en: Fix several Microsoft-specific terms

Noticed build failure on NixOS when built package with 'make -j16':

    build flags: -j16 -l16 SHELL=bash
    Makefile:2844: warning: ignoring prerequisites on suffix rule definition
    make  all-am
    make[1]: Entering directory '/build/espeak-ng'
    Makefile:2844: warning: ignoring prerequisites on suffix rule definition
    touch dictsource/az_extra
    ...
    touch dictsource/yue_extra
    cd dictsource && ESPEAK_DATA_PATH=/build/espeak-ng LD_LIBRARY_PATH=../src: ../src/espeak-ng --compile=yue && cd ..
    bash: line 1: ../src/espeak-ng: No such file or directory
    make[1]: *** [Makefile:3546: espeak-ng-data/yue_dict] Error 127
    make[1]: Leaving directory '/build/espeak-ng'
    make: *** [Makefile:831: all] Error 2

The fix is to add dependency on 'espeak-ng' similar to other rules.

Fix pronunciation of given name Shaoni

This specifies that the es* mbrola voices are rather for Spanish
spanish.

The standard codename for United Kingdom for locales is UK.

- We want to use br* voices in priority for Brazilian Portugues, but not
  for general Portuguese.
- We want to use ca* and Belgian voices for Canadian and Belgian French,
  but rather not for general French.

It currently erroneously sets the fr5 voice.

Otherwise espeak_SetVoiceByName returns EE_OK even if the mbrola voice
file could not be loaded and thus setting the voice actually failed.

All other mbrola voices follow the "language-mbrola-number" name format.

This reverts commit 02783150cd.

This reverts commit aa765c7680.

Avoid converting input data to Float32Array

This will make it easier to set a default voice other than
English. This is important for cases when a language will fall back to
the default voice.

Some references to L('e', 'n') still need to be changed.

Found by parsing the results from this bash script:
for define in $(grep define *.h |  awk'{print $2}');
do if ! grep -q $define *.c
then
        echo "$define not found";
fi
done

This is unnecessary since the string is already null terminated in the
V_LANGUAGE switch case. sscanf creates a null terminated string in
language_name, which is then copied to voice_language by strcpy (keeping
the \0).

he: Add ךְ and ךָ

It's probably unnecessary code and could be removed. However, it would
break tests. This is a temporary solution.

The solution is to do it once in VoiceReset() and then if the "formant"
keyword changes voice->width.

Language option "stressOpt" already handles separate flags instead of a
single integer. There's no reason to have two ways of setting the same
option.

This is to make sure "stressopt" language option works. Current tests
would fail if it didn't.

language option "numbers" could be changed to use the same function, but
it needs tests.

ReadNumbers8) parses an unknown number of numbers from language files.
Used mostly for setting flags.
Used mostly for setting flags.

It is called multiple times in LoadVoice().

SetSpeed is needed when "speed" keyword changes voice->speed_percent.
