style: [patch 1/22] use /r/3648/ to reorganize includes

ruby: eliminate type uint64 and int64
These types are being replaced with uint64_t and int64_t.

ruby: reverts to changeset: bf82f1f7b040

ruby: slicc: use default argument value
Before this patch, while one could declare / define a function with default
argument values, but the actual function call would require one to specify
all the arguments. This patch changes the check for function arguments.
Now a function call needs to specify arguments that are at least as much as
those with default values and at most the total number of arguments taken
as input by the function.

ruby: initialize replacement policies with their own simobjs

this is in preparation for other replacement policies that take additional
parameters.
