[PATCH 06/23] libsupport: port the kernel list.h to libsupport

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

In the next patch, we're going to add the xfsprogs cache manager code to
e2fsprogs.  That code is going into libsupport so that it doesn't become
part of the libext2fs ABI, and it depends on a richer set of list_head
helpers than what is in kernel-list.h, so port the Linux 6.17 list.h to
libsupport and drop the one in libext2fs.

Signed-off-by: "Darrick J. Wong" <djwong@kernel.org>
