Dave Collins e8bab6bc19 docs: Make various README.md files consistent.
First, it removes the documentation section from all the README.md files
and instead puts a web-based godoc badge and link at the top with the
other badges. This is being done since the local godoc tool no longer
ships with Go by default, so the instructions no longer work without
first installing godoc. Due to this, pretty much everyone uses the
web-based godoc these days anyways. Anyone who has manually installed
godoc won't need instructions.

Second, it makes sure the ISC license badge is at the top with the other
badges and removes the textual reference in the overview section.

Third, it's modifies the Installation section to Installation and
Updating and adds a -u to the go get command since it works for both and
thus is simpler.

Finally, it replaces the badges with SVG versions from shields.io so
they are consistent.

Package hdkeychain provides an API for bitcoin hierarchical deterministic
extended keys (BIP0032).
A comprehensive suite of tests is provided to ensure proper functionality. See
`test_coverage.txt` for the gocov coverage report. Alternatively, if you are
running a POSIX OS, you can run the `cov_report.sh` script for a real-time
report.
## Feature Overview
- Full BIP0032 implementation
- Single type for private and public extended keys
- Convenient cryptograpically secure seed generation
- Simple creation of master nodes
- Support for multi-layer derivation
- Easy serialization and deserialization for both private and public extended
keys
- Support for custom networks by registering them with chaincfg
- Obtaining the underlying EC pubkeys, EC privkeys, and associated bitcoin
addresses ties in seamlessly with existing btcec and btcutil types which
provide powerful tools for working with them to do things like sign
transations and generate payment scripts
- Uses the btcec package which is highly optimized for secp256k1
- Code examples including:
- Generating a cryptographically secure random seed and deriving a
master node from it
- Default HD wallet layout as described by BIP0032
- Audits use case as described by BIP0032
- Comprehensive test coverage including the BIP0032 test vectors
- Benchmarks
## Installation and Updating
```bash
$ go get -u github.com/btcsuite/btcutil/hdkeychain
```
## Examples
* [NewMaster Example]
(http://godoc.org/github.com/btcsuite/btcutil/hdkeychain#example-NewMaster)
Demonstrates how to generate a cryptographically random seed then use it to
create a new master node (extended key).
* [Default Wallet Layout Example]
(http://godoc.org/github.com/btcsuite/btcutil/hdkeychain#example-package--DefaultWalletLayout)
Demonstrates the default hierarchical deterministic wallet layout as described
in BIP0032.
* [Audits Use Case Example]
(http://godoc.org/github.com/btcsuite/btcutil/hdkeychain#example-package--Audits)
Demonstrates the audits use case in BIP0032.
