26991b6093 win32 gpoll: Fix wait for at least one thread to return
When timeout grater than 0 in g_poll function, the WaitForMultipleObjects
call will wait for all the threads to return, but when only one thread
got an event the others will sleep until the timeout elapses, and causes
a stall. Triggering the stop event in g_poll in this case is useless as
it is triggered when all the threads where already signaled or timed-out.

24714b50df win32 gpoll: overcome the 64 handles limit
This is a new polling method allowing to poll more than 64 handles
based on the glib one.
When we reach the limit of 64 we create a thread and we poll
on that thread for a batch of handles this way we overcome the limit.

9b4c50f63d all: Remove trailing newlines from g_message()/g_warning()/g_error()s
All those logging functions already add a newline to any message they
print, so there’s no need to add a trailing newline in the message
passed to them.

b267f648d9 glib/gpoll W32: trust WFMOE() return value
WaitForMultipleObjectsEx() returns the index of the *first* handle that triggered the wakeup, and promises that all handles with lower index are still inactive. Therefore, don't check them, only check the handles with higher index. This removes the need of rearranging the handles (and, now, handle_to_fd) array, it's enough to take a pointer to the next item and use it as a new, shorter array.

226ea94685 glib/gpoll W32: faster GPollFD lookup
Put all ptrs for GPollFDs that contribute handles into an array, the layout of which mirrors the handles array. This way finding GPollFD for a handle is a simple matter of knowing this handle's index in the handles array (which is something we always know). Removes the need to loop through all fds looking for the right one. And, with the message FD also passed along, it's now completely unnecessary to even pass fds to poll_rest() at all.

201977983e glib/gpoll W32: pass along GPollFD ptr for msg
Instead of just indicating that messages should be polled for, save the pointer to GPollFD that contains G_WIN32_MSG_HANDLE, and pass it along. This way it won't be necessary to loop through all fds later on, searching for G_WIN32_MSG_HANDLE.

cb2316aaa1 glib/gpoll W32: use WFSOE() instead of SleepEx()
WaitForSingleObjectEx() is supposed to be a more efficient sleep method.
It waits on the handle of the current process. That handle will be signaled once the process terminates, and since we're *inside* the process, it'll never happen (and if it does, we won't care anymore).
The use of an alertable wait ensures that we wake up when a completion routine wants to run.

d67b58a9a6 glib/gpoll: Remove if conditional
The original ready < nhandles - 1 can be re-written as ready + 1 < nhandles
which is the same confition that we are checking on the first
itteration of the for loop. This means we can remove the if statement
and let the for loop check the code.

This also has the side effect of removing an invalid check as
WAIT_OBJECT_0 was not subtracted from ready in the if statement.

b3e3ed7386 gmain: don't pass the same fd to g_poll() multiple times
If a given fd is being polled by multiple sources, we used to pass it
multiple times to g_poll(), which is technically illegal (and not
supported by the select()-based fallback implementation of poll() in
gpoll.c), and also made it more likely that we'd exceed the maximum
number of pollfds.

Fix it to merge together "duplicate" GPollFDs. The easiest way to do
this involves re-sorting context->poll_records into fd order rather
than priority order. This means we now have to walk the entire pollrec
list for every g_main_context_query() and g_main_context_poll(),
rather than only walking the list up to the current max_priority.
However, this will only have a noticeable effect if you have tons of
GPollFDs, and we're already too slow in that case anyway because of
other O(n) operations that happen too often. So this shouldn't change
much (and the new poll API will eventually let us be cleverer).

Remove some win32-specific code which did the same thing (but was
O(n^2)).

158dde0507 Replace #ifdef HAVE_UNISTD_H checks with #ifdef G_OS_UNIX
In Windows development environments that have it, <unistd.h> is mostly
just a wrapper around several other native headers (in particular,
<io.h>, which contains read(), close(), etc, and <process.h>, which
contains getpid()). But given that some Windows dev environments don't
have <unistd.h>, everything that uses those functions on Windows
already needed to include the correct Windows header as well, and so
there is never any point to including <unistd.h> on Windows.

Also, remove some <unistd.h> includes (and a few others) that were
unnecessary even on unix.

7f5b2901cf Remove alleged support for last-millennium Unixes
Remove workarounds for NeXTStep (last released in 1995), SunOS (1994),
HP-UX 9.x (1992) and 10.x (1995), OSF/1 / Digital UNIX / Tru64 UNIX
4.x (1999), and AIX 4.x (1999).

HP-UX 11 implements dlopen(), so dropping support for earlier versions
also lets us remove the HP-UX-specific gmodule-dld.

51a917bc16 Remove alleged support for BeOS
Since the initial addition of BeOS support in 1999, there has only
been one update to it (in 2005, and it wasn't even very big). GLib is
known to not currently build on Haiku (or presumably actual BeOS)
without additional patching, and the fact that there isn't a single
G_OS_BEOS check in gio/ is suspicious.

Additionally, other than the GModule implementation, all of the
existing G_OS_BEOS checks are either (a) "G_OS_UNIX || G_OS_BEOS", or
(b) random minor POSIXy tweaks (include this header file rather than
that one, etc), suggesting that if we were going to support Haiku, it
would probably be simpler to treat it as a special kind of G_OS_UNIX
(as we do with Mac OS X) rather than as its own completely different
thing.

So, kill G_OS_BEOS.
