**[WIP] multiple issue fixes for varchar column and complex columns that
grows more than 2MB
Fixed:
1. varchar data length is more than 2MB, buffer overflow exception (thread
local row buffer)
2. read data from carbon file having one row of varchar data with 150 MB
length is very slow.
TODO:
3. Jvm crash when data size is more than 128 MB in unsafe sort step.
4. analyze and remove min, max for varchar columns
5. check and restricting size of varchar columns.**
