report: support printing full column names in report headings 
Reuse existing report/headings config setting to make it possible to
change the type of headings to display:
  0 - no headings
  1 - column name abbreviations (default and original functionality)
  2 - full column names (column names are equal to exact names that
      -o|--options also accepts to set report output)

Also, add '--headings none|abbrev|full|0|1|2' command line option
so we are able to select the heading type for each LVM reporting
command directly.

#
# Syntax
#
# A new command has a unique combination of:
# command name, required option args and required
# positional args.
#
# To define a new command, begin a single line with a
# command name, followed by required options/args,
# (e.g. --foo, or --foo val), followed by required
# positional args, (e.g. VG)
#
# After the single line of required elements are lines
# of optional elements:
# OO: <optional --option args>
# OP: <optional positional args>
#
# command_name required_opt_arg ... required_pos_arg ...
# OO: optional_opt_arg, ...
# OP: optional_pos_arg ...
#
# required_opt_arg/optional_opt_arg must begin with the
# long form option name, e.g. --foo. If the option name
# takes a value, then the type of value is specified,
# e.g. --foo String.
#
# Possible option names are listed in args.h
#
# Use --foo_long to specify that only the long form of
# --foo is accepted by the command. (This is uncommon.)
#
# Possible option arg types are shown in tools/vals.h,
# e.g. Bool, String, VG, SizeMB.
#
# --option args outside the list of types in vals.h are treated
# as literal (non-variable) strings or numbers.
#
# positional args can be multiple types separated by |, e.g. VG|LV|Tag
#
# If a positional arg is repeatable, it is followed by ..., e.g. VG|LV|Tag ...
#
# LV can have a suffix indicating the LV type, e.g. LV_linear, LV_thinpool.
# LV_raid represents any raidN. LV_type1_type2_type3 when the LV is
# limited to multiple specific types.
#
# Note that two commands whose required paramters differ only by
# the LV types they accept are ambiguous. That is, they cannot be
# distinguished by just looking at the command, but require reading
# the VG to find the LV type. So, command definitions that differ
# only in accepted LV types are not allowed. It would be best to
# distinguish them by using different option names.
# There are FIXME's below for some of these cases.
#
# VG, LV can have the suffix _new, indicating the named VG or LV
# does not yet exist.
#
# If Select is included in pos_arg, it means that the pos_arg
# may be empty if the --select option is used.
#
# --size and --extents are interchangable, but only --size is used
# in these definitions to keep them simpler. --extents is
# automatically included and recognized as an alternative to --size.
#
# lvcreate generally requires a VG arg in position 1 and does not
# require the --name option (when --name is omitted, a name is
# generated). But, all commands of that form have a variant which
# is not defined here, but which is automatically recognized as
# being equivalent. That variant allows the required VG arg to
# be omitted when --name VG/LV is specified, or when the
# LVM_VG_NAME env var is set and --name LV is specified.
# The lvcreate variants with --name and without a VG arg are
# automatically recognized as an alternative to the defined
# command forms requiring the VG and no --name.
# Also, --thinpool VG/LV or --cachepool VG/LV can be used in
# place of --name to provide the VG name instead of pos 1.
#
# Note that one the most difficult aspect of these definitions is
# the variants of --thin / --type thin / --type thin-pool,
# --cache / --type cache / --type cache-pool.
# There are no consistent rules to follow and the behaviors are
# unpredictable; each possible variation and combination needs
# to be tested individually to see what it means.
#
# Some options have multiple names, but only one form of the name
# is used in these definitions. Synonyms will be recognized when
# matching a command to a command definition.
#
# used in definitions below (equivalent but not used in definitions)
# mirrorlog core (not corelog)
# resizeable (resizable or allocation)
# allocatable (allocation)
# activate (available)
# rebuild (raidrebuild)
# syncaction (raidsyncaction)
# writemostly (raidwritemostly)
# minrecoveryrate (raidminrecoveryrate)
# maxrecoveryrate (raidmaxrecoveryrate)
# writebehind (raidwritebehind)
# virtualsize (virtualoriginsize)
# splitcache (split)
# vgmetadatacopies (metadatacopies)
# pvmetadatacopies (metadatacopies)
#
# "---" is like a comment line, used to separate text for readability
#
# ID: A unique string identifying the command. Two commands that do
# the same thing, but are alternate syntaxes can share the same ID,
# in which case the implementation would have to sort out which
# args to look at for the required parameters. Or, the two commands
# could use differnet IDs, in which case the implementation would
# know where to look for each parameter.
#
# DESC: A description of the command. The "DESC:" tags will be
# included in the text as indicators of new lines when printing
# the descriptions for help/man output.
#
# RULE: rules that a given command must follow, i.e. required (and)
# or invalid (not) combinations of options, LV types or LV properties.
#
# RULE: A and|not B
#
# Conditions in A are applied to a given command+LV.
# If the conditions in A are true, then the checks in B
# are applied. If the checks in B are true|false according
# to and|not, then the command fails|continues.
#
# When A is "all", the conditions in B are always applied.
#
# Conditions:
# . if any --option listed is set, the checks may apply
# . if any LV_type listed matches LV, the checks may apply
# . if all lv_is_prop listed matches LV, the checks may apply
# . if all of the above pass, then perform the checks
#
# Checks for "and":
# . if any --option listed is not set, then fail
# . if none of the LV_types matches the LV, then fail
# . if any of the lv_is_prop do not match the LV, then fail
#
# Checks for "not":
# . if any --option listed is set, then fail
# . if any of the LV_types matches the LV, then fail
# . if any of the lv_is_prop match the LV, then fail
#
# RULE: --option|LV_type|lv_is_prop|all ... and|not --option|LV_type|lv_is_prop ...
#
# RULE: --opt1 not --opt2
# RULE: --opt1 and --opt2

#
#
# AUTOTYPE: <segtype>
# The cmd def implies the type. Optionally using --type foo
# is not wrong, but it's redundant. If --type is specified
# it is not used in matching a user command to the cmd def,
# but once a user cmd is matched to the cmd def, a specified
# type is compared to the AUTOTYPE to ensure they match.
# We avoid including --type foo in the OO list because doing
# so often makes the cmd def redundant with another cmd def
# that has --type foo in its required_options. We want a user
# command to only match a single cmd def.
# Usually, a user command with --type foo will match a cmd def
# that includes --type foo in its required_options.
#
# For lvcreate cmd defs, each should either include --type foo
# in required_options, or it should include AUTOTYPE foo
# (and not include --type in OO).
#
# For efficiency, sets of options can be defined and reused
# in multiple command definitions.
#
# To define a common set of options:
# OO_NAME: --foo, --bar String
#
# To use this set of options, include it on the OO: line, e.g.
# OO: --example, OO_NAME
#
# which is expaneded to
# OO: --example, --foo, --bar String
#
# Including OO_NAME after a command name on the required line
# means that any one of the options is required and the rest
# are optional. The usage syntax for this case is printed as:
# command (--foo A, --bar B)
