Subject: [PATCH] Restore correct size of reserved data

A previous commit

  commit 7a9271620c894931cc22d6587d58e46c5996dac3

    Add support for LED state extension to gvnc

removed 4 elements from the reserved data field, when adding
one pointer. This is because it mistakenly thought the reserved
elements were 1 byte in length, when they are in fact one pointer
in size.

The original change was technically an ABI incompatible change,
as is this fix. In practice, however, GObject classes are never
instantiated statically at compile time. Instead a call to
g_type_register_static is made at runtime. So this change in the
class size won't have a negative effect unless someone has
subclassed the VncConnectionClass type. Even if subclassing, this
should be harmless as we've merely increased the memory allocation
by 3 words.
