Convert if/else-if chains to typed switch statements (staticcheck QF1003) (#2112) 
Replaces 100+ if/else-if chains on a single variable with tagged switch
statements across 72 files. The bulk are transformer option-parsing loops
(switch on opt string), plus a handful of value-dispatch sites in mlrval,
dsl/cst, repl, lib, auxents, and bifs. One case (surv.go) required a
labeled break to preserve the loop-exit behavior of the original else branch.

Fixes staticcheck QF1003 findings.

Logic for transforming input records into output records as requested by the user (sort, filter, etc.).:

  • The IRecordTransformer abstract record-transformer interface datatype, as well as the ChainTransformer Go-channel chaining mechanism for piping one transformer into the next.
  • The transformer lookup table, used for Miller command-line parsing, verb construction, and online help.
  • All the concrete record-transformers such as cat, tac, sort, put, and so on.
