The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.

We can optimize verifying multiple multisignatures by splitting the

data building into two parts;
|
|
o A large part that is shared by all of the computations.
|
|
o A small part that is unique to each signer in the multisignature.

|
|
1. startMultiSigningData provides the large part which can be shared.
|
|
2. finishMultiSigningData caps the passed in serializer with each
|
|
signer's unique data.
