p2papp: p2p chat, file sharing and remote command execution.

a ~300 LOC single file C app without runtime deps other than libc.

no compile time deps other than gcc. even C headers not needed.

IP filtered singleton one-to-one connection. no socket backlog.

p2pchat: This is a clone/fork of p2papp  with only one difference:

remote command execution logic completely stripped of. So more safe.
