Test and generalize font configuration parser

Add a basic unit test for the Android font configuration parser.
Add a check for the new LMP file format; on detection, switch to a new
(as-yet unwritten) parser.

+    Fallback Fonts
+
+    This file specifies the fonts, and the priority order, that will be searched for any
+    glyphs not handled by the default fonts specified in /system/etc/system_fonts.xml.
+    Each entry consists of a family tag and a list of files (file names) which support that
+    family. The fonts for each family are listed in the order of the styles that they
+    handle (the order is: regular, bold, italic, and bold-italic). The order in which the
+    families are listed in this file represents the order in which these fallback fonts
+    will be searched for glyphs that are not supported by the default system fonts (which are
+    found in /system/etc/system_fonts.xml).
+
+    Note that there is not nameset for fallback fonts, unlike the fonts specified in
+    system_fonts.xml. The ability to support specific names in fallback fonts may be supported
+    in the future. For now, the lack of files entries here is an indicator to the system that
+    these are fallback fonts, instead of default named system fonts.
+
+    There is another optional file in /vendor/etc/fallback_fonts.xml. That file can be used to
+    provide references to other font families that should be used in addition to the default
+    fallback fonts. That file can also specify the order in which the fallback fonts should be
+    searched, to ensure that a vendor-provided font will be used before another fallback font
+    which happens to handle the same glyph.
