Previously, to get the globally available declarations in a document
(including declarations from headers), we would have to recursively
walk the #include tree and get the declarations of each included
document.
To improve upon this, we now store a HashTable of globally available
declaration from included header files in each document, and populate
it when we first process the document.
Before this, invoking simple autocomplete actions in code documents
that had a very large #include tree (e.g when <LibGUI/Widget.h> was
included) hang the CppLanguageServer process and used 100% CPU until
the process ran out of memory.
Now, the autocomplete request in that situation returns immediately :^)
This enables us to use keys of type NonnullRefPtr in HashMaps and
HashTables.
This commit also includes fixes in various places that used
HashMap<T, NonnullRefPtr<U>>::get() and expected to get an
Optional<NonnullRefPtr<U>> and now get an Optional<U*>.
Have TextDocument listen for state changes on the internal undo stack,
and forward those to all clients via a new virtual function.
This simplifies updating the can_undo / can_redo states of TextEditor.
This enables support for automatically generating client methods.
With this added the user gets code completion support for all
IPC methods which are available on a connection object.
This patch removes the IPC endpoint numbers that needed to be specified
in the IPC files. Since the string hash is a (hopefully) collision free
number that depends on the name of the endpoint, we now use that
instead. :^)
Additionally, endpoint magic is now treated as a u32, because endpoint
numbers were never negative anyway.
For cases where the endpoint number does have to be hardcoded (a current
case is LookupServer because the endpoint number must be known in LibC),
the syntax has been made more explicit to avoid confusing those
unfamiliar. To hardcode the endpoint magic, the following syntax is now
used:
endpoint EndpointName [magic=1234]
This patch removes the IPC endpoint numbers that needed to be specified
in the IPC files. Since the string hash is a (hopefully) collision free
number that depends on the name of the endpoint, we now use that
instead. :^)
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

This was done with the `ambr` search and replace tool.
ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
This type represents templatized names, and replaces our previous use
of 'TemplatizedType' and 'TemplatizedFunctionCall'.
Also, we now parse function calls as secondary expressions.
- FileDB::get() now returns nullptr if the file is not in the FileDB
- Added FileDB::get_or_create_from_filesystem()
- Added FileDB::add() version that receives that file's content as a
parameter
This makes them available for use by other language servers.
Also as a bonus, update the Shell language server to discover some
symbols and add go-to-definition functionality :^)
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
