J Reece Wilson fd0c5b51b2 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
