the structure produced has alignment, which contained uninitialized data.

This is obviously fixed by using calloc(), but it was also observed that the precalculated storage requirement was higher than what is actually filled. So all the math has been rewritten to be byte accurate. Temporarily, a syslog_r check is added to report if we ever get count inconsistancy again so that can be fixed quickly. ok claudio

A few sys/param.h annotations lacked ALIGNBYTES

Correctly jump over routing headers and calculate the size of the if_data

struct in the if_msghdr instead of using sizeof() blindly. This allows us to grow if_data without causing issues for the getifaddrs() users. OK deraadt@ (who needs this for some cool upcomming stuff)

remove obsolete comment, no SIOCGIFCONF path any more
