Not everyone has `.` on their `$PATH`

curl seems to be more common and is included by default in MacOS whereas
wget is not.

Module's logic that creates the implicit clock and implicit reset within
the Module's body is now implemented in new traits that users are free
to mix in to RawModule. There are also now virtual methods implicitClock
and implicitReset that the user can override to change what clock or
reset is used.

Add OM test, support iterating fields of a OM object

Add a utility to reflect on the optional color of a layer.  This will be
used by libraries that need to know if they need to put generated logic in
a layerblock or not.

Also fix some links in the README to point to local files or at least
the main branch rather than the old master branch.

Extend the probe modifier case class, `ProbeInfo`, to include information
about the optional layer color of this layer.  Extend emission to properly
write this out to FIRRTL text.

Add a memoized (via a `lazy val`) member to Layer that returns the FIRRTL
"full name" of that layer.  This includes all the parent layers prefixed
with interleaves periods.

This is memoized to avoid unnecessarily recomputing the partial prefixes
of parents.

Refactor panama binding and converter framwork

In the future, we should rename them to org.chipsalliance...
But for now, since we need to access internal API of chisel, panama is
using the prefix of chisel3

- split binder into two projects: Java Module circtpanamabinding and
  ScalaModule panamaconverter, in the future, OMEvaultor will be split
  from converter and get rid of dependency from chisel.
- remove original test, add a small lit+FileCheck test in
  lit/tests/PanamaConveter to show how to write test.

a Pure LLVM Lit test framework

Users are now able to check whether a Data is visible from the
current context via `chisel.reflect.DataMirror.isVisible`.

* Bump versions
* It now tabs every line included in the Release Notes section of
  the PR template

Also fix website API doc link generation, links prior to 3.5.4 are not
valid (that is when we started publishing the unidoc properly so that it
gets picked up by javadoc.io and the like).

Using `Output()` shouldn't drop important type information,
only override the specified direction to force alignment.

Until #3647 is addressed, use `cloneTypeFull` to get the expected behavior.
The cloned direction information is unnecessary but is
overridden by the coerced direction.

cc #3647.
