Further Linux support [+] Begin work on IO futexes for io release on process/thread exit [+] Linux ::readdir iteration [+] AuConsole buffering API [*] Fix sleep as to not get interrupted by signals [*] Switch the type of FS lock used under Linux [*] Linux: Use new IPCHandle encoding scheme [*] Fix undefined behaviour: unintialized timeout values (AuLoop/Linux) [*] Fix undefined behaviour: ConsoleTTY clear line was called of a color of a random value on stack [-] Remainings of std dir iterator [*] Fix pthread_kill (aka send signal to pthread handle) always kills process. This is what you expect bc signal handler inheritance. [*] Reformat the build Aurora.json file [+] Added clang warning ignores to the build file [*] Fix: UNIX need to use STDOUT_FILENO. Was using CRT handle in place of fd by mistake. [+] Linux implementation for IO yield (AuIO::IOYield() - UNIX::LinuxOverlappedYield()) [*] Fix: Linux async end of stream processing. res 0 = zero bytes consumed. <= was detecting this as an error of code 0. Should succeed with zero bytes. [+] Linux LoopQueue missing epilogue hook for the IO processor [*] Various refactors and minor bug fixes [*] Linux fix: Handle pipe EOS as zero [*] Linux fix: thread termination via a user signal of 77. Need a force terminate. [*] IPC handle: fix improper int to bool cast in the header setup within ToString [*] Linux fix: HWInfo CPU topology regression [-] Linux fix: remove SIGABRT handler [*] Missing override in compression, exit, and consoletty headers. [+] Unix Syslog logger backend
