Log Message:
PR/10266: Jason R. Thorpe: curses programs totally broken.
Re-write t_agetstr() so that it does not use realloc so userland
programs don't break. We now use an internal buffer to keep track
of the memory we allocate. This changes the api of t_agetstr() to
take 2 fewer arguments, but there are not many programs that use it.
Please note that this does not change binary compatibility with the
previous t_agetstr() since the usage was:

        char *area, *p;

        *area = NULL;
        t_agetstr(ti, "ic", &area, &p);
        ...
        free(area);

Since we don't touch the arguments and free(NULL) is a no-op, nothing
breaks.

Since we don't break binary compatibility there is no reason to bump
the library's major number, but since we change t_agetstr() I'll bump
the minor number for good measure.
