Previously when you added a new file to an existing package, the new
file would get stuck with the "no package for file" error until you
saved the file and then made changed a different file in the
package. There were two changes required to fix the errors:
First, we need to invalidate the package cache when a new file is
added to a package so that the package will actually re-parse and
re-type check. We now notice if file names changed when updating a
package's metadata and invalidate the package cache accordingly.
Second, when dealing with overlay (unsaved) files, we need to map
the *goFile to the package even if we fail to parse the
file (e.g. the new file fails to parse when it is empty). If we don't
map it to the package, the package won't get refreshed as the file is
changed.

If the context is canceled (or times out) during parsing, we were
previously caching the package with no *ast.Files. Any further LSP
queries against that package would fail because the package is already
loaded, but none of the files are mapped to the package. Fix by
propagating non-parse errors as "fatal" errors in
parseFiles. typeCheck will propagate these errors and not cache the
package.
I also fixed the package cache to not cache errors loading
packages. If you get an error like "context canceled" then none of the
package's files are mapped to the package. This prevents the package
from ever getting unmapped when its files are updated. I also added a
retry mechanism where if the current request is not canceled but the
package failed to load due to a previous request being canceled, this
request can try loading the package again.

characters resulting in "foo.Bar(baz.Qux()". This is because the go
parser adds a phantom "_" identifier when parsing "foo.". We thought
the "_" was really there, so we were issuing text edits to replace
it. Fix by ignoring "_" selectors when the cursor is positioned to
their left.

For various reasons we need an internal-facing imports API. Move imports
to internal/imports, leaving behind a small wrapper package. The wrapper
package captures the globals at time of call into the options struct.
Also converts the last goimports tests to use the test helpers, and
fixes go/packages in module mode to work with empty modules, which was
necessary to get those last tests converted.

The insertion range for completion items was not right. The range's
end was 1 before the start. Fix by taking into account the length of
the prefix when generating the range start and end.
Now instead of a "prefix", we track the completion's
"surrounding". This is basically the start and end of the abutting
identifier along with the cursor position. When we insert the
completion text, we overwrite the entire identifier, not just the
prefix. This fixes postfix completion like completing "foo.<>Bar" to
"foo.BarBaz".

- We weren't including lexical completions in cases where you might be

enclosingCompositeLiteral computes all the bits of information related

Now when you accept a struct literal field name completion, you will
get a snippet that includes the colon, a tab stop, and a comma if
the literal is multi-line. If you have "gopls.usePlaceholders"
enabled, you will get a placeholder with the field's type as well.
I pushed snippet generation into the "source" package so ast and type
info is available. This allows for smarter, more context aware snippet
generation. For example, this let me fix an issue with the function
snippets where "foo<>()" was completing to "foo(<>)()". Now we don't
add the function call snippet if the position is already in a CallExpr.
I also added a new "Insert" field to CompletionItem to store the plain
object name. This way, we don't have to undo label decorations when
generating the insert text for the completion response. I also changed
"filterText" to use this "Insert" field since you don't want the
filter text to include the extra label decorations.

*snippet.Builder helps you construct lsp completion snippet strings.
It handles escaping for you, and it gives a convenient interface for
writing nested placeholders.
Note that the builder does not support snippet "variables" or
associated features. They add a lot of complexity and don't seem very
useful at this point (plus they aren't supported in many editors).

This change adds support for completion of incomplete selectors after a

Completion suppression in comments wasn't working for comments in
switch case statements, select case statements, and decl statements.
Rather than adding those to the list of leaf ast.Node types to look
for, we now always check if the position is in a comment. This fix
broke some completion tests that were using re"$" since "$" matches
after the comment "//" characters.
We now also don't complete within any literal values. Previously we
only excluded string literals.

This change propagates more errors from analyses, instead of just saving

When the value of a composite literal key/value pair was unparsable,
you were getting completions for the composite literal keys instead of
values. For example "struct { foo int }{foo: []<>" was completing to
the field name "foo". This was because the leaf ast.Node at the cursor
was the composite literal itself, and our go-back-one-character logic
was not happening because the preceding character's node
was *ast.BadExpr, not *ast.Ident. Fix by always generating the ast
path for the character before the cursor's position. I couldn't find
any cases where this broke completion.
I also added expected type detection for the following composite
literal cases:
- array/slice literals
- struct literals (both implicit and explicit field names)
- map keys and values

When jumping to definition of an embedded struct pointer, be sure to
unwrap the pointer type so you properly jump to the pointee type.
Also, fix jumping to definition of an embedded struct inside an
anonymous struct inside a struct. The embedded struct detection was
continuing too far and thinking it wasn't an embedded struct when it
saw the anonymous struct.
