dynamic tables: improve error handling by returning base::Status from ComputeTable Also make ancestor, descendant, and annotated callstack generators handle invalidly typed inputs (most likely a stray null) with an explicit error, instead of a crash on SqlValue.AsLong(). Most of the other generators were made to work as before, without taking advantage of the new Status error reporting. Examples of errors: > select * from ancestor_slice(null) SQLite error: ancestor_slice: invalid start_id (errcode: 19) > select * from ancestor_slice(420000) SQLite error: ancestor_slice: no row with id 420000 (errcode: 19) Tested: difftests and unittests Bug: 218988616 Change-Id: Ie50fac38dfc2af736d3c42cc7c7880c12abca61b
