StdLib: Add isDirSep character classification macro and function. Implement several Posix functions and clean up EfiSysCall.h. Align file mode handling with UEFI file protocol flags.

Include/ctype.h:             Function declaration and Macro definition of isDirSep
Include/unistd.h:            Declarations added from EfiSysCall.h
Include/utime.h:             New file.  For the Posix utime() function.
Include/sys/_ctype.h:        Update character class bit maps.
Include/sys/EfiSysCall.h:    Move declarations to unistd.h
Include/sys/fcntl.h:         Improve comments.  Add UEFI-specific macros.
Include/sys/filio.h:         Remove declarations for unsupported file ioctls.
Include/sys/stat.h:          Fix flags.  Add macros and declarations.
Include/sys/time.h:          Add declarations for new functions Tm2Efi() and Time2Efi().
Include/sys/types.h:         Use EFI-specific instead of BSD-specific definitions for typedefs.
Include/sys/unistd.h:        Delete inappropriate content.  Guard macro definitions.

LibC/Ctype/iCtype.c:         Update character classification and case conversion tables.
LibC/Time/TimeEfi.c:         Improve comments.  Implement new functions Tm2Efi() and Time2Efi().
LibC/Uefi/StubFunctions.c:   Add missing include.  Cosmetic changes to declarations.
LibC/Uefi/SysCalls.c:        Add support function for utime().
LibC/Uefi/Uefi.inf:          Add LibGen library class dependency.
LibC/Uefi/Xform.c:           Enhance Omode2EFI().
LibC/Uefi/Devices/UefiShell/daShell.c:    Enhance da_ShellMkdir.  Implement da_ShellIoctl to set file times.
PosixLib/Gen/access.c:       New file.  Implement the access() function.
PosixLib/Gen/dirname.c:      Enhance to use isDirSep and differentiate between the device, path, and filename components of UEFI Shell-style paths.
PosixLib/Gen/utime.c:        New file.  Implement the utime() function.
PosixLib/Gen/LibGen.inf:     Change MODULE_TYPE.  Add new files.
