tools: add skeleton code for userland testing of VMA logicEstablish a new userland VMA unit testing implementation undertools/testing which utilises existing logic providing maple tree supportin userland utilising the now-shared code previously exclusive to radixtree testing.This provides fundamental VMA operations whose API is defined in mm/vma.h,while stubbing out superfluous functionality.This exists as a proof-of-concept, with the test implementation functionaland sufficient to allow userland compilation of vma.c, but containing onlycursory tests to demonstrate basic functionality.Link: https://lkml.kernel.org/r/533ffa2eec771cbe6b387dd049a7f128a53eb616.1722251717.git.lorenzo.stoakes@oracle.comSigned-off-by: Lorenzo Stoakes Tested-by: SeongJae Park Acked-by: Vlastimil Babka Reviewed-by: Liam R.
