codeparser: accept a name for better messages

- If a name is passed to the parser, prepend the messages with "while
  parsing <name>:". This gives a bit more context.
- Tweak the warning messages slightly (they had to be altered anyway to
  inject the variable being parsed).

Before:
  DEBUG: Warning: in call to 'bb.data.getVar': argument ''%s' % var' is \
         not a literal

After:
  DEBUG: while parsing emit_pkgdata, in call of bb.data.getVar, argument \
         ''%s' % var' is not a string literal
