Prior to this commit, the testsuite was failing on OpenBSD. After
this commit the testsuite runs fine on OpenBSD.
It was previously decided to test for the OpenBSD macro (rather than
__OpenBSD__, etc.) because OpenBSD forks seem to have the former
macro defined. sys/param.h must be included for the OpenBSD macro
definition; however, many files tested for the OpenBSD macro without
having this header included.
This commit includes sys/param.h in the files where the OpenBSD macro
is used (and sys/param.h is not already included), and it also
changes some instances of the __OpenBSD__ macro to OpenBSD.
See commit 27df23abb6 which changed
everything to use OpenBSD instead of __OpenBSD__ or OPENBSD. See
also tickets #6982 and #20980 (the latter ticket is where it was
decided to use the OpenBSD macro).

In get_local_listener used by tor_ersatz_socketpair, the address
family used when binding the IPv6 socket was AF_INET instead of
AF_INET6.
Fixes bug 28995; bugfix on 0.3.5.1-alpha.

Reported on tor-dev by Gisle Vanem. Bug not in any released Tor
(The suggested patch used _MSC_VER, but that's not how we do stuff
with autoconf. With autoconf, you detect the feature you want,
rather than trying to list all the systems that do or do not have
it.)
This patch changes the CancelIoEx() example code to use CancelIo(),
which is available for older versions of Windows too. I still think the
kernel handles this nicely by sending broken pipes if either side
closes the pipe while I/O operations are pending.
See: https://bugs.torproject.org/28179
Handle `ERROR_BROKEN_PIPE` from ReadFileEx() and WriteFileEx() in
process_win32_stdin_write_done() and
process_win32_handle_read_completion() instead of in the early handler.
This most importantmly makes sure that `reached_eof` is set to true when
these errors appears.
See: https://bugs.torproject.org/28179
This patch adds some missing calls to set `reached_eof` of our handles
when various error conditions happens or when we close our handle (which
happens at `process_terminate()`.
See: https://bugs.torproject.org/28179
This patch adds some additional error checking after calls to
ReadFileEx() and WriteFileEx(). I have not managed to get this code to
reach the branch where `error_code` is NOT `ERROR_SUCCESS`, but MSDN
says one should check for this condition so we do so just to be safe.
See: https://bugs.torproject.org/28179
This patch makes us delay checking for whether we have an exit code
value (via GetExitCodeProcess()) until both stdout and stderr have been
closed by the operating system either by the process itself or by
process cleanup after termination.
See: https://bugs.torproject.org/28179
This patch makes sure that we terminate the event loop from the event
loop timer instead of directly in the process' exit handler. This allows
us to run the event loop an additional time to ensure that the SleepEx()
call on Windows is called and the data from stdout/stderr is delivered
to us.
Additionally we ensure that we don't try to read or write data from a
Unix process that have been terminated in the main loop, since its file
descriptors are closed at that time.

This patch changes the API of the Windows backend of the Process
subsystem to allow the dormant interface to disable the Process event
timer.
See: https://bugs.torproject.org/28179
This patch changes our process_t's exit_callback to return a boolean
value. If the returned value is true, the process subsystem will call
process_free() on the given process_t.
See: https://bugs.torproject.org/28179
This patch moves the remaining code from subprocess.{h,c} to more
appropriate places in the process.c and process_win32.c module.
We also delete the now empty subprocess module files.
See: https://bugs.torproject.org/28179
This patch adds a new function that allows us to reset the environment
of a given process_t with a list of key/value pairs.
See: https://bugs.torproject.org/28179
This patch makes sure that we call process_notify_event_exit() after we
have done any modifications we need to do to the state of a process_t.
This allows application developers to call process_free() in the
exit_callback of the process.
