WIP kinfo_file/kinfo_vmmentry tweaks. The idea:

1) to get the 32 and 64 bit versions in sync so that no shims are needed,
Valgrind in particular excercises this.  and:
2) reduce the size of the copyout.  On large processes this turns out to
be a huge problem.  Valgrind also suffers from this since it needs to do
this in a context that can't malloc. I want to pack the records.
3) Add new types..  'tell me about fd N' and 'tell me about addr N'.
