[PATCH v2 00/10] Coverity fixes for vchan-socket-proxy

[Jason Andryuk <jandryuk@gmail.com>]

This series addresses some Coverity reports.  To handle closing FDs, a
state struct is introduced to track FDs closed in both main() and
data_loop().

v2 changes "Ensure UNIX path NUL terminated" to avoid a warning with
gcc-10.  Also, "Move perror() into listen_socket" and "Move perror()
into connect_socket" are new.

Jason Andryuk (10):
  vchan-socket-proxy: Ensure UNIX path NUL terminated
  vchan-socket-proxy: Move perror() into listen_socket
  vchan-socket-proxy: Move perror() into connect_socket
  vchan-socket-proxy: Check xs_watch return value
  vchan-socket-proxy: Unify main return value
  vchan-socket-proxy: Use a struct to store state
  vchan-socket-proxy: Switch data_loop() to take state
  vchan-socket-proxy: Set closed FDs to -1
  vchan-socket-proxy: Cleanup resources on exit
  vchan-socket-proxy: Handle closing shared input/output_fd
