7b52ccbfc4 Revert "gio, glib: Use G_OS_DARWIN for code that is for such environments"
This reverts commit 476e33c3f3.

We’ve decided to remove `G_OS_DARWIN` in favour of recommending people
use `__APPLE__` instead. As per the discussion on #2802 and linked
issues,
 * Adding a new define shifts the complexity from “which of these
   platform-provided defines do I use” to “which platform-provided
   defines does G_OS_DARWIN use”
 * There should ideally be no cases where a user of GLib has to use
   their own platform-specific code, since GLib should be providing
   appropriate abstractions
 * Providing a single `G_OS_DARWIN` to cover all Apple products (macOS
   and iOS) hides the complexity of what the user is actually testing:
   are they testing for the Mach kernel, the Carbon and/or Cocoa user
   space toolkits, macOS vs iOS vs tvOS, etc

476e33c3f3 gio, glib: Use G_OS_DARWIN for code that is for such environments
While we preserved the COCOA/CARBON cases when specific libraries are
needed.

81f614533d Define G_IOV_MAX to 512 on macOS/iOS
For macOS/iOS, UIO_MAXIOV is documented in writev(2), but <sys/uio.h> only
declares it if defined(KERNEL)

20a2c379c4 Clamp number of vectors to IOV_MAX / UIO_MAXIOV for GOutputStream writev() calls in the implementations
More vectors will give an error and we can simply clamp here and
consider it like a short write instead.

In case of GSocketOutputStream this is done here instead of inside
GSocket before calling sendmsg() because we we can't generically handle
short writes when sending messages on a socket, e.g. for datagram
sockets this causes only part of the datagram to be sent and an error
would be more useful in this case than sending corrupted data.

Also reduce the fallback limit to 16 in gsocket.c as that's the minimum
value required by POSIX and add a static assertion that the limit is
never bigger than G_MAXINT as that's the type recvmmsg/sendmmsg take.

0bcc177378 Add writev() / writev_all() API to GOutputStream and GPollableOutputStream
This comes with default implementations around the normal write
functions and async variants.

cb40c553ae streams: add private 'async close via threads' API
Add an internal helper to find out if close_async() is implemented via
threads using the default implementation in the base class.

We will use this to decide if we should do a 'pure async' close of a
GIOStream or not.

a46459b000 GSocketClient: For _CONNECTING event, make remote address accessible
My application (hotssh) would like to get the resolved address from DNS,
before we start the connect().

We could add a new event, but it's easy enough to just cache it on the
GSocketConnection; this avoids any new API.

dec3bfeebc GOutputStream: Add g_output_stream_async_write_is_via_threads()
In implementing a better g_output_stream_splice_async() and possibly
other situtations it's helpful to know whether the output stream's
write function internally uses threads. If it and the input stream's
read async functions use threads, then the splice function could
spawn a single thread for better efficiency.

This patch adds a function to determine whether an output stream's
g_output_stream_write_async() function internally uses threads.
