> In DRILL-379, the code uses a wrapper buffer over a java byte array for temporary buffer
used by some string functions. However, such wrapper buffer will use big endian, different
from Drill's native little endian. This may not be a big issue for string, but could cause
serious issues for other types.  
> In stead, we should use an approach where the buffer is provided from Drill fragment
context through pseudo-injection to get the access to buffers, and the context will be responsible
for cleaning things up.
