This patch fixed lvm2 compilation running on x32 arch.
(Using 64bit x86 cpu features but running on 32b address space,
so consuming less mem in VM).
On x32 arch 'time_t' is 64bit while 'long' is 32bit.

narrowed down on addressing the escaping of hyphens
in the dynamic creation of manuals whilst avoiding
them in creating help texts. This lead to a sequence
of slipping through hyphens adrressed by additional
patches in aforementioned commit series.
On the other hand, postprocessing dynamically man-generator
created and statically provided manuals catches all hyphens
in need of escaping.
Changes:
- revert the above commits whilst keeping man-generator
streamlining and the detection of any '\' when generating
help texts in order to avoid escapes to slip in
- Dynamically escape hyphens in manaual pages using sed(1)
in the respective Makefile targets
- remove any manually added escaping on hyphens from any
static manual sources or headers
raid1 doesn't allow to set all images to writemostly because at
least one image is required to receive any written data immediately.
The dm-raid target will detect such invalid request and
fail it iwith a kernel error message.
Reject such request in uspace displaying a respective error message.
The recent command definitions commit took the command
name from argv[0] without applying basename to the value,
so a pathname, e.g. /usr/sbin, would cause lvm to not
recognize the command name.
This commit supersedes reverted 1e4462dbfb
to avoid changes to liblvm and the libdm API completely.
The libdevmapper interface compares existing table line retrieved from
the kernel to new table line created to decide if it can suppress a reload.
Any difference between input and output of the table line is taken to be a
change thus causing a table reload.
The dm-raid target started to misorder the raid parameters (e.g. 'raid10_copies')
starting with dm-raid target version 1.9.0 up to (excluding) 1.11.0. This causes
runtime failures (limited to raid10 as of tests) and needs to be reversed to allow
e.g. old lvm2 uspace to run properly.
Check for the aforementioned version range in libdm and adjust creation of the table line
to the respective (mis)ordered sequence inside and correct order outside the range
(as described for the raid target in the kernels Documentation/device-mapper/dm-raid.txt).
This reverts commit 1e4462dbfb
in favour of an enhanced solution avoiding changes in liblvm
completetly by checking the target versions in libdm and emitting
the respective parameter lines.
Fixes command defs related to creating a new thin pool and
then a new thin lv in the new pool.
1. lvcreate --size --virtualsize --thinpool
Needs a cmd def, it was missing.
The def is unique by the three required
options: size, virtualsize and thinpool.
2. lvcreate --size --virtualsize --thinpool VG
Needs a cmd def, it was missing.
The def is unique by the three required
options: size, virtualsize and thinpool,
and one required positional arg: VG.
3. lvcreate --thin --virtualsize --size LV_new|VG
This existing def should not accept an optional
--type thin, which if used makes it indistinct
from another def.
4. lvcreate --size --virtualsize VG
This existing def should not accept an optional
--type thin or --thin, which if used makes it
indistinct from other defs (e.g. 3)
This reverts commit 642d682d8d.
Using the thinpool option with this cmd def makes it
indistinct from other cmd defs where thinpool is a
required option.

(The general rule is that a command is accepted if it is unambiguous.
The combination -L -V --thinpool uniquely identifies the operation.)
Udev events can come in like a flood when something changes. It really
doesn't do us any good to refresh the state of the service numerous times
when 1 would suffice. We had something like this before, but it was
removed when we added the refresh thread. However, we have since learned
that we need to sequence events in the correct order and block dbus
operations if we believe the state has been affected, thus udev events are
being processed on the main work queue. This change limits spurious
work items from getting to the queue.
If we always disable the sending of notify dbus events then in the case
where all the users are lvm dbus users we will be in udev handling mode
until at least 1 external lvm command occurs. Instead we will not disable
notify dbus until after we get at least 1 external event. This makes the
service get into the correct mode of operation faster.
lvconvert should not leak 'error' device.
(This patch is not fix the problem, just makes it more easily visible
instead of more confusing 'clvmd' trace).
Starting with dm-raid target version 1.9.0 shrinking of mapped devices is supported.
Check for support being present in lvresize and lvreduce.

Since we want to test different cache policies with profiles mq&smq
raise version to 1.8.
TODO: maybe split in more tests so older targets can test here as well.
N.B.: passthrough is also not supported with version 1.3
Quering non-thin-pool segment for discard property may lead
to intenal error if the segment had set 'out-of-range' value,
so only thin-pool is allowed, for other it returns NULL.
If SubLVs to be removed still exist after an image removing
conversion (i.e. "lvconvert --yes --force --stripes N "
with N < total stripes) any request to convert to a different
striped/raid* level has to be rejected until after those freed
SubLVs got removed by running the aforementioned lvconvert again.
Add tests to check conversion to striped/raid* gets rejected.
Enhance a test comment.
