memory handles with status 'local data' and status 'for networking'

[divanchykhin]

Currently we, by-fact, have only the second type which assumes reading by parsers and writing consecutively and somehow formatted, or, at least, ordered (to be parsed then); respectively, request and response parts make sense, etc. Data organized in this way is good for sending over network.
The other possible type is for storing/reading local data (for instance, locally defined structures). In this case reading/writing data between local buffers (such as structure on stack) and memory behind a handle is a typical operation; respectively, memory behind a handle is considered as just one block.
Despite internals operations over handles of the above two different types are different, and handles must have an indicator 9a flag) to which type they are related (with respective checks, etc)
