[*] Fix deadlock in the async subsystem (NoLockShutdown vs Shutdown in exception handler) [+] Added ProccessMap NT variant [+] Added ToolHelp image profiling [*] Improved exception awareness [*] Delegated SpawnThread to isolated TU, ready for reuse for RunAs and XNU Open - now with horrible evil alloc that could fail [+] Added header for future api 'UtilRun' [*] Improve NT core detection [*] Changed small affinity bitmap to AuUInt64 instead of AuUInt32 [+] Added data structure to hold cpuids/affinity masks [+] Implemented logger sinks [+] Implemented logger glue logic [*] Began migrating older loggers to sink-based default devices [*] Minor refactors [*] Improved internal exception discarding, not yet nothrow capable [*] Minor create directory fix
