Merge branch 'ob/gpg-interface-cleanup' 

strbuf_split*() to split a string into multiple strbufs is often a
wrong API to use.  A few uses of it have been removed by
simplifying the code.

* ob/gpg-interface-cleanup:
  gpg-interface: do not use misdesigned strbuf_split*()
  gpg-interface: do not use misdesigned strbuf_split*()
