[GSoC 2021] Socket Library

[PR by @king-11 as part of GSoC 2021. Reviewed by @mppf and @e-kayrakli ]

This PR adds an implementation of the Socket library to modules/packages.

This first version has some caveats:

  • requires libevent 2.1 or newer
  • requires CHPL_TASKS=qthreads right now (fifo doesn't work yet)
  • requires the C backend right now (CHPL_TARGET_COMPILER=llvm doesn't work yet)
  • requires libevent be available in /usr/include/event2

Design

#17899

Future Work

  • DNS Resolution using libevent

  • IO Plugin using libevent for non-blocking IO

  • sendAll method for UDP and TCP on lines of python's sendAll

  • Make work with LLVM and FIFO

  • Separate Module for Libevent
