benefits:
  Espeakedit now honors the specified USE_AUDIO flag.
  Remove duplication.

Build

Makes it easier to see where speak_SOURCES and libspeak_SOURCES differ.

Add --version command-line option.

Allow hexadecimal numbers for UTF-8 bytes in rules in *_rules files.

wave_pulse.cpp, ensure wave_close is not called again while waiting.

Improve error detection in *_list files.

Lang=hu, remove feature to unstress the second of two capitalized words at end of clause.

Fixed crash on re-initializing libespeak.

lang=hu, experimental, if the last two words of a clause (before punctuation) both have capital letters, then make the last word unstressed.  This is useful for people names, but may be wrong for other cases.

lang=en-us, distinguish phonemes [aI@] and [aI3] (compare "diet", "tired").

lang=de, fix automatic devoicing of word-final 'b', 'd', 'g'.

Conflicts:

Fixed bug where SSML voice change didn't remember an initially specified Klatt variant.

Removed some unused variables and redundant initializations.

Patch to fix a spike from Klatt function setzeroabc()

If setzeroabc is passed f == 0, rp->a will be set to 0 and when
the coefficients get inverted (a'=1/a, b'=b/a, c'=c/a) then a',
b' and c' get set to INF. This results in an audible sound spike
when these resonators get used.

Found when investigating an issue in klatt with example1.par when
using the cascade synthesis mode.

Conflicts:
	src/synthdata.cpp
	src/voices.cpp

Added runtime detection of pulseaudio, with fallback to portaudio if pulse is not running.  Use build option "AUDIO=runtime" in the makefile.

Phoneme programs. Added condition "isTranslationGiven" to test whether a phoneme has been specified explicitly for a word in *_list.

*_rules files.  Suffix rules are now considered only if there is a previous vowel in the word.

Fix: Brazilian Portuguese, set "pt-br" as the primary language code.

Fix problem where speed can get set to minimum after an SSML <mark> tag.
