Mike Kaganski d84deb9536 Use std::vector in SbiBuffer
This removes memory management from the class; unifies the types
used throughout the code using it; and simplifies it all greatly.

Also this changes errors handling. Prevoiusly setting errors to
parser didn't handle case when no parser was passed to SbiBuffer
ctor, as BufferTransformer did, and could dereference nullptr.
