* Remove gui_splash() * Rename gui_syncsplash() to splashf() and remove its voice capabilities. * Rename the internal splash() to splash_internal() and introduce an externally visible splash() that handles simple splashing without printf functionality e.g. splash(HZ, ID2P(LANG_FOO)); or splash(HZ, "foo"); if a LANG_* id is passed it will be voiced. * Adjust all places that called gui_syncsplash() to use the correct variant from above. * Export both new functions to plugins and adjust places calling rb->splash() to use the correct variant so that we now have naming consistency between the core and plugins. * Fix one latent bug that would cause my sim to crash with the above changes and correct P2STR and P2ID macros, thanks to pondlife. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18282 a1c6a512-1295-4272-9138-f99709370657
