thcrap: Implement hot-repatching

[nmlgc]

Hot-repatching

Description

With this feature, newly downloaded binary hacks, breakpoints and other patch data loaded on initialization could immediately be re-applied after a patch update was downloaded, without having to restart the game.

Prerequisites

• Breakpoint removal
• File change notifications also need to work with ZIP files, preferably without having to care whether patch files comes from a ZIP or a real directory structure.

Implementation

• Each plug-in (and the core) can export a thcrap_plugin_repatch() function.
• thcrap_repatch() calls each DLL's thcrap_plugin_repatch().
• Using the file change notification functions of the Win32 API, this function is also called whenever the user changes a file locally.
