bce585286d Remove global array kPolyBlockNames from Tesseract library 
It is only used in unittest/layout_test.cc after moving a test from
baseapi_test.cc to that file, so it can be made local.

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.
