Remove incorrect short option for --info-mode

This should be a helpValueName and not a shortOption.

Improve RemoveReset on Invalid Inits

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

This modifies RemoveReset to NOT generate a mux for
invalid (IsInvalid) inits. In the case of an invalid init, the reset
is converted to a self-connect and no mux is generated.

This is implemented as a new, initial pass over the module to populate
a set of all invalid signals. During the subsequent, circuit-modifying
pass, this invalid set is queried to special case the handling of
invalid inits.

Followup to PR #1142

- use scala.io.Source instead of io.Source
- .toList cleaner way to force stream to be read.
- clear old commented out code in ProtoBufSpec

Fixes a threading bug in where lazy reading of file
caused a problem for multithreaded access to the that was read.

Changes all uses of io.Source to use new API
getText
getLines
getTextResource
getLinesResouce

Make style to only import FileUtils and not its methods
So code is more explicit as e.g. FileUtils.getText()

- Provide new tools for reading in text
  - from a file
  - from a string file name
  - from a resource file
- text can be read in as
  - a single string with newlines
  - a seq of strings, one string per line
- FileUtils put in its own file
  - in same package to keep existing API the same

Hopefully this will protect users from creating resource leaks that
may explain sbt crashing.

Also simpler interface should make code more streamlined, existing
uses of io.Source seem often to be converting between text and seq
unnecessarily.

Add note of caution on requiring slash on resource readers

- Fixes BlackBoxSourceHelper deprecation "since"

* add multi target annotation for advices

* use Seq[Seq[Target]] store targets

* add flat function

* doc simplify

* Allow name of blackbox resource .f file to change from static value

* Restore fileListName as a deprecated def per Jack's feedback

* Support both local and absolute paths for .f resource files

This fixes a bug in the TopWiringTransform when wiring aggregates by
adding ExpandConnects to its list of fixup passes. TopWiringTransform
is MidForm => MidForm, but when wiring aggregates, it will output bulk
connects. This violates the MidForm prerequisite that ExpandConnects
has run. Symptomatically, this will manifest as match errors in
LowerTypes if a user tries to use the TopWiringTransform on
aggregates.
