Subject: [PATCH] Rewrite unix fork reopen to be compatible with ruby 2.6
On ruby 2.6 the original code would fail specs:
lib/childprocess/unix/fork_exec_process.rb:32:in `reopen': exclusive
access mode is not supported (ArgumentError)
The documentation for reopen shows that it has two ways to call it:
reopen(other_IO) -> ios
reopen(path, mode [,opt]) -> ios
With ruby 2.4 and 2.5 calling reopen with a path and no mode seems to
work fine, but with ruby 2.6 this triggers the spec failure.
This commit splits the calls based on stdout/stderr availability so
that both types of reopen calls can get the required parameters. This
fixes the 2.6 specs while being backward compatible with ruby 2.4 and
2.5.
