Store extra zone data separately.

Browse Source 
Extra zone data consists of:
- custom zone name,
- zone text,
- zone callstack index.

If neither of these data values is stored in zone, 5 bytes are saved. If
any one of them is required, extra 4 bytes are added, for an index into
extra data array.

Memory savings:

android         2371 MB -> 2324 MB
big             7593 MB -> 6747 MB
