zhoumeina

Tue Jan 7 04:45:06 UTC 2014
v3-v4 restructure js code to drop redundance code.
replace tabs with 4 spaces
v2-v3 Add related make files
v1-v2 add spice.html.tmpl
This patch add the front end support of spice.
1 If there were a spice vm in host, show a "spice" button
but not "vnc" in guest page.
2 click "spice" we can show a screen just like the demo

+ * NOTE: The AT/MF keyboards can generate (via the 8042) two (MF: three)
+ * sets of scancodes. Set3 can only be generated by a MF keyboard.
+ * Set2 sends a makecode for keypress, and the same code prefixed by a
+ * F0 for keyrelease. This is a little bit ugly to handle. Thus we use
+ * here for X386 the PC/XT compatible Set1. This set uses 8bit scancodes.
+ * Bit 7 ist set if the key is released. The code E0 switches to a
+ * different meaning to add the new MF cursorkeys, while not breaking old
+ * applications. E1 is another special prefix. Since I assume that there
+ * will be further versions of PC/XT scancode compatible keyboards, we
+ * may be in trouble one day.
+ *
+ * IDEA: 1) Use Set2 on AT84 keyboards and translate it to MF Set3.
+ * 2) Use the keyboards native set and translate it to common keysyms.
