A package really should always be associated with its snapshot rather
than its view. This eliminates some extra parameters in a few utility
functions.

This is a straight move of some code with no changes.
It splits the part of the telemetry code that will become a standalone library from the bit that belongs in the lsp.

This change configures the ordering of documentation on hover. If the
user has requested full documentation, the signature appears at the top,
to avoid the user having to scroll. Otherwise, the signature appears at
the bottom, to minimize the distance between the triggering identifier
and the signature.

Since 'IdentifierInfo' doesn't contain ast node of import spec,
gopls will construct an empty string under plaintext mode and
'```go\n\n```' under markdown mode for *ast.ImportSpec. For now,
the hovering result of import spec is the corresponding node
format.

This change adds documentation to the completion items. This normally
should be done in completionItem/resolve, since it takes more time to
compute documentation. However, I am not sure if that latency incurred
by pre-computing documentation is actually significantly more than the
latency incurred by an extra call to 'completionItem/resolve'. This
needs to be investigated, so we begin by just precomputing all of the
documentation for each item.

Instead of defaulting to a one sentence synopsis for documentation on
hover, allow the user to configure the amount of documentation they want
to see. Right now, the options are none, some (using go/doc.Synopsis),
or all. We should add a 4th, single-line, mode, which will allow clients
like vim-go to stop stripping off documentation on hover.

This change removes the explicit configuration for improved

comment.
However, we also add a "noDocsOnHover" setting that is used by the cmd
tests. Ultimately, no one should use this setting and we should remove
it. We leave it temporarily because the cmd tests still need work.

Now the "type" of a *ast.PkgName is the package it points to. Of
course, a package is not a real types.Type, but we can still jump you
there. We have to pick one of the package's files, so we choose the
longest one, hoping it is the most interesting.
Similarly, the "definition" of an *ast.ImportSpec is the package being
imported.
I also added a nil check for the package in SignatureHelp. This panics
for me occasionally.
