Merge tag 'de5e36b4ad69c4acfdd728b2ca3e0e472d91afd1'

ucd-tools 11.0.0.1

- fix a buffer overflow in ucd_tolower leading to failure when
compiling with address sanitizer
- force the use of C++ compiler for espeak-ng
- adding a malloc to have a null-terminated string in the fuzz target
- setting (but not overwriting) ESPEAK_DATA_PATH environment
variable inside the fuzz target

With the previous calculation, it was possible for the buffer to be
a byte or two too small to hold all of the data.

The only way (in Dec. 2019) to get espeak_ListVoices to actually list
all the voices, including variants and mbrola voices used to be to pass
a non-null voice selector with a null language pointer.  This still
seems to be supported in SetVoiceScores, which still checks for a null
language (see the check right at the top), however new code has been added
for a pseudo voice "all" lower down which seems to do the same thing but
crashes with null.  This change allows "old" code to continue working.

93d3c67df accidentally changes number handling for finnish.

D_FRACTION2 seems to match finnish number standards. It causes the
decimals to be read as numbers instead of individual digits: 12,12 is
read "twelve point twelve" instead of "twelve point one two".

It is undocumented so it might cause regressions as well.

Useful because capitals are not used in Mkhedruli script.

Uses the new lowercaseSentence setting.

When set in a language file, a period followed by a lower case letter is
detected as end of sentence. Normal behavior is to require a capital
letter.

I forgot to add fa: to previous commit message 4967418.

Pronounce dengler and binghamton the same way with and without a capital
letter.

Closes #895.

All sound file information goes to soundicon_tab. The contents of the files are not
loaded to memory before they are needed for synthesis.

This removes N_SOUNDICON_SLOTS that divided soundicon_tab into two
parts for unknown reasons.

TODO: LoadConfig() is currently undocumented. The logic should be
moved to LoadVoice() and documented.

Soundicons are used for external audio with SSML <audio> tag and for
replacing punctuation names with sound files in LoadConfig().

Currently there's a bug wih soundicon slots: if both LoadConfig and
<audio> are used, the punctuation reserves all slots and no sound from
<audio> is played.
