MSRV=1.60, use more permissive cfg on test 
* Use cfg(panic = unwind) instead of a check for wasm32 to see if unwinding is supported

This allows the test to run on a future wasm target with exception support as
well as running the test suite with panic=abort on non-wasm targets.

* Bump MSRV to 1.60

impl TrustedLen is unsafe (#1318) 
* impl TrustedLen is unsafe

Implementing `TrustedLen` is now unsafe.

From what I understand, quite a few people are still unhappy about the design since the `unsafe` marker in this case is a promise that `size_hint()` in a *different* impl is accurate, so this may change again.

Anyway, we need to do something to fix our builds, and the alternative is just to remove this (I haven't a clue if it is enabling any important optimisations).

* Remove TrustedLen impl for DistIter

ReseedingRng: fix doc comment on reseeding behavior after UNIX fork (#1317) 
It reads "For ChaCha and Hc128 this is a maximum of fifteen `u32` values before
reseeding" while rand_chacha v0.2.0 or higher actually consumes 63 `u32` values
before reseeding.

7c97f9b86d Merge master and fix conflicts. 
The main change is that Dirichlet now has a const trait N for
the dimension.  The other significant change is to propagate
errors that could occur when Beta:new or Gamma::new is called.
