Add _console_read() implementation which is called by the read syscall (does not work yet!)

Instead of "char *" to avoid compiler warnings.
This is OK because "cs" is only used as input of strcmp.

+# Newlib - a C Standard Library for Casio Calulators
+
+## Motivation
+Until now there was no complete [C standard library]([https://en.wikipedia.org/wiki/C_standard_library]) (aka libc) available for the Casio calculators. Although some parts of this library have been provided by fxlib and [gint](https://git.planet-casio.com/lephe/gint), there was no libc implementation complying with the standard and compatible with the sh3eb architecture ready to use.
+
+To change that, I decided to port [newlib](https://sourceware.org/newlib/) to the Casio CPU. Newlib is an alternative libc implementation intended for use on embedded systems.
+
+## Alpha
+Follow this link and click the download button in the top right corner:
+
+[v1.1](https://git.planet-casio.com/Memallox/libc/tags/sh3eb_v1.01)
+
+
+## Installation
+*For a complete tutorial on how to setup a toolchain for Casio calculators, see [Compiler sous Linux avec GCC](https://www.planet-casio.com/Fr/programmation/tutoriels.php?id=61#E7).*
+
+To build newlib, you first need binutils and gcc for the target `sh3eb-elf`. Make sure to configure gcc with the arguments `--with-newlib --without-headers`.
+
+Now you can install newlib. Simply call configure and make:
+
+```bash
+../newlib-cygwin/configure --target=sh3eb-elf --prefix=...
+make
+make install
+```
+
+Afterwards, you have to build gcc again with the argument `--with-newlib`.
+
+For a more detailes tutorial about how to setup newlib in general, see this [more detailed turorial](http://www.ifp.illinois.edu/~nakazato/tips/xgcc.html#newlib).
+
+
+## Features for Casio fx9860g calculators:
+* C standard library libc
+    * printf implementation to print text to the display
+    * Dynamic allocation of memory using malloc and free
+    * Memory manipulation using memcpy, memcmp, memset etc.
+    * String manipulation using strcpy, strcmp, strstr, strtok
+    * ...
+* Math library libm
+    * Floating point arithmetics
+    * ...
+* Automatic library and include path recognition after installation
+* Basic Casio features:
+    * implementation of GetKey, Bdisp_AllClr_DDVRAM, Bdisp_PutDisp_DD, Print and locate without fxlib (but you can use it if you want)
+
+
+# Further information
+## Upstream Repository
+
+Newlib provides releases in their [ftp directory](ftp://sourceware.org/pub/newlib/index.html) and their code on their [git repository](https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git). I try to rebase my fork regulary to their master branch to keep it up-to-date.
+
+## The target `sh3eb-elf`
+
+There is a [great explanation](https://wiki.gentoo.org/wiki/Embedded_Handbook/Tuples) on the naming convention of targets. To really understand what `sh3eb-elf` means, I'll boil it down for you:
+
+To compile code for our Casio calulator, we need to tell newlib where we want to run the code. In our case, the *target*'s name is `sh3eb-elf`.
+
+`sh` is here short for the [SuperH](https://www.renesas.com/us/en/products/microcontrollers-microprocessors/superh.html#) processor architecture. (Fortunately, newlib supports SuperH the  by default.)
+
+To be more specific, `sh3` is a 32-bit CPU architecture of the SuperH family. Furthermore, `eb` stands for the `big endian` format (that indicates the [byte order](https://en.wikipedia.org/wiki/Endianness) used for multi-byte variables). Usually a target also indicates a vendor which in this case is `unknown`. Lastly, the end of the target's name is `elf` (which is usually the kernel). Here, we have no kernel (and hence no operating system) at all.
+
+For newlib, the target `sh3eb` had to be specifically added.

+! Fast SH memcpy
+!
+! by Toshiyasu Morita (tm@netcom.com)
+! hacked by J"orn Rernnecke (joern.rennecke@superh.com) ("o for o-umlaut)
+! SH5 code Copyright 2002 SuperH Ltd.
+!
+! Entry: ARG0: destination pointer
+!        ARG1: source pointer
+!        ARG3: byte count
+!
+! Exit:  RESULT: destination pointer
+!        any other registers in the range r0-r7: trashed
+!
+! Notes: Usually one wants to do small reads and write a longword, but
+!        unfortunately it is difficult in some cases to concatanate bytes
+!        into a longword on the SH, so this does a longword read and small
+!        writes.
+!
+! This implementation makes two assumptions about how it is called:
+!
+! 1.: If the byte count is nonzero, the address of the last byte to be
+!     copied is unsigned greater than the address of the first byte to
+!     be copied.  This could be easily swapped for a signed comparison,
+!     but the algorithm used needs some comparison.
+!
+! 2.: When there are two or three bytes in the last word of an 11-or-more
+!     bytes memory chunk to b copied, the rest of the word can be read
+!     without side effects.
+!     This could be easily changed by increasing the minumum size of
+!     a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2,
+!     however, this would cost a few extra cyles on average.
+!     For SHmedia, the assumption is that any quadword can be read in its
+!     enirety if at least one byte is included in the copy.
+!
