7a96516819 Never scan suspended devices in clvmd.
For mirror repair (and similar tasks) it can happen that full
device rescan is issued from clvmd.

Because code can be in the middle of repair (calling suspend)
clvmd should never try to scan suspended devices
(otherwise it causes deadlock).

Also code must not change ignore_suspended_device flag when
doing refresh_filters (called from lvmcache scan code).

99a304bc17 Optionally abort on internal errors (and leverage this option in the
testsuite). (This is showing a problem in the pvmove test for me, so I expect
the tests to start failing -- this needs to be fixed separately though.)

cd501dd440 Move persistent filter dump to more appropriate place.
After context_refresh is cache empty, the cache flush
does nothing.

Call it after lvmcache full rescan if running from
log lived process.

e1ab01e3ad Refresh device filters before full device rescan in lvmcache.
The sysfs filter initialise hash of available devices using
scan of /sys/block. We need to refresh even this hash
when performing full scan otherwise the newly appeared
device could be rejected, because there is no entry
in sysfs filter.

This easily could happen when attaching new device
to cluster node. (Only force refresh of context
in clvmd -R works here now).

Unfortunately consequences of this are much worse,
missing device part on that node is replaced with missing segment
(even when no partial arg is selected) and this directly
lead to data corruption.

See https://bugzilla.redhat.com/show_bug.cgi?id=538515

Simply fix it by refreshing device filters in lvmcache
before performing the full device scan.

0296197999 Create global is_static() to eliminate from the library init function.
Very simple / crude method of removing 'is_static' from initialization.
Why should we require an application tell us whether it is linked
statically or dynamically to libLVM?  If the application is linked
statically, but libraries exist and dlopen() calls succeed, why
do we care if it's statically linked?

c5c13fe776 Remove struct arg * from struct cmd_context and create_toolcontext().
This allows us to remove one argument from create_toolcontext() and
moves it closer to a generic library init function.

In the arg_*() functions, we just use _the_args() directly.
For now we leave the first parameter to these
arg_*() functions (struct cmd_context *) because
of the number of files involved in removing the
parameter.

9a04baa27c Move initialization of cmd->fmt into init_formats().
init_formats() sets up the command formats, and currently sets cmd->fmt_backup
but does not set cmd->fmt to a default value.  This seems incorrect so we
set it to cmd->default_settings.fmt before returning.

The call we remove here may set cmd->fmt based on a command line setting.
But it is safe to remove this, because the only caller of init_lvm() that
cares about the cmdline override is the cmdline tools (clvmd does not care),
called from lvm2_main().  After lvm2_main() calls init_lvm(), it later calls
lvm_run_command().  In lvm_run_command(), we have a call to _apply_settings(),
which has the identical assignment of cmd->fmt that this patch removes.

a51b3f838d Remove backup_enable() calls after create_toolcontext() calls.
Identical argument to previous patch which removed archive_enable() calls.
We add a new parameter to backup_init() which sets the enable value based
on the cmd->default_settings.backup value.  This value was used to set
cmd->current_settings.backup, used in the removed backup_enable() call.

4fa2c7f8b6 Remove archive_enable() calls after create_toolcontext() calls.
_init_backup() calls archive_init(), which originally set 'enabled' to
a hardcoded '1' value.  This seems incorrect based on my read of other
areas of the code so here we add a 'enabled' paramter to archive_init().
We pass in cmd->default_settings.archive, which is obtained from the
config tree.  Later in create_toolcontext, cmd->current_settings is
set to cmd->default_settings.  The archive_enable() call we remove
here was using cmd->current_settings to set the 'archive' enable
value.  The final value of cmd->archive_params->enabled should thus
be equivalent to the original code.

058f3d3523 Move init_test() from _apply_settings into _init_logging().
This one we actually need to move.  _init_logging() is called from
    create_toolcontext(), which makes this call:
        /* Test mode */
        cmd->default_settings.test =
            find_config_tree_int(cmd, "global/test", 0);

But it does not call init_test().  So we need an init_test() somewhere.
The most logical place is to put it inside _init_logging(), since this
is where the config value is read and default_settings are set.  Placing
the init_test() call here matches what is done with other variables and
seems to make sense.
