Subject: r3126: in the brlock code I had used a void* for the brl context as I
 didn't want to expose the brl context structure outside the brlock.c code.
 Instead, I now use "struct brl_context *" and rely on C being happy to pass
 around pointers to unknown structures as long as they are not dereferenced. I
 will be interested to see how the build farm likes this. (This used to be
 commit cb155c8ad837285c5a7f5b104968239df0b65fd2)
