[PATCH v5 0/2] MR5047: server, ntdll: Use 64 bit for unix thread id.
This is in preparation for the mach thread id rework, which requires 64 bit there (and incidentally also stops truncating the FreeBSD one). There wasn't any direct usage of `__int64` in the sever protocol before, so I added a new typedef and a new `dump_int64()` function (not sure if needed per se though). -- v5: ntdll: Remove unneeded FreeBSD codepath in get_unix_tid(). server, ntdll: Use 64 bit for unix thread id. https://gitlab.winehq.org/wine/wine/-/merge_requests/5047
