This merge commit adds the following code from the
github.com/decred/dcrutil package into a new
github.com/decred/dcrd/dcrutil package:
* Address handling
* Amount type
* AppDataDir func
* bitflags functions
* Block wrapper type
* Hash160 func
* Tx wrapper type
* WIF type
as well as all tests for this code.
The old github.com/decred/dcrutil/hdkeychain package has also been
merged and moved to github.com/decred/dcrd/dcrutil/hdkeychain.
dcrd packages have been updated to use the new packages and the dep
files have been updated for this change.
Use this new bloom package rather than relying on the bloom package
from the dcrutil repo.
Some minor source code changes have been made to conform to the dcrd
linter requirements.
Upstream commit 22c91fa80a.
Also, in keeping with the spirit of the upstream commits, the merge
commit also renames all other instances of variables and function names
that have sha in their names to include hash instead. This is
particularly beneficial for Decred because decred uses blake for hashing
instead of sha.
Contains the following upstream commits:
- ff82dacded
- This is a NOOP since it was previously cherry-picked
- 2d190f72ff
- This is a NOOP since it was previously cherry-picked

This updates all code in the main package and subpackages to make use of
the new chainhash package since the old wire.ShaHash type and functions
have been removed in favor of the abstracted package.
Also, since this required API changes anyways and the hash algorithm is
no longer tied specifically to SHA, all other functions throughout the
code base which had "Sha" in their name have been changed to Hash so
they are not incorrectly implying the hash algorithm.
The following is an overview of the changes:
- Update all references to wire.ShaHash to the new chainhash.Hash type
- Rename the following functions and update all references:
- Block.Sha -> Hash
- Block.TxSha -> TxHash
- Tx.Sha -> Hash
- bloom.Filter.AddShaHash -> AddHash
- Rename all variables that included sha in their name to include hash
instead
- Add license headers to coinset package files
I have commented out 1 test in bloom/filter_test.go for
TestFilterInsertP2PubKeyOnly since we don't currently have
a good tx to test that with
Also commented out Hybrid and Uncompressed pubkey testing
since they are not working correctly with our structure.
ScriptAddresses aren't returning properly from them.
Interpreting a 0 as the lower limit of 1e-9 seems more intuitive behavior when receiving an out-of-bounds argument.
