phabricator: try to fetch differential revisions in batch Previously, we read Differential Revisions one by one by calling `differential.query`. Fetching them one by one is suboptimal. Unfortunately, there is no Conduit API that allows us to get a stack of diffids using a single API call. This patch tries to be smarter using a simple heuristic: when fetching D59 as a stack, previous IDs like D51, D52, D53, ..., D58 are likely belonging to a same stack so just fetch them as well. Since `differential.query` only returns cheap metadata without expensive diff content, it shouldn't be a big problem for the server. Using a test Phabricator instance, this patch reduces `phabread` reading a 10 patch stack from about 13 to 30 seconds to 8 seconds.
