Use bitmasks to define which inputs are available. Makes it easier to remove old assumptions of which are available. Inspired by e200 being unique in having FM Radio and Mic but no Line. Doesn't remove the assumption that Mic is available or that one of Mic and/or Line is available just to avoid excessive #ifdef'ing until needed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13448 a1c6a512-1295-4272-9138-f99709370657

Enable setting of global output samplerate on certain targets. Replaces the NATIVE_FREQUENCY constant with a configurable frequency. The user may select 48000Hz if the hardware supports it. The default is still 44100Hz and the minimum is 44100Hz. The setting is located in the playback settings, under "Frequency". "Frequency" was duplicated in english.lang for now to avoid having to fix every .lang file for the moment and throwing everything out of sync because of the new play_frequency feature in features.txt. The next cleanup should combine it with the one included for recording and generalize the ID label. If the hardware doesn't support 48000Hz, no setting will be available. On particular hardware where very high rates are practical and desireable, the upper bound can be extended by patching. The PCM mixer can be configured to play at the full hardware frequency range. The DSP core can configure to the hardware minimum up to the maximum playback setting (some buffers must be reserved according to the maximum rate). If only 44100Hz is supported or possible on a given target for playback, using the DSP and mixer at other samperates is possible if the hardware offers them.
