[PATCH v2 0/3] Stage output for -z and new -Z options

[Paul Chaignon]

This patch set adds a new -Z option to print only failing syscalls and
fixes the current behavior of the -z option.  The output is staged, using
open_memstream, until the syscall is known to be successful or failing.

The first patch adds the -Z option, the second implements the output
staging, and the last adds two test cases.

Changelogs:
  Changes in v2:
    - Fix stage_output.c added to wrong patch.
