ccwl: Make #:stderr and #:stdout first class parameters.

#:stderr and #:stdout, especially #:stdout, are commonly
required. They ought to be first class parameters and not tucked away
into #:other.

* ccwl/ccwl.scm (<command>)[stderr, stdout]: New fields.
* ccwl/ccwl.scm (command): Accept #:stderr and #:stdout as first class
parameters.
* ccwl/cwl.scm (command->cwl-scm): Serialize stderr and stdout fields.
* doc/capture-stdout.scm (print),
doc/decompress-compile-run.scm (run), doc/checksum.scm (md5sum,
sha1sum, sha256sum), doc/spell-check.scm (find-misspellings): Capture
stdout in file.
* doc/checksum.scm, doc/decompress-compile-run.scm:
* doc/ccwl.skb (Tutorial)[Capturing the standard output stream of a
command]: Document #:stdout first class parameter.
* doc/ccwl.skb (Tutorial)[Workflow with multiple steps]: Capture
stdout in explicitly named files.
* tests/ccwl.scm ("commands with non-string #:stderr parameters must
raise a &ccwl-violation condition", "commands with non-string #:stdout
parameters must raise a &ccwl-violation condition"): New tests.
