7f6c6945ae Fix for slice_to_components 
Using `slice_to_components` wouldn't compile because `s.data` is type of `rawptr` and return type is `^T`

61c581baeb core/sys/unix: Add syscalls_linux.odin 
Linux is in the unfortunate situation where the system call number is
architecture specific.  This consolidates the system call number
definitions in a single location, adds some wrappers, and hopefully
fixes the existing non-portable invocations of the syscall intrinsic.

672fc9fc4d core/mem: Add zero_explicit 
This call is intended to provide the ability to securely scrub memory
without compiler interference, in a similar manner to explicit_bzero,
memset_s, SecureZeroMemory.

The approach taken is a volatile memset followed by a seqentially
consistent memory fence, to prevent the call from being optimized away
by DSE, and from being reordered.  An identical approach is currently
being used by the zeroize Rust crate, and is effective in practice.

LLVM IR output:
```
; Function Attrs: nounwind
define internal i8* @mem.zero_explicit(i8* %0, i64 %1) #0 {
decls:
  call void @llvm.memset.p0i8.i64(i8* %0, i8 0, i64 %1, i1 true)
  fence seq_cst
  ret i8* %0
}
```
