Part 1 of mega-change in #578
Major notes:
- Input(...) and Output(...) now (effectively) recursively override their elements' directions
- Nodes given userDirection (Input, Output, Flip - what the user assigned to _that_ node) and actualDirection (Input, Output, None, but also Bidirectional and BidirectionalFlip for mostly Aggregates), because of the above (since a higher-level Input(...) can override the locally specified user direction).
- DataMirror (node reflection APIs) added to chisel3.experimental. This provides ways to query the user given direction of a node as well as the actual direction.
- checkSynthesizable replaced with requireIsHardware and requireIsChiselType and made available in chisel3.experimental.
Internal changes notes:
- toType moved into Emitter, this makes the implementation cleaner especially considering that Vec types can't be flipped in FIRRTL. This also more clearly separates Chisel frontend from FIRRTL emission.
- Direction separated from Bindings, both are now fields in Data, and all nodes are given hierarchical directions (Aggregates may be Bidirectional). The actualDirection at the Element (leaf) level should be the same as binding directions previously.
- Bindings are hierarchical, children (of a, for example, Bundle) have a ChildBinding that points to their parent. This is different than the previous scheme where Bindings only applied at the Element (leaf) level.
- Lots of small misc clean up.
Future PRs will address other parts of #578, including stricter direction checks that aren't a side-effect of this internal refactor, stricter checks and splitting of binding operations (Wire vs. WireInit), and node operations not introduced here (getType and deprecation of chiselCloneType). Since those shouldn't mess with internals, those should be much smaller.

* Remove explicit import of NotStrict - fixes #492
* Provide macro for MemBase.apply().
* Provide macro for MemBase.apply().
Since a macro cannot override an abstract method, provide a concrete
apply method n VecLike() that we can override with a macro.
* Remove concrete apply() in VecLike.
Since MemBase no longer extends the trait VecLike, we do not require a concrete method to which we can apply a macro to extract the appropriate CompileOptions.

withClockAndReset, withReset, and withClock allow changing the implicit clock and reset.
Module.clock and Module.reset provide access to the current implicit clock and reset.

Used for stitching Verilog inout through Chisel Modules (from BlackBox
to BlackBox)

Retain un-deprecated SeqMem in compatibility mode, deprecate in chisel3.

|
* Name propagation
* chiselName everywhere at best-effort level
* Better collision handling
* Allow recursing into inner anonymous functions
* Add for loop and anonymous inner function tests

Record gives uses the power to create collections of heterogenous elements.
Bundle is a special case of Record that uses reflection to populate the
elements of the collection. Bundle also attempts to implement cloneType whereas
users of Record are required to supply one.

* Mark Annotation and FixedPoint as experimental
Fix tests and other references to these constructs
* Made experimental imports more specific where possible
|
|

* Support for creating chisel annotations that are consumed by firrtl
Update annotation serialization in Driver
Add DiamondAnnotation Spec that illustrates how to do simple annotations
frontEnd must have dependency on firrtl
Add annotation method to Module
Circuit has extra optional parameter that is Seq of Annotations
In Builder add annotation buffer to DynamicContext to store annotations created in modules
Added explicit types on naming api methods to avoid type confusion
Because some names are not available until elaboration create intermediate ChiselAnnotation that
gets turned into a firrtl Annotation after elaboration
In execute pass firrtl text and annotation to firrtl are now passed in through optionManager, though
intermediate file .fir and .anno files are still created for inspection and/or later use
* Somehow missed ChiselAnnotation
* fixes for Jack's review of PR

Also restrict black boxes to not allow hardware inside of them since it was
being silently dropped anyway.
Resolves #289

* FixedPoint number support for chisel3
FixedPoint numbers have a width and a binary position
Either, neither or both maybe inferred.
Firrtl will convert these to SInts during lowering passes
* Fixes based on Jack's comments on PR #328
* Add experimental warning to FixedPoint class and object
* Fixed comment per Adam's comment on PR #328

Printable is a new type that changes how printing of Chisel types is represented
It uses an ordered collection rather than a format string and specifiers
Features:
- Custom String Interpolator for Scala-like printf
- String-like manipulation of "hardware strings" for custom pretty-printing
- Default pretty-printing for Chisel data types
