This PR implements epoll system calls for TCP sockets. AFAIK, this implementation covers essential features needed for running Node.js applications. Closes #19

Run Kubernetes pods in Kerla

Namely, write documentation and implement missing features to make following manifest work: ```yaml apiVersion: v1 kind: Pod metadata: name: nginx spec: runtimeClassName: kerla containers: - name: nginx image: nginx ```...

Compress symbol table

Currently, a symbol table reserves 2MiB space to store symbols (e.g. function names) of the kernel. Because symbols in Rust tend to be lengthy, they are truncated to 55 characters....

In smoltcp, the Kerla's TCP/IP implementation, there're some `O(|# of sockets|)` loops and it would lead to a scalability issue in the future: https://github.com/smoltcp-rs/smoltcp/blob/8e6fc7fec85188a783ed80a25ee2159201aa74e8/src/iface/interface.rs#L2019 The priority is not that high,...

IIUC it's essential to run event-driven programs like Node.js.
