This patchset clean-up the migration target allocation functions.

* Changes on v3
- do not introduce alloc_control for hugetlb functions
- do not change the signature of migrate_pages()
- rename alloc_control to migration_target_control

* Changes on v2
- add acked-by tags
- fix missing compound_head() call for patch #3
- remove thisnode field on alloc_control and use __GFP_THISNODE directly
- fix missing __gfp_mask setup for patch
"mm/hugetlb: do not modify user provided gfp_mask"

* Cover-letter

Contributions of this patchset are:
1. unify two hugetlb alloc functions. As a result, one is remained.
2. make one external hugetlb alloc function to internal one.
3. unify three functions for migration target allocation.

The patchset is based on next-20200621.
