Inspired by U-Boot's addition of the ufetch command and the neofetch utility for Linux, add a similar command to barebox.
The command is meant to fancily show off a barebox port with some colored ASCII art. The usual alternative is a screenshot of a barebox boot up and prompt, which doesn't look fancy, because a first port nearly always contains some warning/error messages (e.g. because there is no bootsource available and net boot is unconfigured). Example: https://raw.githubusercontent.com/a3f/a3f.github.io/refs/heads/master/img/bfetch.png This series also includes an abnormal amount of Yakshaving. Understandably, we need to export a lot of helpers and lists for bfetch to be able to enumerate what features are available at runtime. For some things like what CPU we are running on, what uptime we have or what's the TEE's implementation ID, we readily have code that prints to stdout, but it is not reusable because we do not buffer console output streams and thus no command output capture or piping support. But even if we had piping, we would need to manipulate strings to split lines into key/value pairs. Instead, let's rethink the problem: We have commands like cpuinfo, which format a table with key/value pairs and print it to out. Then the UNIX way would be to use awk/grep/sed/perl or whatever to separate them out again. Why not skip that and have commands directly return an object with key/value pairs (attributes) or more complex data structures like PowerShell is able to do? This series does exactly that. Device parameters are now associated with a struct bobject and that bobject can be returned and consumed by commands without requiring association with a device. This mechanism should be able to bring support for the pipe operator to barebox' shell once the critical commands are adapted to use it and there exists a way for commands to report whether they support structured I/O or not. As I am still figuring out how to do that, I did not include a command that captures structured output to a variable, but that would follow in future.
