Currently the initscript is very complex. This makes it hard to read
and hard to add support for new init systems, such as systemd.
Create a wrapper called ctdbd_wrapper to be installed alongside ctdbd.
This is called by the initscript to start and stop ctdbd. It does the
ctdbd option construct and waits until ctdbd is properly initialised
before it exits.

* New directory nfs-rpc-checks.d/ replaces hardcoded rules in 60.nfs
* Installation and packaging additions to handle nfs-rpc-checks.d/
* Unit test updates, including deleting 1 test that sanity checked
test infrastructure
* Test infrastructure changes to use nfs-rpc-checks.d/
Note that this removes support for $CTDB_NFS_SKIP_KNFSD_ALIVE_CHECK in
60.nfs. To get the equivalent behaviour, edit 20.nfsd.check and
remove/comment all lines.

In RHEL 6+, rpc.statd runs as "rpcuser" instead of root as on RHEL 5. This
prevents CTDB tool commands talking to daemon since "rpcuser" cannot access
CTDB socket.

We've seen this function report "Unknown family, 0" and then CTDB
disappeared without a trace. If we can reproduce it then this might
help us to debug it.
The idea is that you do something like the following in /etc/sysconfig/ctdb:
export CTDB_EXTERNAL_TRACE="/etc/ctdb/config/gcore_trace.sh"
When we hit this error than we call out to gcore to get a core file so
we can do forensics. This might block CTDB for a few seconds.

winbind and samba can be separately managed. This makes the service
starting and stopping code way too complicated, and even adds a small
amount of complexity to the monitoring code. The sensible option is
to split this eventscript in two.
There are two potentially backward incompatible changes here:
* Functionality has been removed that allowed 50.samba to manage
winbind when CTDB_MANAGES_WINBIND was unset but the smb.conf
"security" parameter was set to "ADS" or "DOMAIN".
Maintaining this functionality would have required moving the
testparm-related code to the functions file, deciding where the
cache file should go, and then calling it from both 49.winbind and
50.samba. This feature wasn't of great value and asking
administrators to set an extra variable in exchange for code
simplicity seems like a reasonable deal.
* External code will need to be changed if it calls 50.samba directly
with winbind-related expectations. This is fairly obvious!

Break this debug and datacollection out into an external script to make it easier to modify what data we need to collect.
For now we only collect a pstree so we can see what part of the script we hung in.

We don't strictly need gawk (i.e. could probably use nawk), but that
seems to provide /bin/awk on RHEL.
PreReq seems old-school. We don't have an scriptlets, so nothing
needs to be installed before CTDB.

This will be the new long term stable branch for ctdb
Main new features are
read-only records: performance/scaling improvement for concurrent access to the same record from multiple nodes.
fetch-lock-collapse: performance/scaling improvement for concurrent write access to the same record from multiple nodes.
(This used to be ctdb commit 05e75dea9eaa0decc2909e0c2cf1715c81374200)
* Tue Nov 8 2011 : Version 1.12
- Add new tunable : AllowClientDBAttach that can be used to stop
client db access during maintenance operations
- Updated logging for interfaces that are missing or dont exist but are
configured to be used.
- Add timeout argument to ctdb_cmdline_client
- PDMA support
- Initial support for 'readonly' delegations for ctdb databases
This will when finished greatly improve performance for contended hot
records that are used for just read-access.
- New 'ctdb cattdb' command
- Massive updates to tests and eventscripts
- LCP2 ip allocation algorithm
- Record Fetch collapse. Collapse multiple fetch-lock requests from cients
to a single network fetch and defer other concurrent requests until the
initial fetch completes, and then service the deferred calls locally.
This will greatly improve performance for contended hot records
where clients request write-locks.

The init script does now check for the availability of tdbdump
and "tdbtool check" and issues warnings if they are not available.
This can remove a dependency loop with building samba RPMs.

so that the dependencies are right
or else the dependencies all end up in the devel package and not the main
ctdb package

This unifies our RPM version handling, based on tags.
1) Tags are of form ctdb-<version>.
2) The first <version> starts with .1.
3) Devel versions end with .0.<patchnum>.<checksum>.devel to reliably
identify them.
This means that devel versions will correctly supersede releases and earlier
devels, but new releases will correctly supersede older devel RPMs.
Making a new release is as simple as creating a new git tag.
