Summary:
The bindings APIs are out of date.
The latest idea is to write non-master commits to disk, in a different group.
There are no "segments in memory". Therefore:
- Rename `builddisk` to `build`.
- Make sure `build` updates internal states by calling `reload`.
- Drop `buildmem`.
- In case `builddisk` gets called very frequently, reduce its overhead by
doing nothing if all commits are built already.
The constructor is revised to match the latest interface (no
"max segment level" and "set_new_segment_size" needs to be called).

Summary:
The Mercurial code has the bad habbit of inserting files in what can
appear impossible locations. Sometimes files with directory names and
sometimes directories in file locations. This happens because the initial
code would do additions before deletions on Manifest implementations that
were rudimentary. As soon as we introduce validation various code paths
surface.
I tried to fix the codepaths that modify manifests but it's a losing game.
I fixed the issue that appeared in tests and a couple of issues people
reported but more situations crop up.
This is giving up on the python code.

Summary:
This diff replaces eden's dependencies on failure::Error with anyhow::Error.
Failure's error type requires all errors to have an implementation of failure's own failure::Fail trait in order for cause chains and backtraces to work. The necessary methods for this functionality have made their way into the standard library error trait, so modern error libraries build directly on std::error::Error rather than something like failure::Fail. Once we are no longer tied to failure 0.1's Fail trait, different parts of the codebase will be free to use any std::error::Error-based libraries they like while still working nicely together.

Summary:
Edenapi uses a group of impls like the following as the canonical way to construct ApiError.
```
impl From<Context<ApiErrorKind>> for ApiError {
```
Downstream code would write:
```
use failure::ResultExt;
let stream_trees = config
.get_or_default("edenapi", "streamtrees")
.context(ApiErrorKind::BadConfig("edenapi.streamtrees"))?;
```
This relies on the way that ResultExt::context returns a unique type that is different from failure::Error.
This diff introduces a dedicated extension trait to allow the same code in the caller to continue to work even without a failure::Context<T> type, which will be required for dropping our dependency on failure::Fail and failure.
```
pub trait ApiErrorContext<T> {
fn context(self, kind: ApiErrorKind) -> ApiResult<T>;
}
```
We also introduce a public constructor for ApiError and replace indirect construction that used to look like this:
```
error.context(ApiErrorKind::Curl).into()
```
with this instead:
```
ApiError::new(ApiErrorKind::Curl, error)
```
which is the same number of characters but clearer. The argument order matches [std::io::Error::new](https://doc.rust-lang.org/std/io/struct.Error.html#method.new).

Summary:
This diff is preparation for migrating off of failure::Fail / failure::Error for errors in favor of errors that implement std::error::Error. The Fallible terminology is unique to failure and in non-failure code we should be using Result<T>. To minimize the size of the eventual diff that removes failure, this codemod replaces all use of Fallible with Result by:
- In modules that do not use Result<T, E>, we import `failure::Fallible as Result`;
- In modules that use a mix of Result<T, E> and Fallible<T> (only 5) we define `type Result<T, E = failure::Error> = std::result::Result<T, E>` to allow both Result<T> and Result<T, E> to work simultaneously.
