In the snapshot tool the files were opened in text mode. However the snapshot files are binary files thus it is advised to use the binary mode when opening the files. Specifying the binary mode is a must on Windows platform otherwise the read/write operations are inserting extra '\r' characters. To make the tools consitent across OSes all fopen are now opening files in binary mode. Also update jerry-libc to accept the 'b' modifier and add a test case where the JS file uses CR-LF line endings. JerryScript-DCO-1.0-Signed-off-by: Peter Gal pgal.u-szeged@partner.samsung.com
