cargo update

[extrawurst]

updating a few major dependencies is blocked right now by the ecosystem taking its time to follow the new major versions of syn and bitflags. and minor versions of regex-syntax, redox_syscall.

syn

as it seems we have to wait for a few remaining crates to release new versions:

• struct-patch-derive (using old syn): syn2 release? yanganto/struct-patch#19
  • it uses proc-macro-error which has no support for syn2 merged&released yet: https://gitlab.com/CreepySkeleton/proc-macro-error/-/merge_requests/36
• bugreport which in turn requires git-version (using old syn): Update syn to 2.0 fusion-engineering/rust-git-version#20
  • or alternatively: remove unmaintained git-version dependency? sharkdp/bugreport#13
• chrono -> iana-time-zone -> iana-time-zone-haiku (v0.1.1) which still depends transitively on syn1 via cxx-build: bump haiku dependency strawlab/iana-time-zone#110

regex-syntax ✅

• syntect (using old regex-syntax): release with bumped regex-syntax trishume/syntect#486

redox_syscall

• shellexpand in turn using redox_users used by (using old redox_syscall): https://gitlab.redox-os.org/redox-os/users/-/merge_requests/36
• notify using filetime (redox_syscall): release version bumping the redox_syscall dependency alexcrichton/filetime#98
  • bump in notify: bump filetime dependency notify-rs/notify#521
  • new notify release: release with bumped bitflags and filetime version notify-rs/notify#513

bitflags

• ron (bitflags): new release bumping bitflags dependency ron-rs/ron#469
• notify (bitflags): release with bumped bitflags and filetime version notify-rs/notify#513
• crossterm (bitflags): release with bumped bitflags dependency crossterm-rs/crossterm#807
• git2 (bitflags): release with bumped bitflags version rust-lang/git2-rs#976
• syntect: update bitflags trishume/syntect#490

help needed:

• redox_syscall itself does not support working with bitflags 2.x: redox_syscall (MR needed)

plus our very own:

• usage of dirs-next: switch back to dirs #1783

struct-patch-derive already use syn2 after 0.3.0 release

ok i will merge this now and add the two remaining exceptions to unblock a lot of other work. the two exceptions are bitflags and itertools
