The debugging code is done inconsistently, mainly to trace the
event and audio output logic. This makes it harder to understand
the code flow for logic that is not enabled by default.
As such the debugging code makes the code harder to maintain.
The libespeak files are supposed to be C code, so use C linkage
for all the functions defined in that code when they are being
referenced in the C++ code (i.e. espeakedit).
Changed -b option to include an option for 16 bit character input.
numbers.cpp: Added option for vigesimal number systems for tens+units.
Fixed problems with word-length indications in callback events.
-m option now ignores XML comments.
