $RUNDIR)/var will now be created during make install, so that pid and
args files can be created during server start-up.
