e84cb24def Move source files which are used for training only to src/training 
They are moved from src/classify and src/lstm to src/training.

This reduces the size of the Tesseract library.

beec85e023 Remove UNICHARSET::load_from_inmemory_file and related code 
The method was only used in unittest where it can be replaced by
UNICHARSET::load_from_file which also simplifies the code.

This allows removing the class InMemoryFilePointer and fixes a TODO.

028fff6edd classify: Use fixed size bit vector 
The vector was already limited to MAX_NUM_PROTOS (512) entries or 64 bytes
in the old code. Now it uses that size right from the start which avoids
reallocating it later when entries are added.

The old code which reallocated the vector to expand it was buggy because
the realloc function can return a different pointer, but the code still
used the original pointer to reset the new bits.

Function ExpandBitVector is now unused and therefore removed.
