This is a similar change to b60d2452c3.
In this case, it is when tr->dictionary_name is passed as the name
parameter in LoadDictionary.

This happens in the SetTranslator2 function when loading the
dictionary for the second language translator object.

compiledict.c sets dict_name to dictionary_name if dict_name is
not set, and passes that to LoadDictionary. LoadDictionary then
copies the passed in name to dictionary_name.

This causes -fsanitize=address to fail with overlapping memory
addresses passed to strncpy (copying the string to itself). As
such, don't copy the name in this case.

synthesize.h now contains the definitions STRESS_IS_... that should be used with code related to syllable stress.

Note that isBreak and other defines were renumbered so that stress definitions could have values 0-6.

Possible TODOs:
1. Unify with terms used with phonemes, i.e. keywords like isDiminished in compiledata.c and stress_type in phsource/phonemes
2. Add functionality and documentation about STRESS_IS_PRIORITY and STRESS_IS_EMPHASIZED

Stress flag S_2_TO_HEAVY is currently only used by finnish.

Current behaviour skips adding secondary stress if the following syllable is heavy. The behaviour should be to skip adding secondary stress if the rest of the word (excluding last syllable) contains a heavy syllable.

This reverts commit 119c200e00.

This replaces uses of:

	memcpy(dst, src, strlen(src))

with:

	strcpy(dst, src)

This fixes issues with reading past the end of the copied buffer
(e.g. when processing word-based replacements for emoji characters)
by ensuring that the destination buffer is null terminated.

This was identified by the clang static analyser. The letter
variable is set in the various match_type switch cases, so
does not need to be initialised in the start of the while loop.

This was identified by the clang static analyser.

Clang static analysis reports a 'Dereference of null pointer'
error when accessing wtab->flags. This is properly guarded
against when setting the wflags variable, so use that variable
instead.

Clang static analysis reports this as several 'Result of operation
is garbage or undefined' errors, when `ending` has not been set
due to no matching endings.

This is related to ebfa320956169e3419234b72fee51bd596867661, but
when reading the hash chain entry length, not writing it.

If char is signed, then before this change the length would be
negative, causing problems loading the dictionary.

This fixes the clang warning:

    comparison of unsigned expression < 0 is always false
    [-Wtautological-compare]

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.
