One about a possible uninitialised variable (incorrect, but it's easier
to keep the compiler happy) and one warning about "const static" being
backwards.

This commit fixes a number of crashes caused by malloc failures. They
were found using the -malloc-test=0 option to runner.go which runs tests
many times, causing a different allocation call to fail in each case.

(This test only works on Linux and only looks for crashes caused by
allocation failures, not memory leaks or other errors.)

This is not the complete set of crashes! More can be found by collecting
core dumps from running with -malloc-test=0.

When a chain is complete and ends in a trusted root checks are also performed
on the TA and the callback notified with ok==1. For consistency do the same for
chains where the TA is not self signed.
