This fixes the intonation in Latin American Spanish questions, removes
the phoneme replacement (T to s) because it is already included in
phonemes es_la. It also eliminates the line languaje es 6, because when
the voice is in the dialect of Spain and it automatically changes to the
dialect of Latin America, it does not return to the dialect of Spain.

Note: this doesn't fix actual problem for some of the older devices.
Unfortunately i don't have devices with os version below than android 7,
so am not able to test.

On e.g. iOS it may be very long.

Helps to make #1291

So we can ship data bundle and compile it AOT.

Helps to make #1291

Fixes for some code smells found with cppcheck static code analysis tool.

Strlen never retuns a negative value. Also combined if statements to
reduce complexity. This code currently has no tests.

Inner 'n_bytes >= 0' will always be true.

Inner 'p->stresslevel>=4' will always be true. Thus checking for
count_stressed is redundant.

Unify common parts of two implementations. Split into smaller functions.

Google is now a LLC not Inc.

This allows to cover
- another arch that x86, which is also very common
- an arch where char is unsigned
- a little-endian arch

This is running under qemu-user, so significantly slower and doesn't
support ptrace thus no address sanitizer etc. but at least the undefined
sanitizer works.

implemantations.

It is unclear why the two implementations differ.

we currently only support 22050 as samplerate so this code has no
effect. This should be readded to setSpeed() with and without Sonic if
multiple samplerates are supported in the future.

There are two SetSpeed(), one for Sonic and one without. The differences
are very small.

In SetSpeedMods(), sample rate is adjusted for Sonic only:
 speed.min_sample_len = (speed.min_sample_len * samplerate_native) / 22050;

Since samplerate_native is 22050 at the moment this line has no effect.

nvda happened to be speaking 3647 because strtoi was actually
overflowing. Better make sure to have proper ascii to number translation
before continuing.

Fixes #1385

Note: This code has no tests. Tests would pass even without a call to
this function.

Changing da_rules was accidentally included in the commit.
