EOL Normalization

One out of the three replay files uses CRLF line endings while
the other two use LF line endings.

Almost all C files use CRLF endings except mvhist.c and common.h
which use both CRLF and LF at the same time.

All files are modified so that they are stored in the repo
with LF line endings. Also while a .gitattributes file is introduced
to instruct git to normalize all files except image files and VS files.
