osdep: Fix runtime failure on older Linux kernels
If QEMU finds newer kernel header files on compilation time, it will use
advertised features like pipe2 or SOCK_CLOEXEC by just doing a compile test.
If later the executables are executed on an older kernel (<2.6.27,
like Xen Dom0 2.6.18), then QEMU will fail on opening sockets and creating
pipes and returns the rather unspecific "qemu_init_main_loop failed".

vnc: fix capslock tracking logic.
The capslock tracking logic added by commit
6b1325029d80455b9da7cd7bd84a88cb915b867c doesn't work correctly for vnc
clients without EXT_KEY_EVENT support. The reason is that qemu converts
keysyms for letters to lowercase for the keysym2scancode lookup. It
then also passes the lowercase value down to do_key_event(), but the
capslock tracking code needs it with the correct case to work properly.
This patch adds a new variable for the lowercase keysym so we'll keep
the unmodified value for do_key_event().
The keysym2scancode is not needed with EXT_KEY_EVENT capable clients
like any app based on the gtk-vnc widget, so I missed that case in
testing ...
