Make InvalidateAPI emit to a test directory
Add *.swp and test_run_dir to .gitignore

Fixes #482

Closes #729

* Add issue and pull_request templates.

* Scratch itches

* Respond to review comments.

* Add Stack Overflow link.

* Add impact to issue template, type-of-change to pr.

* Reorder impact, development phase; add development phase to issue.

Also enforce switch is conditions are mutually exclusive literals

Merge branch 'master' into release

This corrects the documented example for chisel3.Driver to mixin
traits and not the related case classes.

Disambiguate DontCare reference in initializeSingletons() avoiding compilation error during unidoc generation.

Use DontCare on `outs` not `ins` in InvalidateAPISpec.
Add additional InvalidateAPISpec tests demonstrating selective override of Strict/NotStrict behavior.

* Require explicit connection to DontCare to generate "is invalid".

* Add tests for RefNotInitializedException.
Currently, we fail the when ... otherwise ...

* Disable ScalaTest shrinking on error in ComplexAssignSpec.

* fix broken merge; still some binding issues

* cleanup DontCare connection checks; add missing directions to test module IOs

* Have library code inherit compileOptions from the enclosing Module (if it exists).

* work around current firrtl uninitialized references with Strict compile options and explicitInvalidate

* more CompileOptions cleanup; move test-specific defines to package object

* minimize differences with master

* set default CompileOptions.explicitInvalidate to false until we fix the FIRRTL when issue

* ignore the StrictCompiler property checks (until  CompileOptions.explicitInvalidate is defaulted to true)

* Revert "more CompileOptions cleanup; move test-specific defines to package object"

* Revert "work around current firrtl uninitialized references with Strict compile options and explicitInvalidate"

This reverts commit 426faa430a62c3dac2dbdf33044d3386d4243157.

* remove unused code

* Convert to binding-based DontCare implementation

* comment cleanup to minimize differences with master

* Tentatively remove possibly redundant DefInvalid on module ports.

* Respond to code review change request.
- backout build.sbt change
- correct indentation
- handle bulk of DontCare semantics in elemConnect()
- have DontCare extend Element, not Data (eliminate most Object specific methods
- add comments indicating reason for explicit DontCare connections

* Initialize test elements without requiring a DontCare.

* Respond to review change requests.
- DontCare should work on left or right side in BiDirectional connections
- call bind() to set DontCare binding instead of messing with internal variables
- DontCares are only equivalent with DontCares
- clean up processWhens() definition

* Eliminate DontCare connection to inputs in MonoConnect().

* Pull aggregates apart for the purpose of DontCare connections.

* Restore the explicit (conditionally executed) ports DefInvalidin ImplicitModule()

* Don't add DontCare's to the module list of _ids.

* Add missing DefInvalid() to LegacyModule().

* Respond to review requests: add DontCare BiConnect Vec, remove null parent hack to avoid addId(), initialize singletons early in Builder

* Move DontCare out of chisel3.experimental.

Addresses #419

cloneType is now marked (through comments only) as an internal API.
chiselCloneType deprecated (and changed to cloneTypeFull internally, analogous to cloneTypeWidth).
chiselTypeOf(data) introduced as the external API to get a chisel type from a hardware object
Intended usage: cloning is an implementation detail, and chisel types and hardware objects both should act as immutable types, with operations like Input(...), Reg(...), etc returning a copy and leaving the original unchanged. Hence, the clone operations are all deprecated.
Deletes what appears to be an unused Bundle companion object.
Input(...), Output(...), Flipped(...) require the object to be unbound
