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).
Also: introduced explicit printer.Mode type (in
sync w/ parser.Mode, scanner.Mode, etc.)
Runs all tests. Applied gofmt to src, misc w/o changes.

(*Writer, error) if they take a compression level, and *Writer otherwise.
Rename gzip's Compressor and Decompressor to Writer and Reader, similar to
flate and zlib.
Clarify commentary when writing gzip metadata that is not representable
as Latin-1, and fix io.EOF comment bug.
Also refactor gzip_test to be more straightforward.
Fixes#2839.

This is for filling a column with "fail", like I just did for
Windows, when the builder would get stuck running that
build. (We have safeguards against the tests getting stuck
but this was the bootstrap build getting stuck.)
I usually use -cmd=/bin/false, but this avoids the Mercurial
checkouts, which means it runs instantly instead of requiring
~1 minute per "fail".

The comment on IsOneOf regarding Latin-1 was an implementation detail:
when the function is called internally, that condition is true. It used to matter,
but now the comment is a dreg. The function works fine if the character is
Latin-1, so we just delete the comment.
Fixes#2966.
