Here we convert the logical padding properties into their new resolved-at-
cascade-time implementations. This involves:
* converting -moz-padding-{start,end} into logical longhand properties
* adding padding-inline-{start,end} aliases for -moz-padding-{start,end}
* converting padding-{left,right} into longhand properties
* removing padding-{left,right}-value and
padding-{left,right}-{ltr,rtl}-source internal properties
The CSS parser and various tests are simplified a bit as a result.
We define a new flag CSS_PROPERTY_LOGICAL to be used for logical longhand
properties and a new CSS_PROP_LOGICAL macro in nsCSSPropList.h to
define them.
When using CSS_PROP to capture all properties, includers must now
explicitly indicate whether logical properties are included or not,
by defining CSS_PROP_LIST_EXCLUDE_LOGICAL (to exclude them),
CSS_PROP_LIST_INCLUDE_LOGICAL (to include them), or CSS_PROP_LOGICAL
(to capture them separately from other properties).

Ideally we'd make this property inaccessible to Web content style sheets, but
that seems hard since view-source and plain text documents seem to load in a
context that's very similar to Web content as far as the style system is
concerned. It doesn't matter much since it's quite safe and unlikely to be
discovered or used by anyone.
This adds entries for property aliases as though they are shorthands.
This fits with the CSS working group's recent resolution to describe
aliases as shorthands, recorded in
http://lists.w3.org/Archives/Public/www-style/2012Aug/0770.html .
The property_database.js entries themselves are copied from the
non-alias entries for the properties, with these changes:
(1) The property name is changed to the prefixed form
(2) The domProp entry is changed to the prefixed form
(3) Adding alias_for entries for each property.
(4) When type is CSS_TYPE_LONGHAND in the target of the alias, type for
the alias is CSS_TYPE_SHORTHAND_AND_LONGHAND and a subproperties
entry is added with the target of the alias.
There are also some indentation fixes to the copied entries in
property_database.js (made before they were copied, and thus affecting
the original as well).
