This change moves the suggested fixes logic for fillstruct out of the
analysis and into internal/lsp/source. This logic is then used as part
of a new fillstruct command. This command is returned along with the
code action results, to be executed only when the user accepts the code
action.
This led to a number of changes to testing. The suggested fix tests in
internal/lsp doesn't support executing commands, so we skip them. The
suggested fix tests in internal/lsp/source are changed to call
fillstruct directly. A new regtest is added to check the command
execution, which led to a few regtest changes.
Also, remove the `go mod tidy` code action, as it's made redundant by
the existence of the suggested fixes coming from internal/lsp/mod.

Completion could be slow due to calls to astutil.PathEnclosingInterval
for every candidate during formatting. There were two reasons we
called PEI:
1. To properly render type alias names, we must refer to the AST
because the alias name is not available in the typed world.
Previously we would call PEI to find the *type.Var's
corresponding *ast.Field, but now we have a PosToField cache that
lets us jump straight from the types.Object's token.Pos to the
corresponding *ast.Field.
2. To display an object's documentation we must refer to the AST. We
need the object's declaring node and any containing ast.Decl. We
now maintain a special PosToDecl cache so we can avoid the PEI call
in this case as well.
We can't use a single cache for both because the *ast.Field's position
is present in both caches (but points to different nodes). The caches
are memoized to defer generation until they are needed and to save
work creating them if the *ast.Files haven't changed.
These changes speed up completing the fields of
github.com/aws/aws-sdk-go/service/ec2 from 18.5s to 45ms on my laptop.

Add a symbolStyle configuration option, and use it to parameterize the
following behavior when computing workspace symbols:
+ package (default): include package name in the workspace symbol.
+ full: fully qualify the symbol by import path
+ dynamic: use as the symbol the shortest suffix of the full path that
contains the match.
To implement this, expose package name in the source.Package interface.
To be consistent with other handling in the cache package, define a new
cache.packageName named string type, to avoid confusion with packageID
or packagePath (if confusing those two identifiers was a problem, surely
it is a potential problem for package name as well).

We use file identities pervasively throughout gopls. Prior to this
change, the identity is the modification date of an unopened file, or
the hash of an opened file. That means that opening a file changes its
identity, which causes unnecessary churn in the cache.
Unfortunately, there isn't an easy way to fix this. Changing the
cache key to something else, such as the modification time, means that
we won't unify cache entries if a change is made and then undone. The
approach here is to read files eagerly in GetFile, so that we know their
hashes immediately. That resolves the churn, but means that we do a ton
of file IO at startup.
Incidental changes:
Remove the FileSystem interface; there was only one implementation and
it added a fair amount of cruft. We have many other places that assume
os.Stat and such work.
Add direct accessors to FileHandle for URI, Kind, and Version. Most uses
of (FileHandle).Identity were for stuff that we derive solely from the
URI, and this helped me disentangle them. It is a *ton* of churn,
though. I can revert it if you want.

WorkspaceSymbols matches symbols across views using the given query,
according to the matcher Matcher.
The workspace symbol method is defined in the spec as follows:
> The workspace symbol request is sent from the client to the server to
> list project-wide symbols matching the query string.
It is unclear what "project-wide" means here, but given the parameters
of workspace/symbol do not include any workspace identifier, then it has
to be assumed that "project-wide" means "across all workspaces". Hence
why WorkspaceSymbols receives the views []View.
However, it then becomes unclear what it would mean to call
WorkspaceSymbols with a different configured Matcher per View.
Therefore we assume that Session level configuration will define the
Matcher to be used for the WorkspaceSymbols method.

FindAnalysisError, we add an ErrorMatch function to source.Analyzer.
This is not an ideal solution, but it was the best one I could come up
with without modifying the go/analysis API. analysisinternal could be
used for this purpose, but it seemed to complicated to be worth it, and
this is fairly simple. I think that go/analysis itself might need to be
extended for type error analyzers, but these temporary measures will
help us understand the kinds of features we need for type error
analyzers.
A follow-up CL might be to not add reports for type error analyzers
until the end of source.Diagnostic, which would remove the need for the
look-up.

A consequence of this change is that we can have one directory separated by folders, where each folder is it's own module, this allows us to use internal/lsp/tests with go.mod files.

The passed-in Context is not used, and creates the illusion of a startup
dependency problem: existing code is careful to pass in the context
containing the correct Client instance.
This allows passing in a source.Session, rather than a source.Cache,
into lsp server constructors.

The main goal is to push the package variant logic from internal/lsp
into internal/lsp/source so all users of internal/lsp/source benefit.
"references" and "rename" now have top-level source.References() and
source.Rename() entry points (as opposed to hanging off
source.Identifier()). I expanded objectsAtProtocolPos() to know about
implicit objects (type switch and import spec), and to
handle *ast.ImportSpec generically. This gets rid of special case
handling of *types.PkgName in various places.
The biggest practical benefit, though, is that "references" no longer
needs to compute the objectpath for every types.Object comparison it
does, instead using direct types.Object equality. This speeds up
"references" and "rename" a lot.
Two other notable improvements that fell out of not using
source.Identifier()'s logic:
- Finding references on an embedded field now shows references to the
field, not the type being embedded.
- Finding references on an imported object now works
correctly (previously it searched the importing package's dependents
rather than the imported package's dependents).
Finally, I refactored findIdentifier() to use pathEnclosingObjNode()
instead of astutil.PathEnclosingInterval. Now we only need a single
call to get the path because pathEnclosingObjNode() has the
"try pos || try pos-1" logic built in.

In cases like:
var foo *someType = bar.(some<>)
We will now complete "some" to "*someType". This involved two changes:
1. Properly detect expected type as *someType in above example. To do
this I just removed *ast.TypeAssertExpr from
breaksExpectedTypeInference() so we continue searching up the AST for
the expected type.
2. If the given type name T doesn't match, also try *T. If *T does
match, we mark the candidate as "makePointer=true" so we know to
prepend the "*" when formatting the candidate.

This change moves to our ultimate approach of diagnostics the snapshot
on every file change, instead of carefully picking which files and
packages to diagnose. Analyses are shown for packages whose files are
open in the editor. Reverse dependencies are no longer needed for
source.Diagnostics because they will be invalidated when the snapshot is
cloned, so diagnosing the entire snapshot will bring them up to date.
This even works for go.mod files because all of workspace-level `go list`s
will be canceled as the user types, and then we trigger an uncancellable
go/packages.Load when the user saves. There is still room for improvement
here, but it will require much more careful invalidation of metadata for
go.mod files.

In golang.org/cl/209419, CheckPackageHandle was renamed to
PackageHandle, but a number of references to CheckPackageHandle remained
in function names and comments.
This CL cleans up most of these, though there was at least one case
(internal/lsp/cache.checkPackageKey) where the obvious renaming
conflicted with another function, so I skipped it.

This change flattens the completion options type into UserOptions and
DebuggingOptions, which will enable us to generate documentation for
these options more effectively. This results in some modifications in
the tests.
Additionally, the fuzzyMatching and caseSensitive boolean flags are
merged into one setting, matcher, which can be used to specify the type
of matcher that is used for completion. Other requests (notably
workspaceSymbols) may need to use a matcher in the future.

There is no reason for these functions to live on the view. They make
more sense as unexported functions in internal/lsp/source.
Initially, I had to propagate contexts through a lot of functions in
internal/lsp/source, but instead I removed the unused contexts forom
snapshot.GetFile.

This change splits source.Diagnostics into source.FileDiagnostics and

but this just simplifies the process of getting diagnostics if you only
