b1bf5f1738 Make clvmd-cman use a hash rather than an array for node updown info.
This will allow it to cope with very large nodeids such as those
generated by clusters using cman_tool join -X

e7f55bb4c0 Get clvmd to use libcman rather than cman ioctl calls. This makes
it forward-compatible with the new userland CMAN in cluster head.

To build it you will need the libcman header & library installed.

3329bbfdf3 make clvmd FDs close-on-exec, to avoid warnings when running lvm via popen.
clvmd-gulm unlocks VG & orphan locks at startup in case they are stale.
clvmd-gulm now unlocks VG & orphan locks if client dies.

6f4d25ec7f Fix clvmd startup bug introduced in cman/gulm amalgamation. bz#145729
Improve reporting of node-specific locking errors so you'll get
somthing a little more helpfiul than "host is down" - it will now tell
you /which/ host it thinks is down.

5c7fc7c4f7 You can now build clvmd with cman & gulm support in the same binary.
./configure --with-clvmd
wil do this by default. Or you can choose which you want with
./configure --with-clvmd=gulm    or
./configure --with-clvmd=cman

When clvmd with both included is run, it will automatically detect the cluster
manager in use.

badd6fb7ba Report detailed errors in cluster initialisation to syslog, and point the user
at syslog if clvmd fails to intialise.

b1098701ec Can now build a gulm version of clvmd instead of a cman one. use
./configure --with-clvmd=gulm

The default is still cman, and you can't have both - sorry.

8d81a737a4 Change some perror() calls to log_error() so they'll appear in
syslog when we're a daemon.

8ef0b7b9ef Keep client locks (VG locks usually) in their own hash table so
we can actually have more then one of them per client.
