[PATCH] server: zero allocated memory after allocating mappings

[Jefferson Carpenter]

See attached patch for one way to fix this.  A macro is used to
iterate over all of the struct's members, and it is used both to
define the struct, and to pack it into a BLOB (and to un-pack it (not
shown)).  Patch not suggested for merge.

Is this the kind of thing you're interested in?
