a02f84472a bc: BC_STATUS_VEC_ITEM_EXISTS is not a real error code, its message was never used
It was only used to indicate rusult of bc_map_insert() - did we insert, or
did we find that this key is already in the map?

c1c2470f84 bc: handle BIN_FILE and LEX_BAD_CHAR errors at the site of detection
The most informative message can be generated at the location
where error is detected. The "error codes" are stupid:
print error meesage immediately, then just return "there was an error"
indicator.

All error codes will be converted. For now, converting these two.

For now, this and following changes will degrade error messages
quality. For example, file name and line number printouts may be lost.
This will be re-added later.

This change anlso fixes handling of invalid stdin input:
this used to cause interactive bc to exit:

....
>>> ς
bc: illegal character 0xcf
bc: illegal character 0x82
>>> _

71e1fc6b37 bc: only check for ^C in bc_program_exec() main loop
Checking it in individual operations such as SQRT is not necessary
since they usually do not take very long to complete. We repeatedly return
to main loop.

TODO: re-add more fine-grained ^C checks - but only with examples where it is
actually needed. E.g. I suspect simplest ops like addition or compare won't need it.
