bisect: move 'printresult' in the 'hbisect' module

The logic is already extracted into a closure. We move it into the module
dedicated to bisect.

A minor change is applied: the creation of the 'displayer' is kept in the main
command function, it remove the needs to import 'cmdutil' in 'hbisect'. This
would create an import circle otherwise.

    ui as uimod,

# ensure errors aren't buffered
testui = color.colorui()
testui.pushbuffer()
testui.write(('buffered\n'))
testui.warn(('warning\n'))
testui.write_err('error\n')
print(repr(testui.popbuffer()))

# test dispatch.dispatch with the same ui object
hgrc = open(os.environ["HGRCPATH"], 'w')
hgrc.write('[extensions]\n')
hgrc.write('color=\n')
hgrc.close()

ui_ = uimod.ui()
ui_.setconfig('ui', 'formatted', 'True')

# we're not interested in the output, so write that to devnull
ui_.fout = open(os.devnull, 'w')

# call some arbitrary command just so we go through
# color's wrapped _runcommand twice.

    dispatch.dispatch(dispatch.request(['version', '-q'], ui_))

runcmd()
