This may have been causing an intermittent failure of the pollable test
on BSD, where updating the readable status of a socket takes a bit
longer than on Linux.
```
GLib-GIO-DEBUG: 16:06:41.235: GSocketClient: Starting application layer connection
GLib-GIO-DEBUG: 16:06:41.235: GSocketClient: Connection successful!
Bail out! GLib-GIO:ERROR:../gio/tests/pollable.c:73:check_source_readability_callback: assertion failed (readable == expected): (0 == 1)
```
I have not debugged the test on BSD, though, so this is only a guess.

This should make each unit test a bit more self-contained and easier to
verify that they’re independent.

Helps: #1415
The SONAME of libutil varies between architectures, so the logic to find
the SONAME of libutil was only correct for native builds (Linux on
Linux), not for cross-builds. The regular expression was also not
sufficiently broad to match the SONAME used on the alpha architecture,
which is apparently libutil.so.1.1.
Instead of screen-scraping the output of ldconfig and using that to
dlopen the library that contains openpty, it seems more reliable to
emit a link-time reference to openpty and let the linker do its job.
It's also less code.

Calling `dlopen()` with `libutil.so` makes the installed tests depend on
having glibc's development files installed. To avoid this, we can work
out the runtime library name at build time and `dlopen` that instead.
This approach is [taken from libfprint][1], thanks to Marco Trevisan.

For non-Linux UNIX systems, the label 'close_libutil:' in
'test_pollable_unix_pty()' will have no statement that goes with that
label. Just do a 'return' on non-Linux UNIX systems.
Some editors automatically remove trailing blank lines, or
automatically add a trailing newline to avoid having a trailing
non-blank line that is not terminated by a newline. To avoid unrelated
whitespace changes when users of such editors contribute to GLib,
let's pre-emptively normalize all files.
Unlike more intrusive whitespace normalization like removing trailing
whitespace from each line, this seems unlikely to cause significant
issues with cherry-picking changes to stable branches.

This checks if the stream is writable before writing
to it. If the write succeeded with no error, then the
stream has to be also writable after the write
Spotted when temporarily compiling with -Wwrite-strings. This only goes
a small way towards making the code base -Wwrite-strings–clean. It
introduces no functional changes, and fixes no bugs.

Darwin's poll doesn't change revents if there are no available events, though it returns 0. Initialize the fd.revents to 0 so that the test passes.
That reveals a test failure, though, because with socket streams it takes time for an event to pass through the socket. Provide an 80-usec delay to allow time for the propagation.
Very many testcases, some GLib tools (resource compiler, etc) and
GApplication were calling g_type_init().
Remove those uses, as they are no longer required.

Because it now handles EINTR. And we should do so. While most people
use Linux, which tries very hard to avoid propagating EINTR back up
into userspace, it can still happen.

When interfacing with APIs that expect unix-style async I/O, it is
useful to be able to tell in advance whether a read/write is going to
block. This adds new interfaces GPollableInputStream and
GPollableOutputStream that can be implemented by a GInputStream or
GOutputStream to add _is_readable/_is_writable, _create_source, and
_read_nonblocking/_write_nonblocking methods.
Also, implement for GUnixInput/OutputStream and
GSocketInput/OutputStream
