initial support for PTS index file generation

a new option (-i) to ./gen-patch-info.py allows for generating a global
"index" file with any and all information that the PTS might want from
this system.  The format is:

{
 "index-version": N
 "packages":
 {
   "<pkg1>":
   {
     "url": url-for-all-versions
     "versions":
     {
       "<vers1>":
       {
         <various attributes>
       }
     }
   }
 }
}

index-version is a monotonically increasing version number.  when the
"schema" changes, this version is incremented.  if we care enough, we
can do a major-minor versioning scheme where BC breaks are differentiated
from "new attribute" type changes by incrementing the major or minor
versions, respectively.
