zhanghailiang 5bbebf6228 libcacard: fix resource leak
In function connect_to_qemu(), getaddrinfo() will allocate memory
that is stored into server, it should be freed by using freeaddrinfo()
before connect_to_qemu() return.

Michael Tokarev 2a0c46da96 vscclient: use glib thread primitives not qemu
Use glib-provided thread primitives in vscclient instead of
qemu ones, and do not use qemu sockets in there (open-code
call to WSAStartup() for windows to initialize things).

This way, vscclient becomes more stand-alone, independent on
qemu internals.

Michael Tokarev 1687a089f1 libcacard: remove useless initializers
libcacard has many functions which initializes local variables
at declaration time, which are always assigned some values later
(often right after declaration).  Clean up these initializers.

Stefan Weil 5ad04fb6f1 libcacard: Fix compilation for older versions of glib (bug #1258168)
See https://bugs.launchpad.net/bugs/1258168

libcacard/vscclient.c: In function 'do_socket_read':
libcacard/vscclient.c:410: warning: implicit declaration of function 'g_warn_if_reached'
libcacard/vscclient.c:410: warning: nested extern declaration of 'g_warn_if_reached'
libcacard/vscclient.c: In function 'main':
libcacard/vscclient.c:763: warning: implicit declaration of function 'g_byte_array_unref'
libcacard/vscclient.c:763: warning: nested extern declaration of 'g_byte_array_unref'
...
libcacard/vscclient.o: In function `do_socket_read':
libcacard/vscclient.c:410: undefined reference to `g_warn_if_reached'
libcacard/vscclient.o: In function `main':
libcacard/vscclient.c:763: undefined reference to `g_byte_array_unref'

g_warn_if_reached was added in glib 2.16, and g_byte_array_unref is
supported since glib 2.22. QEMU requires glib 2.12, so both names must
not be used.

Instead of showing a warning for code which should not be reached,
vscclient better stop running, so g_warn_if_reached is not useful for
vscclient.

In libcacard/vsclient.c, g_byte_array_unref can be replaced by
g_byte_array_free. This is not generally true, so adding a compatibility
layer in include/glib-compat.h is no option here.
