Refactoring the Code to Adhere to Clean Code Principles on src/connector.c

[BrunoRiibeiro]

• The start_connector function has been divided into smaller functions with single responsibilities:

  • initialize_connector: Sets up the environment and initialises the epoll.
  • handle_write_event: Handles write events.
  • handle_read_event: Handles read events.

• Replaced magic numbers with named constants (BUFFER_SIZE, MESSAGE_SIZE, EPOLL_MAX_EVENTS).

• Improved error handling with more descriptive messages.

• Ensured consistent resource management with rigorous checks for memory allocation and release.

• Updated variable and function names to be more descriptive, enhancing clarity and code maintainability.
