Remove SecureBuffer, which is the fixed-size variant of SecureVector.

Add a second template param to SecureVector which specifies the initial
length.

Change all callers to be SecureVector instead of SecureBuffer.

This can go away in C++0x, once compilers implement N2712 ("Non-static
data member initializers"), and we can just write code as

SecureVector<byte> P{18};

instead
