Prevent crashes due to missing or corrupted database records
...
Any problems seen during deserialization will throw an uncaught
exception, crashing the entire bitcoin process. Properly return an
error instead, so that we may at least log the error and gracefully
shutdown other portions of the app.

Move signature cache from CKey::Verify to CheckSig in script.cpp
...
More than doubles the speed of verifying already-cached signatures
that use compressed pubkeys:
Before: ~200 microseconds
After: ~80 microseconds
(no caching at all: ~3,300 microseconds per signature)
Also encapsulates the signature cache code in a class
and fixes a signed/unsigned comparison warning.

Default to DB_TXN_WRITE_NOSYNC for all transactional operations
...
* This is safer than DB_TXN_NOSYNC, and does not appear to impact
performance.
* Applying this to the dbenv is necessary to avoid many fdatasync(2)
calls on db 5.x
* We carefully and thoroughly flush databases upon shutdown and
other important events already.

Cache signature verifications
...
Create a maximum-10MB signature verification result cache.
This should almost double the number of transactions that
can be processed on a given CPU, because before this change
ECDSA signatures were verified when transactions were added
to the memory pool and then again when they appeared in
a block.

Further DoS prevention: Verify signatures last
...
Loop over all inputs doing inexpensive validity checks first,
and then loop over them a second time doing expensive signature
checks. This helps prevent possible CPU exhaustion attacks
where an attacker tries to make a victim waste time checking
signatures for invalid transactions.
