13c3f53f55 allocation: misc fixes for percent/raid rounding
Several fixes for the recent changes that treat allocation percentages
as upper limits.
Improve messages to make it easier to see what is happening.
Fix some cases that failed with errors when they didn't need to.
Fix crashes when first_seg() returns NULL.
Remove a couple of log_errors that were actually debugging messages.

37b7c67079 thin: report thin device id
Support   lvs -o+thin_id  to report thin device id.
This device_id is connection between kernel and lvm2 user space thin

8e1f2e733e gcc: fix comparing floating point warning
Since we enabled some more gcc warnings - let's adapt for
it and check for double equals with DBL_EPSILON.

Current close_enough() is far from perfect
for more details see i.e. here:
http://randomascii.wordpress.com/2012/01/11/tricks-with-the-floating-point-format/
but fairly enough for lvm2 use-case.

386886f71c config: refer to config nodes using assigned IDs
For example, the old call and reference:

  find_config_tree_str(cmd, "devices/dir", DEFAULT_DEV_DIR)

...now becomes:

  find_config_tree_str(cmd, devices_dir_CFG)

So we're referring to the named configuration ID instead
of passing the configuration path and the default value
is taken from central config definition in config_settings.h
automatically.

3acc85caa8 buffering: use unbuffered silent mode for liblvm

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.

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.

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).
