Port the UT_LIST changes from InnoDB 8.x about embedded-innodb

Porting the current implementation should be fine right? https://github.com/mysql/mysql-server/blob/trunk/storage/innobase/include/ut0lst.h

Tried porting the above file, only sync0sync.h is giving trouble. Otherwise things look fine. I will try fixing it.

If you want I can help fix the sync0sync.h issue. Please post the problem here. I'm going to be busy for a week or so due to traveling. Expect late replies etc.

Checked in the clang-format file too.

I merged your code with main with some fixes and created a branch ut_list. You can rebase off that. Removed the noise. Should be easier to figure out the underlying issue.

I fixed the bug that was causing ib_ddl to fail. I think it's in the ut0lst.h code. Not in your change.

Draft PR with changes: https://github.com/RahulKushwaha/embedded-innodb/pull/2/files#
Build is successful, but failing tests. I think I mis-wired some of the variables.

Assertion in file trx0trx.cc is failing: ut_ad(UT_LIST_GET_LEN(trx->trx_locks) == 0);
Seems like when we try to release the locks via lock_release_off_kernel it does not work. lock_table_dequeue is not able to iterate on all the locks.
I will keep working on this.

Secondly, do you mind checking-in the clang-format file?

Thanks. I've transferred the ownership to my personal account. In case you have problems rebasing.

Working on the ut_list branch. tests crashing in method pars_resolve_exp_variables_and_types. it is not able to resolve the sym. Problem with list i guess. I will dig more.
