#5702 Disable C++ exceptions

[Jonas Hahnfeld]

Disable C++ exceptions

1) Drop exception handling around scm_boot_guile

Doing this at the end of main() is pointless.

2) Disable exception handling code

We don't throw in LilyPond and it's only bloating the executable:
before: 192,586,512B
after: 166,845,952B (-13.3%)

This might also have a positive effect on the build time as well as
performance during runtime, but I didn't try to measure that for now.

Passes make, make check and a full make doc.

Leaving on review as this seems to be still under much discussion.

I think this can be moved to 'Patch on countdown for Feb 2nd' but can you check the Rietveld as I don't know if the last comment is enough to hold up the patch (either for change or more discussion).

As far as I understand, the consensus was that we don't need and don't want to use exceptions right now.
