Copy a field part into an output buffer.
SYNOPSIS
Field::get_key_image()
buff [out] output buffer
length output buffer size
cs charset, always same as this->charset(),
(to be removed in 5.x)
type itMBR for geometry blobs, otherwise itRAW
DESCRIPTION
This function makes a copy of field part of size equal to or
less than "length" parameter value.
For fields of string types (CHAR, VARCHAR, TEXT) the rest of buffer
is padded by zero byte.
NOTES
For variable length character fields (i.e. UTF-8) the "length"
parameter means a number of output buffer bytes as if all field
characters have maximal possible size (mbmaxlen). In the other words,
"length" parameter is a number of characters multiplied by
field_charset->mbmaxlen.
RETURN
Number of copied bytes (excluding padded zero bytes -- see above).

/*
For ROLLUP queries each constant item referenced in GROUP BY list
is wrapped up into an Item_func object yielding the same value
as the constant item. The objects of the wrapper class are never
considered as constant items and besides they inherit all
properties of the Item_result_field class.
This wrapping allows us to ensure writing constant items
into temporary tables whenever the result of the ROLLUP
operation has to be written into a temporary table, e.g. when
ROLLUP is used together with DISTINCT in the SELECT list.
Usually when creating temporary tables for a intermidiate
result we do not include fields for constant expressions.
