Remove some unused functions, constants and variables

This fixes compiler warnings, for example: src/ccutil/strngs.cpp:36:11: warning: unused variable 'kMaxDoubleSize' [-Wunused-const-variable] src/viewer/svutil.cpp:320:13: warning: unused function 'TessFreeAddrInfo' [-Wunused-function] src/ccstruct/werd.cpp:32:19: warning: unused variable 'CANT_SCALE_EDGESTEPS' [-Wunused-const-variable] src/textord/bbgrid.cpp:103:10: warning: unused variable 'old_tright' [-Wunused-variable] Signed-off-by: Stefan Weil <[email protected]>
