Don't trigger longjmp in rust.
...
Motivation behind this change is upcoming breaking change in Rust
compiler v1.52.0 to prevent unwinding across FFI boundaries.
https://github.com/rust-lang/rust/pull/76570
The new functionality requires nightly compiler to declare FFI
functions as "C-unwind".
The fundamental solution is to use C shim to wrap "e" and "m"
Lua functions in pcall.
Additionally define Rust calling convention to trigger lua_error
on Rust behalf.

Improve the situation with numerical conversion
...
This is a somewhat involved change with two breaking API changes:
1) Lua::coerce_xxx methods now return Option (this is easier and faster than
dealing with Result)
2) rlua numeric conversions now allow more loss of precision
conversions (e.g. 1.5f32 to 1i32)
The logic for the first breaking change is that mostly the coerce methods are
probably used internally, and they make sense as low-level fallible casts and
are now used as such, and there's no reason to confuse things with a Result with
a large error type and force the user to match on the error which will hopefully
only be FromLuaConversionError anyway.
The logic for the second change is that it matches the behavior of
num_traits::cast, and is more consistent in that *some* loss of precision
conversions were previously allowed (e.g. f64 to f32).
The problem is that now, Lua::coerce_integer and Lua::unpack::<i64> have
different behavior when given, for example, the number 1.5. I still think this
is the best option, though, because the Lua::coerce_xxx methods represent how
Lua works internally and the standard C API cast functions that Lua provides,
and the ToLua / FromLua code represents the most common form of fallible Rust
numeric conversion.
I could revert this change and turn `Lua::eval::<i64>("1.5", None)` back into an
error, but it seems inconsistent to allow f64 -> f32 loss of precision but not
f64 -> i64 loss of precision.

Tried to explain the rationale for safety around callbacks in Lua and Scope a
bit better, because every time I don't look at this for a while I forget my
reasoning. I'm not always so great at using the right terminology, so to
whoever reads this, if I got this wrong please tell me.

Initial design for non-'static scoped userdata
...
Uses the same UserData trait, and should at least in theory support everything
that 'static UserData does, except that any functions added that rely on
AnyUserData are pretty much useless.
Probably pretty slow and I'm not sure how to make it dramatically faster, which
is a shame because generally when you need non'-static userdata you might be
creating it kind of a lot (if it was long-lived, it would probably be 'static).
Haven't added tests yet, will do that next.

Solve (maybe) *another* soundness issue with `Lua::scope`
...
Callbacks should not be able to capture their arguments and hold onto them,
because the `&Lua` used in previous calls will not remain valid across calls.
One could imagine an API where the specific `&Lua` is simply stored inside the
`Scope` itself, but this is harder to do, and would (badly) encourage storing
references inside Lua userdata.
Ideally, the only way it should be possible to store Lua handles inside Lua
itself is through usafety or the `rental` crate or other self-borrowing
techniques to make references into 'static types. If at all possible this
roadblock should stay, because reference types inside userdata are almost always
going to lead to a a memory leak, and if you accept the risks you should just
use `RegistryKey` with its manual removal.

Remove out of date documentation, simpler scope lifetimes
...
The documentation describing it being a logic bug to access "outer" callback
handles when inside an "inner" callback is inaccurate, that was only true when
using an older design for handle values.
Also, there is no reason to have a separate 'callback lifetime, because 'scope
is already invariant and just using 'scope seems equivalent.
