Similar as done with SAPI / MSSP make the current implementation for executable
based TTS engines a base class and create derived classes for each supported
TTS. Removes the need for the implementation to know about the individual TTS
engines.
Add support for speaking directly (i.e. without going through a temporary wave
file, currently only used by espeak).

As with espeak, a string starting with - is wrongly interpreted as command line
option. Explicitly end options using -- to fix this.

When calling espeak via command line explicitly indicate the end of options.
Fixes the voice string "-inf" getting recognized as unrecognized command line
option, breaking speaking.

The configuration values for executable based TTS systems is stored in member
variables. Instead of reading them multiple times provide a function for that
and move searching the executable to the loading function.
Previously the executable was only searched in the path when opening the TTS
configuration. Having this in the loading function removes that unnecessary
step in case the TTS is in the path (and doesn't require additional
configuration).

Instead of simply assuming the wav file that is supposed to be created by the
TTS engine check if the file actually exists and return an error if not.

Move class-less functions in utils.cpp into a new Utils class and make the old
functions static. This prevents clashes with system C functions. Rename some
functions to avoid macro problems (check() is a macro on OS X). Split out the
RockboxInfo class into a separate file.
