the values for the host system (running the build), not
the target. pkg/ is not technically appropriate, but C objects
are there now tool (pkg/obj/) so this puts all the generated

If a printer is configured with the SourcePos mode
set, it will emit //-line comments as necessary to
ensure that the result - if reparsed - reflects the
original source position information.
This change required a bit of reworking of the
output section in printer.go. Specifically:
- Introduced new Config mode 'SourcePos'.
- Introduced new position 'out' which tracks the
position of the generated output if it were read
in again. If there is a discrepancy between out
and the current AST/source position, a //line
comment is emitted to correct for it.
- Lazy emission of indentation so that //line
comments can be placed correctly. As a result,
the trimmer will have to do less work.
- Merged writeItem into writeString.
- Merged writeByteN into writeByte.
- Use a []byte instead of a byte.Buffer both in the
printer and in the trimmer (eliminates dependency).
