#791 add output hooks for wavegen

I've added some hooks to wavegen, which can be used to output aligned speech. This information can be used by prosody transplantation tools similar to MBROLIGN. There is also a function to set a constant f0 in Hz, which may be used by some prosody transplantation tools. If none of the functions is called, the behaviour of espeak-ng is unchanged.

By valdisvi:

Thanks! This approach seems more general to do integration with other tools than #749.

#795 Various code cleanups

Various code cleanups: change globals to function arguments, combine functions and remove unused code.

Most changesa re with the voice output (klatt.c, wavegen.c etc). There might not be enough test cases to detect if an error has been made here.

388be80da77e: code cleanup: pass voice_t wvoice as a parameter instead of using a global

SetSynth_Klatt() was using wvoice in two ways:
1) global wvoice was used directly
2) global wvoice was also passed in Wavegen_Klatt() as an argument "v"

Now the code only uses the function argument wvoice

Contributes to #68.

c0ff3696b950: code cleanup: change global int current_phoneme table to static

It's only used in SpeakNextClause() and related to SelectPhonemeTable().

Another solution void be to keep SelectPhonemeTable() as a void function
and do a current_phoneme_table = voice->phoneme_tab_ix after the call to
SelectPhonemeTable().

By valdisvi:

I cannot it reproduce on my computer and that change should not affect translation of text to phonemes. Have you made clean compilation e.g. make clean; make -B for your project?

[espeak-ng:master] New Comment on Issue #793 There needs to be a way to explicitly set stress only via rules to support unstressed languages and other non-European languages.
By michael-conrad:

As stress is relative, for sound it is the same. Only difference is that phonetic output is longer/more cluttered.

Which really doesn't help with setting an explicit stress via rules alone and not having the espeak-ng library "do things behind the language maintainers back".

And vowel length can change have a dramatic change of meanings of words in some languages:

• hị²go²wah²ta: You are seeing it. (inanimate / non-alive)
• hi²go²wah²ta: You are seeing him or her. (animate / alive)

Cherokee, for instance, has a specific long/short vowel cadence requirement, where long vowels are generally held twice as long as short vowels. That is the only pronunciation difference between long and short vowels and as such is significant.
