Issue 4988 straight-flags partly wrong calculated

The angles for straight-flags at down- and up-pointing stems are now
accurately respected.
This will cause some slight changes in the reg-tests.
Also fixing flat-flags, which relied on the old, buggy calculation.
Also doing the same fixes for markup-command note-by-number.
Also fixing an oversight in regtest metronome-mark-formatter.ly,
where the creation of the metronome-markup depends on note-by-number.

In scheme-generated flags the calculation done in straight-flag is partly wrong. Causing the used angle to come out different for down-stem flags.

It's hard to see (thanks to Malte), thus I added long lines to the beam in a wide paper setting and attached an image with current state.

Using this basic code

\version "2.19.49"
{
  \time 1/8

  \override Flag.stencil = #(straight-flag 0.5 1   1 10   1 10)

  \autoBeamOff

  \stemUp c''16 
  \stemDown c''
}

with a wide custom-paper-size
