Robert Findley 9e1d19b13e internal/span: eliminate TokenConverter
The TokenConverter has been trimmed down to a thin wrapper around
token.File, and can now be removed.

Robert Findley facb0d30e9 internal/span: eliminate Converter and FileConverter
The only real implementation of position conversion was via a
*token.File, so refactor the converter logic to eliminate the Converter
interface, and just use a single converter implementation that uses a
*token.File to convert between offsets and positions.

This change is meant to be a zero-impact refactoring for non-test code.
As such, I abstained from panicking in several places where it would
make sense. In later CLs, once the bug reporting API lands, we can
insert bug reports in these places.

Heschi Kreinick f7b8cc7bd0 internal/span,lsp: disambiguate URIs, DocumentURIs, and paths
Create a real type for protocol.DocumentURIs. Remove span.NewURI in
favor of path/URI-specific constructors. Remove span.Parse's ability to
parse URI-based spans, which appears to be totally unused.

As a consequence, we no longer mangle non-file URIs to start with
file://, and crash all over the place when one is opened.

Updates golang/go#33699.

Heschi Kreinick 761dbfd69d internal/span: support line directives
When //line directives are in play, the ast.File's Offset function will
return offsets in the generated file. We want offsets in the authored
file, so we need to pass a Converter for the authored file, in addition
to the ast.File for the generated file. For the same reason, we have to
start (Range).Span() by translating into positions in the authored file,
then calculate offsets from that.

A lot of call sites outside of the LSP don't pass the Converter, but
they probably don't matter much. I think everything inside does because
it ends up using mappedRange.

Updates golang/go#35720.

Ian Cottrell 6536af71d9 internal/span: end of file is now last line +1
We already accepted it as a valid input, but for output we still produced
last_line,last_column+1
Also add package docs and improve error messages

Ian Cottrell 2f43c6d1a2 internal/span: change to private fields
Change span to hide its fields and have validating accessors
This catches the cases where either the offset or the position is being used
when it was not set.
It also normalizes the forms as the API now controls them, and allows us to
simplify some of the logic.
The converters are now allowed to return an error, which lets us cleanly
propagate bad cases.
The lsp was then converted to the new format, and also had some error checking
of its own added on the top.
All this allowed me to find and fix a few issues, most notably a case where the
wrong column mapper was being used during the conversion of definition results.

This implements a standard way of describing source locations along with
printing and parsing of those locations and conversion to and from the token.Pos
