Manuel Pégourié-Gonnard c4a47e3483 Fix bug checking pathlen on first intermediate
Remove check on the pathLenConstraint value when looking for a parent to the
EE cert, as the constraint is on the number of intermediate certs below the
parent, and that number is always 0 at that point, so the constraint is always
satisfied.

The check was actually off-by-one, which caused valid chains to be rejected
under the following conditions:
- the parent certificate is not a trusted root, and
- it has pathLenConstraint == 0 (max_pathlen == 1 in our representation)

fixes #280

Manuel Pégourié-Gonnard 215a14bf29 Fix potential heap corruption on Windows
If len is large enough, when cast to an int it will be negative and then the
test if( len > MAX_PATH - 3 ) will not behave as expected.

Manuel Pégourié-Gonnard 1c38550bbd Skip to trusted certs early in the chain
This helps in the case where an intermediate certificate is directly trusted.
In that case we want to ignore what comes after it in the chain, not only for
performance but also to avoid false negatives (eg an old root being no longer
trusted while the newer intermediate is directly trusted).

see #220

Nicholas Wilson bc07c3a1f0 fix minor bug in path_cnt checks
If the top certificate occurs twice in trust_ca (for example) it would
not be good for the second instance to be checked with check_path_cnt
reduced twice!
