If the cursor is right before the "." in a member access expression,
clangd interprets it as belonging to the member instead of the base
expression, which leads to unexpected behavior.
Work around this by sending a cursor position one to the left of the
real one to clangd in such cases.

with an id always send a response to the server either with the result
or with an error. Also make sure to not send responses to unreachable

When I get a slowdown while typing, it is usually accompanied by the
clangd message "Request cancelled because the document was modified"
occurring in the message window, often many times in a row. I'd like to
find out whether writing to the message window itself is a contributing
factor to the slowdown.

Since we use the AST in several contexts, it can easily happen that we
need to consult it more than once for the same document revision.
Therefore, it makes sense to cache the AST to prevent redundant requests
for potentially large amounts of data.

Due to the potential cost of the re-highlighting procedure, we'd like to
delay the semantic tokens update request to a time where the new token
information won't get invalidated right away due to further document
changes. While the document updates in principle have such a delay
already, it is often "sabotaged", for instance due to auto-completion
requests which require the server to know the current document contents
right away.
Therefore, we request new semantic tokens along with a document update
only if it's the "regular" delayed one, and otherwise add an additional
delay.

Opening a document in the language client while the server is still
initializing will postpone the opening after the server is fully
initialized. So if a document was scheduled for opening by
ClangModelManagerSupport::onEditorOpened while clangd is still
initializing, skip the superfluous opening in the ClangdClient
initialize callback. Clangd seems to have issues if files are opened
twice, resulting in strange diagnostics after editing the file. This is
reproducible for me when starting Qt Creator with a session that
contains open files.
