3acc85caa8 buffering: use unbuffered silent mode for liblvm
Disable private buffering when using liblvm.
When private stdin/stdout buffering is not used always use silent
mode.

438e0050df config: add silent mode
Accept -q as the short form of --quiet.
Suppress non-essential standard output if -q is given twice.
Treat log/silent in lvm.conf as equivalent to -qq.
Review all log_print messages and change some to
log_print_unless_silent.

When silent, the following commands still produce output:
dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay,
pvs, version, vgcfgrestore -l, vgdisplay, vgs.
[Needs checking.]

Non-essential messages are shifted from log level 4 to log level 5
for syslog and lvm2_log_fn purposes.

c54998209d Update lvdisplay to show more info about thin LVs
Reformat name and path how the LV is represented with lvm1 compatible option,
to switch to the old way - which had number of  problem - i.e. many links
do not exist - since for private devices we are not creating them.
Add more info about thin pools and volumes.

cbedb99e4c Fix some compile warnings on RHEL5
- returned char not needed to be explicitly const
- warn if pipe() fails in clvmd (more fixes here needed for error paths...)
- assign (and ignore) read() output in drain buffer

a2552d4f59 Switch status from 32-bit to 64-bit
The physical_volume, volume_group, logical_volume and lv_segment
structures' 'status' member is now uint64_t.

The alignment of these structures was also audited to remove holes.  The
movement of some members in 'volume_group' and 'lv_segment' eliminates
holes.  The 'physical_volume' structure still has one 4-byte hole after
'pe_size'; the other structures no longer have any holes.  Each
structures' size has not changed.

61c146fb97 Add fflush for the case the log is redirected to the buffered file.
Without this patch it have not been obvious, why the application
waits on the stdin as the prompt might be still buffered in memory.

673ecf73cf Treat input units of both 's' and 'S' as 512-byte sectors. (2.02.49)
's' and 'S' are special suffixes representing sectors and are always 512 bytes,
regardless of whether you're using powers of 1000 or 1024.

95eaa68309 Add global/si_unit_consistency to enable cleaned-up use of units in output.

68fac97a07 Add vg_is_resizeable() and cleanup references.
Clean up VG_RESIZEABLE flag by creating vg_is_resizeable().
Update comment - we no longer have ALLOW_RESIZEABLE.
Also use vg_is_exported() in one place missed by earlier patch.
Should be no functional change.

905240f91d Use vg_is_exported(vg) macro everywhere.
This patch is all just cleanup and no other patch depends on it.

Update a few copyrights and remove unnecessary whitespace.
Should be no functional change.

3d425215a8 Continue to make --units and --size consistent (in code and man pages):
Update units_to_bytes() to support (S)ectors: 500 bytes.
- 500 byte (S)ectors is of questionable value but it adds to consistency
  if a user happens to use --units S.  This seems better than an error.

Updated test/t-covercmd.sh to test --units [hS]

Document the units that can be displayed via --units uniformly.
- (p)etabytes and (e)xabytes were missing in pvs, vgs and lvs man pages.

Made lvreduce man page "... in units of megabytes." consistent (with the
lvextend and lvresize man pages).

afd9ba98c1 Merge lv_is_displayable and lv_is_visible.
Displayable and visible is the same thing.

volumes_count(vg) is now vg_visible_lvs() and always
returns number of LVs from user perspective.
