This was the only place where we didn't use the exceptionCheck()
function. Besides being more consistent, it's also more verbose if an
exception occurs.

QNX: Fix build for QNX 6.5

QNX 6.5 does not have readdir64_r, which is selected by current
qplatformdefs.h. There is only a reentrant version (readdir_r) which
does not support large files and a large file version (readdir64) which
is not reentrant. The reentrant version (readdir_r) will be chosen now.

In summary, the following versions will be used:
QNX 6.5:  readdir_r    (postfix '_r': reentrant version)
QNX 6.6: _readdir_r    (prefix  '_' : extra stat info included)
BB 10:   _readdir64_r  (infix   '64': large file support)

Fix visual selection with EGL on xcb

Using a 24-bit visual for 8888 configs is wrong since we loose the
alpha channel. This breaks translucent windows and, among others,
leads to not showing drag pixmaps (that typically have transparent
areas) properly.

Fix alpha in no-opengl configuration on xcb

Like the EGL + xcb configuration, the -no-opengl is broken too when
it comes to translucent windows: Requesting an alpha channel is futile
since the xcb_create_window call always uses the root's depth and visual.

This is now corrected by picking a 32-bit visual.

This will make translucent windows and drag pixmaps appear correctly again.

iOS: delay callbacks to UITextInput to avoid recursion

If the application calls "reset" or "commit" on the input
method (or forces active focus on some other item) from a text
changed or key pressed handler, iOS will sometimes throw
an exception. It does so because we try to change the state
of UITextInput (by calling textDidChange) while processing a
callback from the same place (insertText).

Optimally this should not happen since we would normally
post such events to Qt, not send them directly. But with
text input we cannot do this since UITextInput expects us
to update immediately upon receiving text input callbacks.
If not, word completion and spell checking will stop working.

This change will guard against recursive callbacks by delaying
callbacks to UITextInput when text/selection/first responder
changes.
