Switch CCoinsView and chainstate db from per-txid to per-txout
...
This patch makes several related changes:
* Changes the CCoinsView virtual methods (GetCoins, HaveCoins, ...)
to be COutPoint/Coin-based rather than txid/CCoins-based.
* Changes the chainstate db to a new incompatible format that is also
COutPoint/Coin based.
* Implements reconstruction code for hash_serialized_2.
* Adapts the coins_tests unit tests (thanks to Russell Yanofsky).
A side effect of the new CCoinsView model is that we can no longer
use the (unreliable) test for transaction outputs in the UTXO set
to determine whether we already have a particular transaction.

[test] Speed up fuzzing by ~200x when using afl-fuzz
...
Enable the `afl-clang-fast++` features deferred forkserver (`__AFL_INIT`) and persistent mode (`__AFL_LOOP(1000)`).
Before this patch:
```
$ afl-fuzz -i input -o output -m512 -- src/test/test_bitcoin_fuzzy
[*] Validating target binary...
[!] WARNING: The target binary is pretty slow! See /usr/local/share/doc/afl/perf_tips.txt.
[+] Here are some useful stats:
Test case count : 1 favored, 0 variable, 1 total
Bitmap range : 1072 to 1072 bits (average: 1072.00 bits)
Exec timing : 20.4k to 20.4k us (average: 20.4k us)
…
exec speed : 57.58/sec (slow!)
exec speed : 48.35/sec (slow!)
exec speed : 53.78/sec (slow!)
```
After this patch:
```
$ afl-fuzz -i input -o output -m512 -- src/test/test_bitcoin_fuzzy
[*] Validating target binary...
[+] Persistent mode binary detected.
[+] Deferred forkserver binary detected.
[+] Here are some useful stats:

Init ECC context for test_bitcoin_fuzzy.
...
This avoids calling things like pubkey_parse with a null context argument.
