This diff addresses the issue of the ever increasing memory usage of clangd. The key to understand what happens is to use `malloc_stats()`: malloc arenas keep getting bigger, although the actual memory used does not. It seems some operations while bulding the indices (both dynamic and background) create this problem. Specifically, 'FileSymbols::update' and 'FileSymbols::buildIndex' seem especially affected.
This diff adds a call to `malloc_trim()` periodically in
ClangdLSPServer.
