fix(network): Port merged TheSuperHackers lobby and network leak fixes

[tintinhamans]

Ports four merged upstream leak fixes in the LAN and network code. Each is a cherry-pick -x of the upstream commit.

• fix(lanapi): Fix GameInfo memory leaks in LANAPI::OnGameStart(), LANAPI::RequestGameLeave() TheSuperHackers/GeneralsGameCode#3462 fix(lanapi): Fix GameInfo memory leaks in LANAPI::OnGameStart(), LANAPI::RequestGameLeave()
• bugfix(network): Close sockets that fail to bind TheSuperHackers/GeneralsGameCode#3488 bugfix(network): Close sockets that fail to bind
• fix(network): Release the disconnect chat message after sending it TheSuperHackers/GeneralsGameCode#3498 fix(network): Release the disconnect chat message after sending it
• fix(lanapi): Delete the lobby player when they leave the lobby TheSuperHackers/GeneralsGameCode#3499 fix(lanapi): Delete the lobby player when they leave the lobby

For TheSuperHackers#3462 the GameInfo destructor that upstream adds already exists on this branch, so only the virtual destructors on the subclasses and the LANAPI changes are taken. The Recorder.h and GameSpyGameInfo.h changes are applied to both the Generals and GeneralsMD copies, Recorder.h with just the one destructor line because those files differ from upstream.

Zero Hour (z_generals) builds here. The Generals copies of Recorder.h and GameSpyGameInfo.h were not compiled, g_generals does not build on this branch.
