Allow multiple read from IPC + some refactor

[cylian914]

The previous implementation was closing the connection right after 1 message (ligne 87) so i couldn't send multiple request with the same socket, this fix it.

[vaxerski]

that is intentional though.

[cylian914]

Why ?

[vaxerski]

reading more can block, besides, there is no point. Just open a new socket connection?

[cylian914]

How can it block ? the only thing that could happen is the client crash right after the data is send (so client doesn't read hyprpaper message) and in that case it crash hyprpaper but it can also happen the old version. Also when the client disconnect it will send a message of 0 char and that is expected, with if (messageSize == 0) break; (line 61) it will close the socket connection. Nothing should block ?

[vaxerski]

the client can send a message and then do nothing, blocking hyprpaper.

[cylian914]

its the same thing with the old one ? For the old one it will block at line 62 waiting for the data but the new one will block at line 59.

Also the old one could crash hyprpaper if you connect but immediately exit because it would try to write(ACCEPTEDCONNECTION, m_szReply.c_str(), m_szReply.length()); and having no connection to send (i didn't test it but it should do it)

[vaxerski]

true that... Fine I guess. I'll review this tomorrow. One thing I can definitely say this MR needs is a clang-format

lgtm, thanks!
