NeilBrown ba728be72f Convert 'quiet' to 'not verbose' in various places.
If we change some functions to accept 'verbose', where <0 means to be
quiet, in place of 'quiet', then we will be able to merge
'quiet' and 'verbose' together for simplicity.

NeilBrown 503975b9d5 Remove scattered checks for malloc success.
malloc should never fail, and if it does it is unlikely
that anything else useful can be done.  Best approach is to
abort and let some super-daemon restart.

So define xmalloc, xcalloc, xrealloc, xstrdup which don't
fail but just print a message and exit.  Then use those
removing all the tests for failure.

Also replace all "malloc;memset" sequences with 'xcalloc'.

Adam Kwolek 6e75048bc5 Add recovery blocked field to mdinfo
When container is assembled while reshape is active on one of its member
whole container can be required to be blocked from monitoring.
For such purpose field recovery blocked is added to mdinfo structure.

When metadata handler finds active reshape in container it should set
recovery_blocked field to disable whole container monitoring during
reshape.

For arrays that doesn't use containers, recovery_blocked field
has the same value as reshape_active field e.g. super0/1.
In fact,recovery is blocked during reshape for such arrays.
For ddf, metadata handler doesn't set reshape_active field,
so recovery_blocked is not set also.

NeilBrown 95eeceeb32 getinfo_super now clears the 'info' structure before filling it in.
Some code currently clears 'info' before calling getinfo_super,
some code doesn't.

To be consistent, change it so no caller ever clears 'info',
but ever getinfo_super function must clear it.

Note that ->raid_disk may be meaningful if that 'map' is passed
non-NULL.  In that case it is copied out before the structure
is zeroed.

Czarnowska, Anna c21e737ba1 set default chunk in validate_geometry
When chunk size is not set from command line we need to guess it
depending on metadata given on command line or found on listed devices.

Validate_geometry sets the default for it's metadata if chunk is not set.
For external metadata chunk is set only when creating in a container.
For imsm validate_geometry_imsm_orom is responsible for finding default
chunk depending on container metadata loaded. Container will already know
which controller it is attached to, and have this controllers orom
available.
do_default_chunk indicates that we need to find default chunk and
if validate_geometry fails for some metadata it tells us to reset chunk
that may have been set.

Current solution would set default chunk correctly for imsm only if
container device was given on command line. With the list of devices
chunk was always set to 512.

NeilBrown 1cc7f4feb9 Don't close fds in write_init_super
We previously closed all 'fds' associated with an array in
write_init_super .. sometimes, and sometimes at bad times.
This isn't neat and free_super is a better place to close them.

So make sure free_super always closes the fds that the metadata
manager kept hold of, and stop closing them in write_init_super.

Also add a few more calls to free_super to make sure they really do
get closed.
