This fixes lots of warnings related to ERRCODE like the following one:

The function did not correctly read Chinese unichars into the local
Class variable if the locale was set to de_DE.UTF-8 (or other
incompatible locales). That resulted in a wrong ClassId which was
used to write into the Cutoffs array without checking for valid bounds.
On macOS the result was a runtime error in baseapi_test (see GitHub
issue #1250):
[ RUN ] TesseractTest.InitConfigOnlyTest
baseapi_test(21845,0x1134c45c0) malloc: *** error for object 0x927f96c28005e0: pointer being freed was not allocated
baseapi_test(21845,0x1134c45c0) malloc: *** set a breakpoint in malloc_error_break to debug
Replacing sscanf by std::istringstream fixes that.
Add also an assertion to catch future out-of-bounds writes.

Skip the tests which need the legacy code.
Add also code to those tests to use the user's locale to test that, too.

The latest code passed all unittests with locale de_DE.UTF-8
and has fixed the locale issues which were reported on GitHub.
Therefore the assertions can be removed.
Any remaining locale issue will be fixed when it is identified.
To help finding such remaining isses, debug code now uses the
user's locale settings instead of the default "C" locale for all
executables which use TessBaseAPI.

That function writes float values which must always use '.' as the
decimal separator, no matter what the current locale setting is.

Void functions should not use @return. It causes compiler warnings
like this one:
