Join the license header with historical comments using a separator so IDEs can correctly parse the initial header.
Also use .gitattributes to ensure all files are LF.
The vast majority of this is fixing up `char *` that should be `const char *`
but a handful of other fixes, like potential buffer overflows that GCC
noticed, etc, were applied as well.
This removes `-Wno-write-strings` from CMakeLists.txt, as it is no longer
necessary, as there is no longer a flood of compiler warning spam when
building.
This does not fix all compiler warnings; there are still a handful, and they
are legitimate, but they can be dealt with in a future commit.
- tabs to spaces
- use Unix line endings everywhere
- newline at end of file
- remove trailing white space
- no space between keywords and opening parenthesis
- use 2 spaces to indent
Most of these warnings are due to the use of NULL instead of 0 or NULL instead of '\0'.
Some are macro redefinitions. None of them are pointer storage related. Those will be
in another PR.
