Rewrite Fontconfig NixOS module Details: * The option `fonts.enableFontConfig` has (finally) been renamed `fonts.fontconfig.enable`. * Configurations are loaded in this order: first the Fontconfig-upstream configuration is loaded, then the NixOS-specific font directories are set, the system-wide default configuration is loaded, and finally the user configuration is loaded (if enabled). * The NixOS options `fonts.fontconfig.defaultFonts.monospace`, `fonts.fontconfig.defaultFonts.sansSerif` and `fonts.fontconfig.defaultFonts.serif` are added to allow setting the default system-wide font used for these generic faces. The defaults are the appropriate faces from the DejaVu collection because of their comprehensive Unicode coverage, clean rendering, and excellent legibility. * The NixOS option `fonts.fontconfig.antialias` can be used to disable antialiasing (it is enabled by default). * The options `fonts.fontconfig.subpixel.rgba` and `fonts.fontconfig.subpixel.lcdfilter` control the system-wide default settings for subpixel order and LCD filtering algorithm, respectively. * `fonts.fontconfig.hinting.enable` can be used to disable TrueType font hinting (it is enabled by default). `fonts.fontconfig.hinting.autohint` controls the FreeType autohinter. `fonts.fontconfig.hinting.style` controls the hint style; it is "full" by default. * User configurations can be disabled system-wide by setting `fonts.fontconfig.includeUserConf = false`. They are enabled by default so users can set Fontconfig options in the desktop environment of their choice.
