1. Fixed a bug on building document symbol tree: As sym2ds was updated in
place, nested funcs/types may be moved into children of another
lsDocumentSymbol before itself got processed.
2. Namespaces only have declarations, in the old implementation it wasn't included in the result, making the result less hierarchical. This
commit fixes this by including the declarations of a symbol if no
definitions found.
Before, QueryFile::Def::{all_symbols,outline} were built by indexers.
Now, {symbol,outline}2refcnt are used instead, built by main thread.
*_removed are augmented with Query*:Def to allow removal of old {symbol,outline}2refcnt entries.
