[PATCH 1/6] Add a field 'installed' for each location of tracepoint.

[Yao Qi <yao@codesourcery.com>]

Hi, this patch adds a field 'installed' indicating whether a
location of tracepoint is installed on target.  In CLI, the output of
'info tracepoint' will be like this,

info trace
Num     Type           Disp Enb Address    What^M
2       tracepoint     keep y   0x080485b1 in main at gdb.trace/change-loc.c:29
        installed y
4       tracepoint     keep y   <MULTIPLE>
        collect $eip
4.1                         y     0x0804859c in func4 at gdb.trace/change-loc.h:35
        installed y
4.2                         y     0xb7ffc480 in func4 at gdb.trace/change-loc.h:35
        installed y

Of course, the breakpoint related MI notifications are changed as
well.
