Eliminate backtrace_if_absent in Error::context
...
This avoids stepping through the list of causes when adding context to
the anyhow::Error type which is known to already hold a backtrace.
Reduces the release-mode time of the following loop from 4 seconds to 4
milliseconds.
let mut err = anyhow!("...");
for _ in 0..25000 {
err = err.context("...");
}

Work around bad diagnostic when missing Context import

Previously the compiler would say:
error[E0599]: no method named `context` found for type `std::result::Result<(), anyhow::error::Error>` in the current scope
--> src/main.rs:83:13
|
83 | context(...)?;
| ^^^^^^^ method not found in `std::result::Result<(), anyhow::error::Error>`
|
= help: items from traits can only be used if the trait is in scope
help: the following trait is implemented but not in scope; perhaps add a `use` for it:
|
19 | use anyhow::context::Context;
where the `anyhow::context::Context` in the suggestion is not a path
that is accessible to the user.
