445373d028 x11: Check for XCB reply
Now that mutter can survive Xwayland vanishing in mid-flight, we need to
actually check if the Xserver reply fetched though XCB is not NULL,
otherwise we may crash, that would be a shame.

313e3e771c Make meta_* logging utilities not require line break
Unlike g_* logging utilities, the meta_* counterparts behave like odd
printf() functions. Lets change that so they fit better into how logging
is done everywhere else.

8e510a07c4 xprops: Use g_new0 instead of malloc in size_hints_from_results()
Switch the memory allocation in size_hints_from_results from a malloc call
without error-checking to g_new0 and adjust the free path accordingly.

e153524748 xprops: Use g_strdup in class_hint_from_results()
Use g_strdup instead of malloc + strcpy, this also gets rid of a bunch
of error checking which is no longer necessary, also adjust the free
path accordingly.

Note that there was a malloc + XFree mismatch in the removed error-handling.

89cd9d382d xprops: Use g_free instead of XFree in text_property_from_results()
results->prop is g_malloc memory so it should be free-ed with g_free not
XFree. The same applies to the return value of text_property_from_results
itself.

488991b0f6 xprops: Free counter_list_from_results() return value with g_free()
counter_list_from_results directly passes through the results->prop
pointer which is g_malloc memory, so we should free the buffer it
returns with g_free.

e2330617ac xprops: Free latin1/utf8_string_from_results() return value with g_free()
latin1_string_from_results and utf8_string_from_results use g_strndup,
so the returned string should be freed with g_free, rather then with
free or XFree. This fixes all free-s of buffers returned by these 2
functions to properly use g_free.

5e6d98e79f xprops: Use g_new0 instead of calloc in meta_prop_get_motif_hints()
Use g_new0 instead of calloc for motif_hints_from_results and adjust
its callers to use g_free.

Note that in the process_request_frame_extents function this replaces
the wrong original mismatch of calloc + XFree with a matching g_malloc +
g_free pair.

2f4a68c8c3 Clean up include macros mess
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.

76abe87090 xprops: Make sure text_property_to_utf8() returns UTF8
Commit 840378ae68 changed the code to use XmbTextPropertyToTextList()
instead of gdk_text_property_to_utf8_list_for_display(), but didn't
take into account that the replacement returns text in the current
locale's encoding, while any callers (rightfully) expect UTF8.

Fix this by converting the text if necessary.

dacc041d0c Switch meta_error_trap functions to MetaX11Display
They are X11 specific functions, used for X11 code. They have been
improved per jadahl's suggestion to use gdk_x11_lookup_xdisplay and
gdk_x11_display_error_trap_* functions, instead of current code.

5ba38a4ab6 x11/xprops: Plug a few memory leaks
Commits 6dbec6f8, 734402e1 and f041b35b introduced memory leaks by
switching to returning copies instead of the original buffers but
forgetting to free those original buffers.

Some error cases were also not freeing the ->prop buffer as they
should.

a7a376ae1f xprops: Null-terminate property reply values
Some of the mutter code using these properties expects them to be
null-terminated whereas xcb does not use null-terminated strings:

http://xcb.freedesktop.org/XcbRationale/

This was in some cases resulting in the WM_CLASS property containing
garbage data which broke application matching, caused the hot-corner and
window-switcher to stop working, or was exposed as text in the UI.

54557f062e xprops: Fix reading Window and XSyncCounter properties
Both Window and XSyncCounter are XIDs which on 64 bit X clients are 8
bytes wide. But the values on the wire are 32 bit so, for these types,
we always copy 4 bytes into results->prop. As such copying them out
with a cast such as *(Window *) means that we are actually reading 8
bytes which depending on whether the higher addressed 4 bytes are zero
means that sometimes this works while others it gives us a bogus
value.

bbf2b4e60e xprops: Don't pass ULONG_MAX as a uint32_t parameter
It seems the largest possible value is to be passed, so actually pass
that instead. Note that even though the name of the xcb_get_property
parameter is called 'long_length' its actually a uint32_t.

8f151842fb Start moving X11 implementation to its own subdirectory
This is specifically about managing X11 windows, not necessarily
running as an X11 compositor. By that I mean that this code is
still used for XWayland windows, and event handling is still and
modesetting / monitor management is still in core/.

This is also a fairly conservative move. We don't move anything
like screen.c or bell.c in here, even though those are really
only for X11 clients.
