Nick Mathewson efbd4a33f4 Raise MIN_DL_PER_REQUEST to 32
This change should improve overhead for downloading small numbers of
descriptors and microdescriptors by improving compression
performance and lowering directory request overhead.

Closes ticket 23220.

o Minor features (client directory bandwidth tuning):
- When downloading (micro)descriptors, don't split the list of
descriptors into multiple requests unless there are at least 32
descriptors that we want. Previously, we split at 4, not 32, which
could lead to significant overhead in HTTP request size and
degradation in compression performance. Closes ticket 23220.
