a81cd96805 Only create signatures with even S, and verification mode to check. 
To fix a minor malleability found by Sergio Lerner (reported here:
https://bitcointalk.org/index.php?topic=8392.msg1245898#msg1245898)

The problem is that if (R,S) is a valid ECDSA signature for a given
message and public key, (R,-S) is also valid. Modulo N (the order
of the secp256k1 curve), this means that both (R,S) and (R,N-S) are
valid. Given that N is odd, S and N-S have a different lowest bit.
We solve the problem by forcing signatures to have an even S value,
excluding one of the alternatives.

This commit just changes the signing code to always produce even S
values, and adds a verification mode to check it. This code is not
enabled anywhere yet. Existing tests in key_tests.cpp verify that
the produced signatures are still valid.

159bc48193 Simplify storage of orphan transactions 
Orphan transactions were stored as a CDataStream pointer;
this changes the mapOrphanTransactions data structures to
store orphans as a CTransaction.

This also fixes CVE-2013-4627 by always re-serializing
transactions before relaying them.

5bc6d8e580 fix possible infinite loop in intro.cpp thread 
- it was possible to trigger an infinite loop in FreespaceChecker::check() by
  simply removing the drive letter on Windows (which leads to an infinite
  loop in the FreespaceChecker thread)
- this was caused by not checking if we make progress with
  parentDir.parent_path()
