Michael Howell 2df14c3701 Add a lint to warn on `T: Drop` bounds 
**What it does:** Checks for generics with `std::ops::Drop` as bounds.

**Why is this bad?** `Drop` bounds do not really accomplish anything.
A type may have compiler-generated drop glue without implementing the
`Drop` trait itself. The `Drop` trait also only has one method,
`Drop::drop`, and that function is by fiat not callable in user code.
So there is really no use case for using `Drop` in trait bounds.

**Known problems:** None.

**Example:**
```rust
fn foo<T: Drop>() {}
```

Shotaro Yamada 2ee713dc7b Catch up with `format_args` change 
Catches up with a change in rust-lang/rust#57537

Happened to fix a bug in `expect_fun_call`, that is the lint ignores more than
one arguments to `format`.

Fix c_void false positive caused by libc refactoring 
The path of `libc::c_void` has changes in 5c1a6b8a6d
The DefId path is now always platform specific like
`libc::windows::c_void`. This fixes our c_void detection to only check
the first and last elements.
