Corinna Vinschen bc444e5aa4 Reapply POSIX ACL changes.
- New, unified implementation of POSIX permission and ACL handling.  The
    new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and
    they allow to inherit the S_ISGID bit.  ACL inheritance now really
    works as desired, in a limited, but theoretically equivalent fashion
    even for non-Cygwin processes.

    To accommodate Windows default ACLs, the new code ignores SYSTEM and
    Administrators group permissions when computing the MASK/CLASS_OBJ
    permission mask on old ACLs, and it doesn't deny access to SYSTEM and
    Administrators group based on the value of MASK/CLASS_OBJ when
    creating the new ACLs.

    The new code now handles the S_ISGID bit on directories as on Linux:
    Setting S_ISGID on a directory causes new files and subdirs created
    within to inherit its group, rather than the primary group of the user
    who created the file.  This only works for files and directories
    created by Cygwin processes.

Corinna Vinschen 859c10beee autload.cc: Avoid clobbering return address in noload on i686
This fixes a long-standing problem when GetProcAddress fails
	to load a function.  The noload code calls SetLastError on
	i686 without saving the edx register.  Starting with Windows 7,
	SetLastError apparently uses $edx and the register is set to
	0x00000000 on return.  So the subsequent `jmp *$edx' in noload
	supposed to return to the caller, actually jumps to address NULL,
	which results in a SEGV.

        * autoload.cc (noload): i686 only: Save and restore $edx when calling
        SetLastError to avoid clobbering return address stating with Windows 7.
