4b1f3b6b16 internal/lsp: make format work on the ast not the source
This makes the format code use the AST that is already cached on the file to do
the formatting. It also moves the core format code into the source directory.

806e1cfd89 internal/lsp: add a preliminary test for completion
Use the packagestest framework to test completion. Add support for a
slice of token.Position to packagestest to support this.

c26e340d2f internal/lsp: refactor completion and move into source directory
The completion function belongs in internal/lsp/source, so move it
there. Some small refactoring of completion, by moving each type of
completion into helper functions that append to the list of results.

d0600fd9f1 internal/lsp: make source independent of protocol
I realized this was a mistake, we should try to keep the source
directory independent of the LSP protocol itself, and adapt in
the outer layer.
This will keep us honest about capabilities, let us add the
caching and conversion layers easily, and also allow for a future
where we expose the source directory as a supported API for other
tools.
The outer lsp package then becomes the adapter from the core
features to the specifics of the LSP protocol.

6f4a86804e internal/lsp: add implementation of completion to LSP
Add an autocompletion implementation to the LSP. Also, add a function
that type-checks a package at a certain position, returning an *ast.File
and token.Pos for querying completion.

e504f914a8 internal/lsp: make file a first class concept
A file is strongly associated with a view, and knows how to manage it's own
contents.
We can also now track files that are not "active"

9b5bafe36f internal/lsp: extract view to its own package
This allows us to write the lsp verbs in terms of a stable underlying source
management layer.
This should make it easier to refactor the underlying layer to add more powerful
caching and incremental modes as we go.

ebdbadb46e internal/lsp: fix LSP tests to be compatible with Go 1.10
Change golang/go#145697 added tests for diagnostics in the LSP implementation,
but these test did not work with Go 1.10. This change skips tests that
require Go 1.11.

Any time a file is changed, we compute diagnostics for its package and
return them to the client. No caching is implemented yet, so we parse
