libc: Support %i in printf()
...
Which is the same as %d.

Kernel, libc: Fix a big bug in printf()
...
Every time printf flushes the buffer to us in sprintf() or snprintf(), we call strncat to append the data.
But we want to start from the beginning in the first flush. What if there was data already there?
Well, we just append to the old data. Which is not good, and breaks snprintf()'s maximum size policy.
This fix sets the first byte of str to NULL, to avoid this.

libc: make fprintf actually write to the chosen file
...
Also, printf now is kind of an alias for fprintf(stdout,...), as it should be.

Add %m to userspace printf
...
%m as a format specifier is a nonstandard glibc extension, but I like it so I'm implementing it.
What it does is print the value of strerror(errno), without consuming any arguments to printf().

Forgot to add break :)

And that, is why you test before pushing and commiting >.<

Kernel, libc: Implement %p in *printf()
...
So we can avoid writing (unsigned long)ptr or (uint64_t)ptr everywhere when wanting to print a pointer.

libc: Add strncpy and strncat, and deprecate strcpy and strcat (which, since we're building with -Werror, is an instant ban from using these functions)

Add vprintf, (v)sprintf and (v)snprintf to libc + move the non v-printfs to stdio.cpp, since they can now call their v-variants and thus don't depend on internal_printf

Add printf() and puts(), quite primitive, looks like hex printing isn't there yet...
