Summary:
TreeSpans used to use `&str`, which adds a lifetime to the struct, making it
harder to be used in the Python land. Use a type parameter so TreeSpans<String>
can be used.

Summary:
Drop stdoutbytes/stdinbytes. They make things unnecessarily complicated
(especially for chg / Rust dispatch entry point).
The new idea is IO are using bytes. Text are written in utf-8 (Python 3) or
local encoding (Python 2). To make stdout behave reasonably on systems not
using utf-8 locale (ex. Windows), we might add a Rust binding to Rust's stdout,
which does the right thing:
- When writing to stdout console, expect text to be utf-8 encoded and do proper decoding.
- Wehn writing to stdout file, write the raw bytes without translation.
Note Python's `sys.stdout.buffer` does not do translation when writing to stdout console
like Rust's stdout.
For now, my main motivation of this change is to fix chg on Python 3.

All diff functions are (bytes, bytes) -> bytes to preserver

Because of that I had to add ui.writebytes output function that accepts

Summary:
This allows us to incrementally abstract away parts related to filesystem from
Log. For example, instead of using std::fs to access filesystem directly, use
methods on the GenericPath instead.
Right now the main motivation is to add support for "multi-logs" sharing a single meta
file. To do that, methods reading and writing metas are moved to the
GenericPath type.
This also unifies the open functions. Now OpenOptions::create_in_memory can be
private. Empty in-memory Logs can be opened via `open(())`.

Summary:
The environment variable `EDENSCM_TRACE_OUTPUT` specifies where to write the
tracing output for the current command. Environment variables are inherited
by subprocesses by default. That is undesirable because another hg command
(triggered by hook, or background maintaince) will rewrite the trace output.
Avoid it by unsetting EDENSCM_TRACE_OUTPUT for subprocesses.

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:
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.
