John Newbery 55c403b8fe Ensure -maxsigcachesize is in valid range
- If the -maxsigcachesize parameter is set to zero, setup a minimum sized
sigcache (2 elements) rather than segfaulting.
- Handle maxsigcachesize being negative
- Handle maxsigcachesize being too large

Pieter Wuille 2ddfcfd2d6 Make CScript (and prevector) c++11 movable.
Such moves are used when reallocating vectors that contain them,
for example.

Pieter Wuille 528472111b Get rid of nType and nVersion
Remove the nType and nVersion as parameters to all serialization methods
and functions. There is only one place where it's read and has an impact
(in CAddress), and even there it does not impact any of the recursively
invoked serializers.

Instead, the few places that need nType or nVersion are changed to read
it directly from the stream object, through GetType() and GetVersion()
methods which are added to all stream classes.

Pieter Wuille 657e05ab2e Make GetSerializeSize a wrapper on top of CSizeComputer
Given that in default GetSerializeSize implementations created by
ADD_SERIALIZE_METHODS we're already using CSizeComputer(), get rid
of the specialized GetSerializeSize methods everywhere, and just use
CSizeComputer. This removes a lot of code which isn't actually used
anywhere.

For CCompactSize and CVarInt this actually removes a more efficient
size computing algorithm, which is brought back in a later commit.

Pieter Wuille c2c5d42f36 Make streams' read and write return void
The stream implementations had two cascading layers (the upper one
with operator<< and operator>>, and a lower one with read and write).
The lower layer's functions are never cascaded (nor should they, as
they should only be used from the higher layer), so make them return
void instead.

Wladimir J. van der Laan 5ca8ef299a libconsensus: Add input validation of flags
Makes it an error to use flags that have not been defined
on the libconsensus API.

There has been some confusion as to what pass to libconsensus, and
(combined with mention in the release notes) this should clear it up.

Using undocumented flags is a risk because their meaning,
and what combinations are allowed, changes from release to release.
E.g. it is no longer possible to pass (CLEANSTACK | P2SH) without
running into an assertion after the segwit changes.

Mark Friedenbach 53e53a33c9 BIP112: Implement CHECKSEQUENCEVERIFY
- Replace NOP3 with CHECKSEQUENCEVERIFY (BIP112)
  <nSequence> CHECKSEQUENCEVERIFY -> <nSequence>
- Fails if txin.nSequence < nSequence, allowing funds of a txout to be locked for a number of blocks or a duration of time after its inclusion in a block.
- Pull most of CheckLockTime() out into VerifyLockTime(), a local function that will be reused for CheckSequence()
- Add bitwise AND operator to CScriptNum
- Enable CHECKSEQUENCEVERIFY as a standard script verify flag
- Transactions that fail CSV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CSV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CSV for production use.
