New versions of OpenSSL will reject non-canonical DER signatures. However,
it'll happily decode them. Decode then re-encode before verification in order
to ensure that it is properly consumed.

fe925e2 Use EXTRA_LIBRARIES instead of noinst_LIBRARIES so we can avoid building unused code (Cory Fields)
on rare occasions, rand() was returning duped values, causing duplicate
transactions.
BuildMerkleTree happily used these, but CPartialMerkleTree caught them and
returned a null merkle root.
Rather than taking changes with rand(), use the loop counter to guarantee
unique values.
At sipa's request, also remove the remaining uses of rand().

Instead of using a fixed-width font in a label, which virtually
guarentees a horizontal scrollbar, use a proper text-document
that can re-layout based on user input.

5d3064b Temporarily add SetNull/IsNull/GetCheapHash to base_uint (Wladimir J. van der Laan)
Remove initialization from vector (as this is only used in the tests).
Also implement SetHex and GetHex in terms of uint256, to avoid
duplicate code as well as avoid endianness issues (as they
work in term of bytes).
- Methods that access the guts of arith_uint256 are removed,
as these are incompatible between endians. Use uint256 instead
- Serialization is no longer needed as arith_uint256's are never
read or written
- GetHash is never used on arith_uint256
If uint256() constructor takes a string, uint256(0) will become
dangerous when uint256 does not take integers anymore (it will go
through std::string(const char*) making a NULL string, and the explicit
keyword is no help).
SignatureHash and its test function SignatureHashOld
return uint256(1) as a special error signaling value.
Return a local static constant with the same value instead.
Previous behavior with IsFinalTx() being an IsStandard() rule was rather
confusing and interferred with testing of protocols that depended on
nLockTime.
Otherwise, if CCoinsViewCache::ModifyCoins throws an exception in between
setting hasModifier and constructing the CCoinsModifier, the cache ends up
in an inconsistent state, resulting in an assert failure in the next
modification.
