On MacOS the default open file limit is 256 files per process. For big
projects this could cause issues when reading all files (more or less)
at the same time.
By moving up the `parseLimit` so the reading of the file is only done
when it is allowed to start parsing the file, we stay well below the 256
files per process (as the `parseLimit` is currently set to 20).
Since `parseLimit` is actually only used to limit IO access, let's also
rename the const to `parseLimit`.

The `files` slice is used twice. First it's used to get all results from `ph.Parse`, and then it's reused to filter all `nil` values (which may have been returned by the `ph.Parse` method).
After the loop to "filter" out all the `nil` values, we also need to strip the remaining values.
I also changed the ordering so that we first check the errors and
only then perform this loop. That way the code will return earlier
when the context was canceled.
Partially fixes#33531 by prevention the panic reported in that issue.

If typeCheck() returned an error, we could get into a state where a
package had an entry in the pcache, but the package's files had an
empty "pkgs" map. When we got a DidChange event for one of the files,
no packages would get invalidated since the file's "pkgs" was
empty. This resulted in the cached typeCheck() error persisting
indefinitely. Fix by never caching pcache entries on error.
An easy way to reproduce the problem was to delete the package name
from a file. For example, edit "package foo" to be just
"package". This caused the package to get stuck with an "AST for %s
has an invalid position" error.

2. (*goFile).invalidateContent() acquires the "handleMu" mutex first and
then the "mcache" mutex.
Fix by changing the acquisition order in invalidateContent().
The second deadlock involved the file watcher. The two code paths
involved were:
1. (*goFile).GetPackages() holds the view mutex and eventually calls
(*WatchMap).Watch, which acquires the watcher mutex.
2. (*session).openOverlay acquires the watcher mutex as it triggers a

"(*goFile).invalidateContent" acquires the view mutex.

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

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.

import statements had changed. This was causing us to not refetch a
package's metadata when needed in certain cases. In particular, if you
typed out an import path by hand you would get stuck with "no metadata

metadata refresh.

We panic if the uri was not a valid file uri instead
They always are a valid file URI, and we would fail miserably to cope if they were
not anyway, and there are lots of places where we need to be able to get the filename
and don't want to cope with an error that cannot occur.
If we ever have not file uri's, you will have to check if it is a file before calling
.Filename, which seems reasonable anyway.

This change marks any unresolved packages discovered as imports by
go/packages.Load. It re-runs go/packages.Load for any package with
missing imports, which will result in the LSP registering changes in
dependencies.
However, this means that we re-run go/packages.Load on
package's with unresolved imports much more than we normally would, so
it may result in a slowdown or unexpected behavior. I'm not sure if this
is necessarily the correct approach here.

This change trims the function bodies from the ASTs of files belonging to
dependency packages. In these cases, we do not necessarily need full
file ASTs, so it's not necessary to store the function bodies in memory.
This change will reduce memory usage. However, it will also slow down
the case of a user opening a file in a dependency package, as we will
have to re-typecheck the file to get the full AST. Hopefully, this
increase in latency will not be significant, as we will only need to
re-typecheck a single package (all the dependencies should be cached).

The "analyses" cache in lsp/cache.(*Package).GetActionGraph was not
getting cleared on errors. This could result in future calls to
GetActionGraph waiting on the "ready" channel indefinitely. This in
turn caused the goroutine in cacheAndDiagnose to block indefinitely
and never send the diagnostic results back.
Now we use a defer statement to always close the channel. If we did
not succeed, we also clear out the cache entry and set a "succeeded =
false" flag to signal waiters that they need to retry. If in the
future errors other than context.Canceled/Timeout are possible, this
retry behavior may need to be revisited.
