Tracking issue for r10

[9ary]

• Split iplboot into stages 1 (modchip flash, bare minimum to load a DOL from local storage) and 2 (config support, USB/network boot, controller shortcuts...)
• Implement preloader stage (no libc/libogc2, can boot a recovery tool from SD card or chainload to gekkoboot proper)
• Only disable Qoob in Qoob builds, check what needs to be done before that, and whether it's necessary for Qoob SX
• Implement our own, source-built BS1 replacement
• Deferred video init - initialize video at the last moment there isn't really a reasonable way to do this
• No media/no stage 2 DOL should be a hard error and halt, rather than reset to the IPL
• Configuration file using INIH or https://github.com/compuphase/minIni
  • Support glob patterns using fnmatch
  • Remove all the hardcoded paths
  • Shortcut timeout
  • Configurable remote boot priority and timeout
• Stealth mode - SRAM setting (SYS_Get/SetBootMode) to skip iplboot by default
• Use FatFs more correctly, replace the current IFACE global with FF_STR_VOLUME_ID
• Fix Button shortcuts unusable with wireless controllers #25
• Look into Mysterious crash #26, it should at least not crash
• Improve logging
• m2loader support #44
