Subject: [PATCH] Support retrieving the spec contents in parsed format

- Collect the preprocessed (conditionals, macros etc evaluated)
  lines to a separate stringbuf, make rpmSpecGetSection() return
  that on RPMBUILD_NONE "section" (hack, but so is abusing RPMBUILD_FOO
  for the section here so shrug)
