This patch adds locking to rebuild_zebra.pl to ensure that simultaneous
changes are prevented (as one is likely to overwrite the other).
Incremental updates in daemon mode will skipped if the lock is busy
and they will be picked up on the next pass. Non-daemon mode
invocations will also exit immediately if they cannot get the lock
unless the new flag -wait-for-lock is specified, in which case they
will wait until the get the lock and then proceed.
Supporting changes made to Makefile.PL and templates for the new
locking directory (paralleling the other zebra lock directories).
We stash the zebra_lockdir in koha-conf.xml so rebuild_zebra.pl
can find it.
To address earlier QA concerns we:
1. added code to check if flock is available and ignore locking if
it's missing (from M. de Rooy)
2. changed default for adhoc invocations to abort if they cannot
obtain the lock. Added option -wait-for-lock if the user prefers
to wait until the lock is free, and then continue processing.
3. added missing entry to t/db_dependent/zebra_config.pl
4. added a fallback locking directory of /tmp

Doug merged the original patch with the QA changes.
Just for the record, noting here that the original patch was tested
extensively too by Martin Renvoize.
I have added a followup for some exceptional cases.

If running Zebra, try to locate zebrasrv and zebraidx
so that koha-zebra-ctl.sh can point to a functioning
zebrasrv.

The daemon control scripts (koha-zebra-ctl.sh, koha-zebraqueue-ctl.sh,
and koha-pazpar2-ctl.sh) are now copied and installed in a
runnable fashion for a 'dev'-mode install. By default
they are installed in the bin subdirectory of the runtime
directory.
Also:
* the control scripts now work if the EUID is other
than root (as would be expected for a 'dev' or 'single'
install).
* Split the SCRIPT_DIR installation target into
SCRIPT_DIR (scripts to copy regardless of install mode)
and SCRIPT_NONDEV_DIR (scripts to copy to SCRIPT_DIR
unless the install mode is 'dev').

* adding zebra daemons for managing server and queue processes
* improvements to the README.debian file
* Fixes to Search.pm since last series of commits broke zebra-based
searching (again)
* moving some files to new misc/bin and misc/cronjobs
