Summary:
This has a bunch of benefits:
- "duration_ms" counts Python startup overhead, and does not count the missing
"chg pager blocked" at the end of chg process.
It's more desirable than other kinds of "duration"s.
- Max RSS is logged. So we might get rid of a seprate wrapper eventually.

Summary:
This will provide the "fullargs" information needed by telemetry.
Log in "hgcommands", instead of "hgmain", or "clidispatch", because:
- "clidispatch" does not have argv[0], and might be called multiple times
(from Rust, then from the fallback Python -> bindings)
- Logs in "hgmain" won't be written to disk if chg is used.
I removed "env", since "hgcommands" does not have access to hgrc to decide what
env to log. It seems desirable if the "env" logging is move to a fb-only
backgroud logging binary.

Summary:
Global states (For example, the global blackbox instance, potentially some
logging / tracing libraries) are separate in the Rust and Python worlds.
That is because related code gets compiled separately:
bindings.so (top-level)
\_ blackbox
hgmain (top-level)
\_ blackbox (have a different global instance than the above blackbox)
To address it, make `bindings` a builtin module in `hgmain`.
The builtin module was renamed from `edenscmnative.bindings` to `bindings` so
it does not require importing anything else (For example, `edenscmnative`).
This unfortunately makes `hg` 100+ MB. Fortunately it can be compressed well
(gzip: 31MB).

Summary: I think these are left over from pre-2018 code where they may have been necessary. In 2018 edition, import paths in `use` always begin with a crate name or `crate`/`super`/`self`, so `use $ident;` always refers to a crate. Since extern crates are always in scope in every module, `use $ident` does nothing.

Summary:
Some functions in `dispatch.rs` are about the "repo". Move them to a better
place - `repo.rs`.
The repo and config logic is coupled. A new enum `OptionalRepo` was added, to
make code easier to write - `Some(repo)` means the repo exists, and `repo` owns
the config. `None(config)` means the repo is missing, but the config is still
available.

Summary:
Change error type in clidispatch from `DispatchError` to `failure::Error`.
Pros:
- `failure` will attach a backtrace for free. (otherwise, backtrace handling is
manual)
- Wrapping other errors (ex. `io::Error`, `cliparser::Error`) is optional.
(otherwise, wrapping other errors is mandatory, and needs to be careful to
not lose information)
Cons:
- No longer able to enumerate *all* possible error types. (but can still
downcast to specific errors)
This seems to be a good tradeoff especially because of the backtrace handling - I
ran into a few issues where the location where the error happened really helped
debugging.
Since we can no longer enumerate all possible error types, the enum was changed
to individual structs to make the code shorter (ex. the struct can be downcasted
directly, instead of down-casting to the enum, then matching its variant).
The `HighLevelError` handling was simplified and moved to `hgmain`.
The new code path falls back to Python less aggressively, therefore some behaviors
were tweaked (ex. `-R` takes a bundle path).

Summary:
The `Dispatcher` provides lots of features but its internal state only contains
the command table. Replace it with `CommandTable` and make the methods free
functions.
This makes function dependencies more cleaner, for example things like "locating
a repo", "getting the args" etc. won't require a `Dispatcher`.
A side effect of this change is the non-utf8 command line arguments are no longer
supported. This is already broken since our hg wrapper (accidentally) enforced
utf-8 command line. Therefore related tests are removed.

Summary:
Previously, the command table state in `Dispatcher` is confusing:
command_table: BTreeMap<String, CommandFunc>,
commands: BTreeMap<String, CommandDefinition>,
Question: In what case do these BTreeMaps have different keys?
It does not make much sense. Therefore merge `CommandFunc` into
`CommandDefinition`, and remove the `command_table` field.
This affects the `register` API:
fn register(&mut self, command: CommandDefinition, f: FN)
`f` is part of `CommandFunc`, which duplicates with `CommandDefinition`.
`CommandDefinition` contains 3 things: name, doc, and flags.
In the new `define_flags!` world, `flags` can be inferred from the type
of the function, so only `name` and `doc` are needed. Therefore change
the register function to:
fn register(&mut self, f: FN, name: &str, doc: &str)
Update `hgcommands` to use the newer APIs. Commands can now be registered
without going through `CommandDefinition` explicitly.

on *multiple* libraries that depend on `cpython`, there will be a link error
with `cargo build` complaining about lots of CPython APIs do not exist.
With this change, `hgcommands` will be the only crate that `hgmain` depends
on, therefore no such link issues.
