rust: Add macro for passing static borrowed strings from Rust to C. 
* ADD a new macro, tor_util::string::cstr!() which takes Rust strings,
   concatenates them together, appends a NUL byte, and converts it into a
   std::ffi::CStr for handing to C.

d8307cb0e9 Remove new unsafe {} use. 
Rationale: this helps for performance only, but we don't actually
have any reason to think that the checks here are
performance-critical.  Let's not normalize the use of unsafe {}.

protover: Fix memleak in Rust impl of protover_compute_for_old_tor. 
* FIXES #25127: https://bugs.torproject.org/25127
 * ADDS a new module to the Rust tor_util crate for small utilities
   for working with static strings between languages.
 * CHANGES the return type of protover_compute_for_old_tor to point to
   immutable data.
 * CHANGES the code from the previous commit to use the new static
   string utilities.

Add Link protocol version 5 to the supported protocols list in protover.rs 
And fix the unsupported protover example so it uses a Link protover much
higher than 5.

Part of  #25070, bugfix on 0.3.3.1-alpha, which introduced the protover crate.

1dab8bae21 smartlist.rs: The libc::c_char type is not the same as i8. 
The code had been using c_char and i8 interchangeably, but it turns
out that c_char is only i8 on platforms where "char" is signed. On
other platforms, c_char is u8.

Fixes bug 24794; bug not on any released Tor.

1969d57363 Change our build process to run Cargo from inside the build tree 
Instead of using the cwd to specify the location of Cargo.toml, we
use the --manifest-path option to specify its location explicitly.

This works around the bug that isis diagnosed on our jenkins builds.

70c067102b Allow Rust build using locally supplied crates or crates.io 
This adds a couple of configure commands to control whether we're
requiring all dependencies to be available locally (default) or not
(--enable-cargo-online-mode). When building from a tarball, we require
the RUST_DEPENDENCIES variable to point to the local repository of
crates. This also adds src/ext/rust as a git submodule that contains
such a local repository for easy setup.

d6f9a4f11a cargo-online-mode configure argument 
Passing --enable-cargo-online-mode during configure allows cargo to make
network requests while building Tor or running tests. If this flag is
not supplied, the dependencies need to be available in the form of a
local mirror.
