lots of misc connection refactoring / fixes:
* adds blocklogger as a way to writing logging information from the backend directly to the a terminal block
* use blocklogger in conncontroller
* use blocklogger in sshclient
* fix remote name in password prompt
* use sh -c to get around shell weirdness
* remove cmd.exe special cases
* use GetWatcher().GetFullConfig() rather than re-reading the config file
* change order of things we do when establishing a connection. ask for wsh up front. then do domain socket, then connserver
* reduce number of sessions required in the common case when wsh is already installed. running the connserver is now a "multi-command" which checks if it is installed, then asks for the version
* send jwt token over stdin instead of in initial command string
* fix focus bug for frontend conn modal
* track more information in connstatus
* simplify wshinstall function
* add nowshreason
* other misc cleanup
* use pwsh over powershell if installed (on windows) for default shell
* refactor blockcontroller.DoRunShellCommand into a "setup" and "manage" phase
* fix wshcmd-conn to also disconnect wsl connections
* new genconn interfaces to make a standardized environment to run SSH/WSL commands via `sh -c`. also create better quoting functions that are composable
* replace html/template with text/template for shell command templating (avoids special chars getting turned into HTML entities, breaking the commands)
* do not reinstall wsh if the installed version has a higher version (prevents flip-flopping on shared systems)
* simplify clientOs/clientArch detection. use `uname -sm`. also validate the os/arch combo as compatible with our builds.
* replace CpHostToRemote with CpWshToRemote. hard codes wsh paths inside of the function instead of having them passed in (quoting restrictions)
* new SyncBuffer class to use with commands that properly synchronizes Writes/String output
* fix setTermSize to actually update DB with terminal size
The wsl largely ignores most nowsh stuff, but there are some options
that can be specified for wsl. This ensures that it will still work
whether or not they are set.
Additionally if fixes the wsh not installed icon.
implements `wsh run` command. lots of fixes (and new options) for command blocks. cleans up the UX/UI for command blocks. lots of bug fixes for blockcontrollers. other minor bug fixes.
also makes editor:* vars into settings override atoms.
