6842aa006d Merge remaining dcrutil code into a dcrd package.
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.

c394c7bd19 Copy github.com/decred/dcrutil/bloom to bloom package.
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.

Update for recent chainhash-related API changes.
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.

bloom: Avoid a few unnecessary hash copies.
Contains the following upstream commits:

- 52bb44a147
  - Reverted because Travis is already on more recent versions
- e0dbb5b535
  - Reverted because txsort needs a decred-specific spec
- bdf4400eca
  - Reverted because it has already previously been cherry-picked
- 2c26dd81a5

22c91fa80a Update for recent chainhash-related API changes. (#78)
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

2c26dd81a5 bloom: Avoid a few unnecessary hash copies. (#76)
This changes several places which call the Bytes method of a ShaHash to
simply use a slice of it in order to avoid the extra unnecessary copies.

44e3030885 Fix range check in bloom filter false positive rate
Interpreting a 0 as the lower limit of 1e-9 seems more intuitive behavior when receiving an out-of-bounds argument.

3fd010412c Remove embedded bloom.Filter mutex.
This prevents the caller from being able to accidentally lock or
unlock access to the filter internal state.

While here, remove several defers that do not gain us any readability,
and only hurt our performance.
