  lib: Fixed potential crash in i_stream_stat() failures.

We shouldn't have been copying parent's stream_errno here. Especially
because the parent can be NULL.

  Log Message:
  -----------
  lib-fs: Make sure fs-metawrap catches all write errors.

The full istream may not have been written in case ostream only partially
wrote the data (e.g. out of disk space?)

    M src/lib/istream-seekable.c

  Log Message:
  -----------
  lib: Fixed istream_seekable.stat() to return correct size.

It was supposed to read until end of the stream, but it did it only when
stat() was called while stream was still fully in memory.
