This removes some of the more casual language.
The only outright goofiness I couldn't bear to remove is "these modules are the bedrock upon which all of Rust is forged, and they have mighty names like `std::slice` and `std::cmp`", which I believe the greatest sentence I have ever created.
part of #24407
I'm not sure whether I should be trying to explain the general rule in the E0210 explanation or just point people to the RFC. However, if we go with the latter option I think that the RFC will need to be revised slightly, since it is not quite as gentle as I would like.
Also, the link to RFC 1023 is not the correct one (it should be https://github.com/rust-lang/rfcs/blob/master/text/1023-rebalancing-coherence.md), but the correct one is too long. I'm aware of @michaelsproul's PR https://github.com/rust-lang/rust/pull/26290 from awhile back, but it doesn't seem to be working. Has there not been a new snapshot yet?
#27360 removed a padding field full of uint8_t's, but didn't remove
the use. This didn't get picked up presumably because (a) bors
doesn't have any BSD builders, and/or (b) #[cfg]'d out blocks don't
get linted.

this makes the second code block consistent with the first code block -- other than being in reversed order, the first code block claims b is u16 and c is u32, whereas the second code block claims the opposite. seems to be an obvious typo.
This is *mostly* reducing *my* use of *italics* but there's some other misc changes interspersed as I went along.
This updates the italicizing alphabetically from `a` to `ra`.

There are still problems in both the design and implementation of this, so we don't want it landing in 1.2.
