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.
