73adeec07e set.c: cache short deltas 
After base62+golomb decoding, most deltas are under 65536 (in Provides
versions, average delta should be around 1536).  So the whole version
can be stored using short deltas, effectively halving memory footprint.
However, this seems to be somewhat slower: per-delta copying and
decode_golomb must be invoked to recover hash values.  On the other
hand, this allows to increase cache size (128 -> 192).  But note that,
with larger cache sizes, LRU linear search will take longer.  So this is
a compromise - and apparently a favourable one.

6a9ce451bc set.c: use packed bitmap for bit vector 
Currently, set.c uses array of chars to store bit vector. Each char
stores one bit: 0 or 1.

Let's use packed bitmap instead. It creates room for optimizations.
