This is not used by any of the espeak-ng voices and languages.
Additionally, this functionality would be superceded by support
for specifying the language used by different scripts in the
language argument on the command line.

Moved include/espeak/speak_lib.h to include/espeak-ng/speak_lib.h and
created a symlink from the original location.

Allow to decrease the score in the rule by adding

Fixed length stressed vowels in tr_language.c (see #80).

Improved phonemes, new statements for [a] and long close [o].

Added last improvements in italian dict source tested on april-may 2016.

The clang scan-build static analysis tool warns of a null pointer
dereference in WritePhMnemonic. This is only for phonSWITCH codes,
which is guarded against in the calls that pass NULL to plist, so
the null dereference should not trigger.

Always passing plist supresses this warning, and prevents any
future errors.

This commit has been reported to cause distortions in phoneme
pitches and speeds.

Also use size_t instead of int in some places
where it make sense

This removes the implementation of those functions from espeak-ng
and use the versions in libespeak-ng.

NOTE: This is needed to cross-compile to Windows.
