Annotations missing after detach and enabled once breakpoints

[Xavier de Gaye]

I am implementing a GDB interface to Vim (VIM - Vi IMproved) that uses
GDB annotations level 2.

a) When a breakpoint is 'enable once', it becomes disabled the next
time it is hit. GDB does not send a 'breakpoints-invalid' annotation
in this case to annotate the change (but it rightly does when the
breakpoint's 'commands' are changed, for example).
See test case below.

b) After a detach command, GDB does not send a 'frames-invalid'
annotation. See test case below.

=========================================================================
/* The foobar program */
main()
{
    int i;

    for (i = 0; ; i++)
    {
    printf("value %d\n", i);
    usleep(500000);     /* 500 msecs */
    }
}

=========================================================================
# Testing  for 'breakpoints-invalid' annotation after 'enable once'
# has been hit
file foobar
break foobar.c:8
break foobar.c:9
enable once 2
run

# Stopped at breakpoint 1
# continue till stopped at enabled once breakpoint 2
set annotate 2
continue
quit
