* Impl bne

  * Add base64 upload method
  * Remove pollin_f()
  * Caller should terminate cmdline
  * Newline style detection for \r\n, \r\0, \r or \n
  * Issue "enable", "system" and "shell" on set up
  *
* Rename prne_strnstr() -> prne_memmem()
* Added prne_rebuild_str() for efficiency
* Daemonise proone so that bne can clean up after upload
