Description

Most of the functions in Gandiva's Python Expression builder interface current accept None in their arguments, but will segfault once they are used.

Example:

import pyarrow
import pyarrow.gandiva as gandiva

builder = gandiva.TreeExprBuilder()
field = pyarrow.field('whatever', type=pyarrow.date64())
date_col = builder.make_field(field)

func = builder.make_function('less_than_or_equal_to', [date_col, None], pyarrow.bool_())

condition = builder.make_condition(func)

# Will segfault on this line:
gandiva.make_filter(pyarrow.schema([field]), condition)

I think this is just a matter of adding not None to the appropriate function arguments.
