  Add replaceable parameters in configuration files

Substitutable parameters can be specified. The format for defining a parameter is:
$PARAMETER=VALUE
where there must be no space before the '=' and only whitespace may preceed to '$'.
Empty values are allowed.

Parameter names can be made up of any combination of A-Za-z0-9 and _, but cannot start
with a digit.

After a parameter is defined, any occurrence of $PARAMETER followed by
whitespace, or any occurrence of ${PARAMETER} (which need not be followed by
whitespace) will be replaced by VALUE.

Replacement is recursive, so that if a parameter value itself includes a
replaceable parameter, then after the first substitution, the parameter
in the value will then be replaced; the substitution is done at replacement
time and not at definition time, so for example:

$ADDRESS_BASE=10.2.${ADDRESS_BASE_SUB}
$ADDRESS_BASE_SUB=0
    ${ADDRESS_BASE}.100/32
$ADDRESS_BASE_SUB=10
    ${ADDRESS_BASE}.100/32

will produce:
    10.2.0.100/32
    10.2.10.100/32

Note in the above examples the use of both ADDRESS_BASE and ADDRESS_BASE_SUB
required braces ({}) since the parameters were not followed by whitespace
(after the first substitution which produced 10.2.${ADDRESS_BASE_SUB}.100/32
the parameter is still not followed by whitespace).

If a parameter is not defined, it will not be replaced at all, so for
example ${UNDEF_PARAMETER} will remain in the configuration if it is
undefined; this means that existing configuration that contains a '$'
character (for example in a script definition) will not be changed so
long as no new parameter definitions are added to the configuration.

Parameter substitution works in conjunction with conditional configuration.
For example:
@main $PRIORITY=240
@backup $PRIORITY=200
...
vrrp_instance VI_0 {
    priority $PRIORITY
}

will produce:
...
vrrp_instance VI_0 }
    priority 240
}
if the config_id is main.

$IF_MAIN=@main
$IF_MAIN priority 240

will produce
 priority 240
if the config_id is main and nothing if the config_id is not main, although
why anyone would want to use this rather than simply
@main priority 240
is not known.
