* Add sbt-api-mappings plugin

This adds the sbt-api-mappings plugin which enables
auto-linking (properly setting the apiMappings for the sbt project) so
that Scaldoc/unidoc generation will now automatically link against
Java and Scala API docs (and use the right version).

No more compile internal

* Rename coreMacros to macros
* Rename chiselFrontend to core

Also make each subproject publish with "chisel3-" as a prefix

This has the effect of causing the coreMacros and chiselFrontend
projects to be published separately

Deprecate Driver methods in favor of ChiselStage

This adds three new methods to ChiselStage to replace deprecated
methods in the Driver for converting a Chisel circuit to a string:
  - emitChirrtl
  - emitFirrtl
  - emitVerilog

This also adds a ChiselStage companion object that lets you generated
a Chisel Circuit or a FIRRTL Circuit from a Chisel module:
  - elaborate
  - convert

squash! Add string emission helper methods to ChiselStage

* Remove toNamed (and friends) deprecation.

* Add inadvertently deleted leading double quote.

* Remove commented out deprecations.

Add trait chisel3.experimental.NoChiselNamePrefix which causes
@chiselName to skip naming of the instance effectively preventing it
from prefixing any vals inside the instance. It can be applied to
classes such that all instances of that class have this property, or to
individual instances (via creating an anonymous class inline).

Also add basic ScalaDoc for NoChiselNamePrefix and chiselName.

Change the logic for determining which nested ChiselException cause to
use for a trimmed stack trace. Previously, this would use the
outermost. This commit changes this to use the innermost.

Change ChiselException.builderName to compute the name of Chisel's
internal Builder as opposed to hard-coding this with a string.

Adds two tests:

  1. Test that an internal requirement failure (a bare exception) inside
     a Builder is properly reported/trimmed by ChsielStage/ChiselMain
  2. Test that the full stack trace includes the ChiselException

Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

Changes the behavior of ChiselException stack trace trimming to use
either the first exception that includes a method from the Builder or
the outer exception.
