- add translators from errno and GetLastError to LibError
- clarified return values of callbacks (they must return
INFO_CB_CONTINUE to continue)
- this exposed a few bugs in error handling chains (returning incorrect
values); also reduced say-nothing instances of return -1.
- move CHECK_ERR etc. macros to lib_error
