Summary: Once we're done reading the delta data, we madvise it away.
Test Plan:
dump all the hashes from a datapack into a separate file. then run a script to fetch all the delta chains. observed that the memory footprint did not increase significantly.
```
#!/usr/bin/env python
import binascii
import cdatapack
dp = cdatapack.datapack('/dev/shm/hgcache/fbsource/packs/8b5d28f7a5bd7391a0b060c88af8cca3af357c24')
for ix, line in enumerate(open('/tmp/hashes', 'r')):
line = line.strip()
dp.getdeltachain(binascii.unhexlify(line))
```
