fdd612b824 generators: avoid contacting syslog with generators
The systemd generators are executed very early during the switch
from initramfs to system partition and the syslog is not yet fully
operational - it may cause blocking, if some debug logging is enabled
at the same time in /etc/lvm/lvm.conf log{} section.

To avoid timeouting and killing this generator - rather enhance lvm
code to suppress any syslog communication when LVM_SUPPRESS_SYSLOG
envvar is set.

Use of this envvar is needed since the parsing of i.e. cmdline options
that could eventually override lvm.conf setting happens in this case
way too late and number of lines could have been already streamed to
syslog.

904e1e3d26 Place the first PE at 1 MiB for all defaults
. When using default settings, this commit should change
  nothing.  The first PE continues to be placed at 1 MiB
  resulting in a metadata area size of 1020 KiB (for
  4K page sizes; slightly smaller for larger page sizes.)

. When default_data_alignment is disabled in lvm.conf,
  align pe_start at 1 MiB, based on a default metadata area
  size that adapts to the page size.  Previously, disabling
  this option would result in mda_size that was too small
  for common use, and produced a 64 KiB aligned pe_start.

. Customized pe_start and mda_size values continue to be
  set as before in lvm.conf and command line.

. Remove the configure option for setting default_data_alignment
  at build time.

. Improve alignment related option descriptions.

. Add section about alignment to pvcreate man page.

Previously, DEFAULT_PVMETADATASIZE was 255 sectors.
However, the fact that the config setting named
"default_data_alignment" has a default value of 1 (MiB)
meant that DEFAULT_PVMETADATASIZE was having no effect.

The metadata area size is the space between the start of
the metadata area (page size offset from the start of the
device) and the first PE (1 MiB by default due to
default_data_alignment 1.)  The result is a 1020 KiB metadata
area on machines with 4KiB page size (1024 KiB - 4 KiB),
and smaller on machines with larger page size.

If default_data_alignment was set to 0 (disabled), then
DEFAULT_PVMETADATASIZE 255 would take effect, and produce a
metadata area that was 188 KiB and pe_start of 192 KiB.
This was too small for common use.

This is fixed by making the default metadata area size a
computed value that matches the value produced by
default_data_alignment.

4b5d6de86b pvscan systemd service for event based activation
The pvscan systemd service for autoactivation was
mistakenly dropped along with the lvmetad related
services.

The activation generator program now looks at the new
lvm.conf setting "event_activation" (default 1) to
switch between event activation and direct activation.

Previously, the old use_lvmetad setting was used to
switch between event and direct activation.

c1cd18f21e Remove lvm1 and pool disk formats
There are likely more bits of code that can be removed,
e.g. lvm1/pool-specific bits of code that were identified
using FMT flags.

The vgconvert command can likely be reduced further.

The lvm1-specific config settings should probably have
some other fields set for proper deprecation.

f2ee0e7aca pvmove: require LV name in a shared VG
In a shared VG, only allow pvmove with a named LV,
so that only PE's used by the LV will be moved.

Previously, pvmove was mistakenly allowed on a full PV.
This won't work when LVs using that PV are active on
other hosts.

Table lines are separated by commas.
Devices are separated by semi-colons.
Flags is currently 'ro' or 'rw' (and might be extended in a
yet-to-be-defined way in future).
Any comma, semi-colon or backslash within a field is quoted by a
preceding backslash.

The format can later be supplied as input to dmsetup or even to the
booting kernel as an alternative way to set up devices.

f611b68f3c vgchange: separate change locktype and allow recovery
Add an independent command definition for "vgchange --locktype",
and split the implementation out of the set of common metadata
changes.  It is unlike normal metadata changes, and can only
be run by itself.  (Changing the lock type is similar in
principle to changing the VG name or the VG system ID; it
effects the ability of any host to see or access the VG.)

At some point this command lost the ability to forcibly change
the lock type of a shared VG to "none" (making it a local VG).
This can be necessary to repair shared VGs (e.g. recovery steps
that occur in vg_read are disabled for shared VGs because
they are not locked properly, or recovering sanlock locks
when the PV holding them is lost.)

"vgchange --locktype none --lockopt force VG" is used as the
method of forcing the shared VG to become local so that it
can be repaired.
