config, mailcap: remove std/streams dependency, specialize mmap

* use PosixStream/mmap for mailcap reading too; this finally lets us get
  rid of std/streams in the entire codebase
* split up recvDataLoopOrMmap into 3 functions: one that can fall back
  to recvAll, one that falls back to recvDataLoop, and one that does not
  fall back to anything
* use MAP_PRIVATE in mmap for read (we don't care if changes are
  propagated, as we do no changes to cached files)
