some additional adjustments for correctness.

80e3f8941d Add blanket TryFrom impl when From is implemented. 
Adds `impl<T, U> TryFrom<T> for U where U: From<T>`.

Removes `impl<'a, T> TryFrom<&'a str> for T where T: FromStr` due to
overlapping impls caused by the new blanket impl. This removal is to
be discussed further on the tracking issue for TryFrom.

6738cd4d47 Auto merge of #40281 - jimmycuadra:try-from-from-str, r=aturon 
Rename TryFrom's associated type and implement str::parse using TryFrom.

Per discussion on the tracking issue, naming `TryFrom`'s associated type `Error` is generally more consistent with similar traits in the Rust ecosystem, and what people seem to assume it should be called. It also helps disambiguate from `Result::Err`, the most common "Err".

See https://github.com/rust-lang/rust/issues/33417#issuecomment-269108968.

`TryFrom<&str>` and `FromStr` are equivalent, so have the latter provide the former to ensure that. Using `TryFrom` in the implementation of `str::parse` means types that implement either trait can use it. When we're ready to stabilize `TryFrom`, we should update `FromStr` to
suggest implementing `TryFrom<&str>` instead for new code.

See https://github.com/rust-lang/rust/issues/33417#issuecomment-277175994
and https://github.com/rust-lang/rust/issues/33417#issuecomment-277253827.

e7b0f2badf Remove function invokation parens from documentation links.

2add6ac14a Add a name for the parameter to TryFrom::try_from. 
Although signatures with anonymous parameters may not be deprecated or
removed at this point, the team seems to agree that the ability to have
an anonymous parameter is unfortunate historical baggage, and that we
shouldn't create new code that uses it.

Fix subject-verb agreement in copypasta: "`AsRef` dereference" to
"`AsRef` dereferences".

Formalize "eg" to "e.g." Italicization of common Latin abbreviations
seems to be going out of style in written English, so I left it plain.

c14d86fd3f core: Split apart the global core feature 
This commit shards the broad `core` feature of the libcore library into finer
grained features. This split groups together similar APIs and enables tracking
each API separately, giving a better sense of where each feature is within the
stabilization process.

A few minor APIs were deprecated along the way:

* Iterator::reverse_in_place
* marker::NoCopy
