Subject: Fix critical block logic
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;ds=sidebyside;h=ecd7af790bd3ab7c7e768f68968379e1feea56a9;hp=ecd7af790bd3ab7c7e768f68968379e1feea56a9;p=r2c2.git

Fix critical block logic

First noncritical block is not reliable, as it could be outside of the
train's allocated blocks and not guaranteed to set to a consistent path.
Worse, the get_first_noncritical_block function could return a block on
the other side of a turnout which is changing path, and is_block_critical
used completely different logic.
