Update metalinter, fix a few lint warnings and replace deprecated linters.
`deadcode`, `structcheck` and `varcheck` are abandoned and now replaced by [`unused`][1].
Since 1.19, `go fmt` reformats godocs according to https://go.dev/doc/comment. I've done a bulk-reformatting of the codebase to keep the linter happy. Backporting is mostly harmless (the exception being `lib/services/role_test.go`, that for some reason breaks the _old_ linter using the new format).

* Fix bodyclose on lib/kube/proxy/streamproto/proto_test.go
* Fix bodyclose on lib/srv/alpnproxy/proxy_test.go
* Fix bodyclose on lib/web/conn_upgrade_test.go
* Silence staticcheck on lib/kube/proxy/forwarder_test.go
* Silence staticcheck on lib/utils/certs_test.go
* Address BuildNameToCertificate deprecation warnings
* Run `go fmt ./...`
* Run `go fmt ./...` on api/
* Ignore formatting in role_test.go
* Remove redundant initializers in lib/srv/uacc/
* Update e/
Use a buffered channel pipe to increase the speed of windows stdin closer to real-time. The speed increase makes it so that VT sequences are captured properly by windows.
This change clears the screen when an ssh session ends (only in FIPS mode). Note: This doesn't currently do anything in `tsh` on Windows since BoringCrypto isn't supported, but once it is supported, the behavior will match Unix and web.

* Add support for `tsh ssh` on Windows
This adds Windows session support to tsh, taking advantage of ANSI
terminal support and VT emulation added in recent versions Windows
10. On supported Windows versions (Windows 10 1607+), `tsh ssh`
should work as expected in `cmd.exe`, PowerShell, and the new
Windows Terminal app.
* Address a few review comments
* Remove significant chunks of unnecessary tncon code.
Removes the global buffer, `GetVTSeqFromKeyStroke`, and several
ancillary headers and functions that aren't needed for our (current)
use-case. Also removes mouse and focus events.
* Refactor OS-specific terminal handling
This significantly simplifies OS-specific terminal behavior:
* Move OS specific terminal code into a new `terminal` package
* Remove `session_windows.go` in favor of an OS-independent
`session.go`, defer to terminal package for OS specific
functionality.
* Remove ConPTY since it's not needed.
* Always wait for the terminal and ssh session to fully close before
quitting.
* Refactor tncon; ensure the raw reader can be closed and reopened,
remove lots of unnecessary C code.
* Revert dependency changes
* Use WindowsOS constant.
* Fix `tsh play` on Windows
This fixes `tsh play` on Windows by using the new `terminal` module to
initialize the terminal for raw input in a cross-platform way.
Additionally, this simplifies `terminal.New()` since in practice we never
want interactive mode at init time, and fixes a broken unit test.
* Use correct log library
* Fix `tsh play` player controls on Windows
This fixes the console player controls on Windows as well as the timestamp
writer.
* Clean up lints
* Add missing license header
* Fix broken unit test
* Fix cross-compile builds on Linux/Docker
We need windows.h, which is not capitalized in the mingw packages
(and is case insensitive on Windows).
* Address code review feedback
- Rename `Terminal.InitInteractive` to `Terminal.InitRaw`
- Ensure goroutines terminate on close
- Fix outdated godoc comments
- Ensure Terminal event subscribers are cleared (and their channels
are closed)
- Ensure terminal output mode is reset on error in initTerminal
- Bubble up errors in Terminal.Close()
- Add author notice to tncon.c re: our changes
- Add go-ansiterm as a direct dependency
- Run `make update-vendor`
* Add constants and a small player.go TODO.
* Clear linter warning
