- Implement handle access checking on all console functions.

Browse source 
- OpenConsoleW: Fourth parameter is actually share mode (passing a number from 0 to 2 will usually give ERROR_SHARING_VIOLATION on Windows)
- CreateFileW: Move CONIN$/CONOUT$ handling after dwCreationDisposition checks (it must be valid, even though it doesn't matter which it is); pass FILE_SHARE_READ|FILE_SHARE_WRITE to OpenConsoleW (dwShareMode is ignored).
- CloseConsoleHandle, CsrReleaseObject, CsrVerifyObject: Remove IsConsoleHandle checks - Windows ignores lower 2 bits of handle for closing and verifying.
- SetConsoleMode: Remove IsConsoleHandle check - it's redundant, since the same check is done in CsrGetObject.
- CsrIsConsoleHandle, CsrReleaseObjectByPointer: Clean up a bit.
- CsrFreeConsole: Remove the process from the console's list.
