* Sanitize Record._elements (#3419)

This moves name sanitation a little earlier and ensures that the
sanitized names are use more consistently throughout Chisel internals.

This fixes a bug in D/I where unsanitary names would lead to a crash.

* SRAM API: Add multiple-clocked port API (#3383)

This PR adds new APIs for the SRAM module to instantiate a number of ports connected to individual clocks. This allows the creation of memories driven by multiple clocks, for use cases like clock domain crossover.

* Deprecate calling .viewAs on non-hardware (#3395)

It's an error in most cases already, and in the cases it isn't, make it
a warning. Also fix a crash that could occur when viewing a non-Data
containing non-hardware Data.

This is not a functional bug. The recursive form of reify for Element
would use the .topBinding from the wrong argument, so it would recurse
an extra time, but it would ultimately converge to the right value.

Change what DataView allows in its type checking to enable Reset to be
viewed as either a UInt<1> or an AsyncReset.  This enables more flexible
DataViews which match already allowable Chisel and FIRRTL connection
semantics.

* Fix naming for RHS of named unapply expressions (#3163)

Previously, the naming plugin would not recurse for the RHS of an
unapply, meaning that vals declared in blocks that ultimately return
some result that is unapplied into some named Data would not be named.

Also, audit and improve the naming mdocs.
