When building espeak-ng in a directory that has a long path, 80 bytes to
store it is quite short.

When the current locale doesn't match the current voice, grep would be
surprised by the produced output and believe that this is not text, for
instance with LC_ALL=ru_RU.CP1251 we get:

  TEST      tests/language-replace.test
[...]
testing mk
grep: (standard input): binary file matches
2d1
< Translate 'пејзаж'

But we can give -a to grep so it always considers its input as text.

Fixes #1152

fixes #700

this fixes #891

ref: https://github.com/espeak-ng/espeak-ng/issues/857#issuecomment-962500311

otherwise we get many errors

For the case when word is smaller than 4 characters, we should not look at
the 3rd or 4th character before checking the previous ones, otherwise
we'd at best read uninitialized data, at worse non-existing data.

Ref #853

Now that all errors are fixed.

Fix #1083 and improve some things in German

fname_temp is not always getting filled.

Otherwise we would miss errors produced on shutdown.

Otherwise they will go unnoticed.

Now that all memory errors are fixed.

Ref #220

Some rules test against character not being of a certain type. That may
match with the \0 end-of-text marker, and thus actually step over
it and let MatchRule continue with uninitialized data after it, leading
to potential random behavior.

This commits fixes it by making sure that we don't read past that \0.

This seems to be changing the pronunciation of "capitals" from k'apIt@Lz to
k'apIt,alz, I don't know why, I guess the rule for it was actually
bogus?

Now that it is fixed by

dab5457620 "Fix deleting FrameManagerImpl*"
261954b4bd "Fix deleting SpeechWaveGenerator"

let's be honest, using espeak-ng without these dictionaries is simply
unbearable... at least for Russian. so let's all get a little bit happy.

Now that all tsan errors are fixed.
