88e7faf860 Bug 11078: Add locking to rebuild_zebra
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.

190a7f404a installer: created skel directory
skel directory is for the installer only; contains
a directory structure and dummy READMEs used for
setting up the Zebra runtime and data directories.

Moved non-config files from etc/zebradb/* to
appropriate places under skel.
