* Implement some IPC related kernel SVCs properly * Fix BLZ decompression when the segment also has a uncompressed chunck * Set default cpu core on process start from ProgramLoader, remove debug message * Load process capabilities properly on KIPs * Fix a copy/paste error in UnmapPhysicalMemory64 * Implement smarter switching between old and new IPC system to support the old HLE services implementation without the manual switch * Implement RegisterService on sm and AcceptSession (partial) * Misc fixes and improvements on new IPC methods * Move IPC related SVCs into a separate file, and logging on RegisterService (sm) * Some small fixes related to receive list buffers and error cases * Load NSOs using the correct pool partition * Fix corner case on GetMaskFromMinMax where range is 64, doesn't happen in pratice however * Fix send static buffer copy * Session release, implement closing requests on client disconnect * Implement ConnectToPort SVC * KLightSession init
