ARROW-1528: [GLib] Resolve recursive include dependency
Before:
* arrow-glib/field.h depends on arrow-glib/data-type.h
* arrow-glib/data-type.h depends on arrow-glib/field.h
After:
* arrow-glib/field.h depends on arrow-glib/basic-data-type.h
* arrow-glib/basic-data-type.h doesn't depend on arrow-glib/field.h
* arrow-glib/composite-data-type.h depends on
arrow-glib/basic-data-type.h and
arrow-glib/composite-data-type.h
Author: Kouhei Sutou <k...@clear-code.com>
Closes #1091 from kou/glib-resolve-recursive-dependency and squashes the
following commits:
