* Fix recursive attempts to open the log file in the GameLauncher
The AzFramework Application has been updated to default the @user@ and
@log@ aliases to the <engine-root>/user and <engine-root>/user/log
folder respectively if a project isn't set.
Fixed the SystemFile class to support negative offsets if Seek() as per
standard seek function such as fseek
Updated the CrySystem CLog class to use SystemFile instead of FileIOBase
to avoid any asserts that would cause CLog::OpenFile to be recursively
called infinitely
* Removing unused Force Closed variable
* AZ::IO::SystemFile build fixes for Unix platforms. Added a copy constructor for LUAEditorContextInterface.h to fix the LuaEditor build
* Adding missing includes to the WindowsAPI and Android SystemFile headers
Remove from CryCommon and CrySystem:
- MemoryManager and all related classes/files
- StreamEngine, ResourceManager, ImageHandler, and AsyncPakManager
- Various other related interfaces/files/classes etc. that are all now unused
Lots of unrelated removals, I basically tried to remove everything exposed via gEnv that isn't used anymore, and following the threads found a few other things to remove also.
