replace jsoncpp with yajl (thanks topfs2)

* topfs2/remove_jsoncpp: (21 commits)
  Fix. Added explicit typecast to platform int to quench warnings for variant use in jsonrpc
  [win32] replace jsoncpp with yajl
  Removed jsoncpp
  Added pragma and license to IClient.h
  Removed the dependency of jsoncpp in CVariant
  Switched to use CVariant instead of jsoncpp values in JSON-RPC
  Added yajl writer for Variant
  Added yajl parser for Variant
  Added c_str and have size of variant work with strings
  Added check for libyajl to configure
  Added CVariant::type which returns the type of the current variant (easier than multiple isFoo queries)
  Switched Variant to use double internally, still accepts floats
  Added swap method to CVariant
  Moved to use explicit type in CVariant instead of isFoo
  Added operator== to CVariant
  Added array and map iterators to CVariant
  Added CVariant constructor which takes a string pointer and length
  Added append to CVariant
  Added isMember to CVariant
  Removed debug in CVariant
