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.

The input permission flags consist of two groups:
( S_IRUSR | S_IRGRP | S_IROTH ) -- S_ACC_READ
( S_IWUSR | S_IWGRP | S_IWOTH ) -- S_ACC_WRITE
The only thing we can set, at this point, is whether or not
this is a SYSTEM file. If the group and other bits are
zero and the user bits are non-zero then set SYSTEM. Otherwise
the attributes are zero.
The attributes can be set later using fcntl().
The input permission flags consist of the following flags:
O_RDONLY -- open for reading only
O_WRONLY -- open for writing only
O_RDWR -- open for reading and writing
O_ACCMODE -- mask for above modes
O_NONBLOCK -- no delay
O_APPEND -- set append mode
O_CREAT -- create if nonexistent
