Update (internal) list of breakpoints when creating / modifying / deleting using MI commands
This commit correctly updates internal breakpoint list when
breakpoints are manipulated through MI. In that case, GDB does not
generate breakpoint events, so this commit adds command post-execute
hook that injects an artifical breakpoint event back onto an event
queue.

The `-break-condition' Command
------------------------------
Synopsis
........
-break-condition NUMBER EXPR
Breakpoint NUMBER will stop the program only if the condition in
EXPR is true. The condition becomes part of the `-break-list' output
(see the description of the `-break-list' command below).
{No value for `GDBN'} Command
.............................
The corresponding {No value for `GDBN'} command is `condition'.
Example
.......
(gdb)
-break-condition 1 1
^done
(gdb)
-break-list
^done,BreakpointTable={nr_rows='1',nr_cols='6',
hdr=[{width='3',alignment='-1',col_name='number',colhdr='Num'},
{width='14',alignment='-1',col_name='type',colhdr='Type'},
{width='4',alignment='-1',col_name='disp',colhdr='Disp'},
{width='3',alignment='-1',col_name='enabled',colhdr='Enb'},
{width='10',alignment='-1',col_name='addr',colhdr='Address'},
{width='40',alignment='2',col_name='what',colhdr='What'}],
body=[bkpt={number='1',type='breakpoint',disp='keep',enabled='y',
addr='0x000100d0',func='main',file='hello.c',fullname='/home/foo/hello.c',
line='5',cond='1',thread-groups=['i1'],times='0',ignore='3'}]}
