It will likely not fail to duplicate empty string, but
just keep the test of result of this function consistent.
Also on error path restore extent_size if in some
case someone would still use that variable.
Put common printf() case into a function and use
the string with text format as direct arg to make
the compile time validation of args easier and
code shorter.
Switch log_error() to log_warn(), since 'return 0'
doesn't cause any failure here.
Revert 4777eb6872 which put
target_present check into init_snapshot_merge(). However
this function is also used when parsing metadata. So we would
get this present test performed even when target is not really
needed. So move this target_present test directly into lvconvert.
The error buffer will stack error messages which is fine. However,
once you retrieve the error messages it doesn't make sense to keep
appending for each additional error message when running in the
context of a library call.
This patch clears and resets the buffer after the user retrieves
the error message.

Add a PV create which takes a paramters object that
has get/set method to configure PV creation.
Current get/set operations include:
- size
- pvmetadatacopies
- pvmetadatasize
- data_alignment
- data_alignment_offset
- zero

Replace the code with the refactored vgreduce_single instead
of calling its own implementation.

Moving the core functionality of vgreduce single into
lib/metadata/vg.c so that the command line and lvm2app library
can call the same core functionality. New function is
vgreduce_single.

All labellers always use the "private" (void *) field as the fmt pointer. Making
this fact explicit in the type of the labeller simplifies the label reporting
code which needs to extract the format. Moreover, it removes a number of
error-prone casts from the code.
Fix buggy usage of "" (empty string) as a numerical string
value used for sorting.
On intel 64b platform this was typically resolve
as 0xffffff0000000000 - which is already 'close' to
UINT64_MAX which is used for _minusone64.
On other platforms it might have been giving
different numbers depends on aligment of strings.
Use proper &_minusone64 for sorting value when the reported
value is NUM.
Note: each numerical value needs to be thought about if it needs
default value &_zero64 or &_minusone64 since for cases, were
value of zero is valid, sorting should not be mixing entries
together.
Add wrapper function for dm_report_field_set_value() which returns void
and return 1, so the code could be shorter.
Add wrapper function for percent display _field_set_percent().
This patch fixes mostly cluster behavior but also updates
non-cluster reaction where calls like 'lvchange -aln'
lead to incorrect errors for some segment types.
Fix the implicit activation rules where some segment types could
be activated only in exclusive mode in cluster.
lvm2 command was not preserver 'local' property and incorrectly
converted local activations in to plain exclusive, so the local
activation could have activate volumes exclusively, but remotely.
