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:
Translate alias like `echo = !echo foo` to `echo = debugrunshell '--cmd=echo
foo'`. This enables the Rust shell alias handling code path. The Python
shell alias handling was removed.
The majority part of `test-alias.t` still passes. That includes some "weird"
shell alias features.
This has some test changes, through:
- `$HG_ARGS` is no longer supported. And tests depending on it are changed.
`$@` will be the alternative for most cases.
Practically, our `$HG_ARGS` users seem to come from
https://stackoverflow.com/a/833387, which does not seem to use `$HG_ARGS`
correctly (since `$HG_ARGS` includes the command name).
- Early-parse commands (ex. `hg log -b '--config=alias.log=!echo
howdy'`) no longer works.
- The warning `--repository ignored` now shows up, since `debugrunshell`
is a "no-repo" command.
- Global flags can no longer be used after shell aliases. Supporting them
is a head-ache.
- `circular alias` error message changed because it's now reported by the Rust
code, which does not report all alias names right now.

CommandError happens if there is an unknown command flag, or a required
argument is missing. The old behavior is to print an error message to
stderr, then start the pager with the command help printed to stdout.
There are 2 problems with that approach:
1. When using mosh, a long help text might flush the actual error to out of the
screen. The error message will be missed.
2. When captured in shell scripts, the help text printed to stdout would be
captured, which is almost always undesirable.
The actual motivation of this change is for 2. Zsh themes like bullet-train [1]
uses `hg id -b 2>/dev/null` and we'd like to remove `id -b` support. After that,
the command should not polluate stdout with help text.

D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`.
That has nasty problems if both `import mercurial` and
`import edenscm.mercurial` are used, because Python would think `mercurial.foo`
and `edenscm.mercurial.foo` are different modules so code like
`try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)`
would fail to handle the `edenscm.mercurial` version. There are also some
module-level states (ex. `extensions._extensions`) that would cause trouble if
they have multiple versions in a single process.
Change imports to use the `edenscm` so ideally the `mercurial` is no longer
imported at all. Add checks in extensions.py to catch unexpected extensions
importing modules from the old (wrong) locations when running tests.

Summary:
Our codebase is already unfriendly to 3rd-party extensions and we will likely
break the compatibility as part of revisising / replacing components in Rust
anyway. So just stop supporting `--config extensions.3rdpartyfoo=`.
Note `--config extensions.3rdpartyfoo=foo.py` still works.
This also makes `ImportError` more meaningful. Previously, when `hgext.foo`
imports `bar` which does not exist, the error is "cannot import foo", while
it should really be "cannot import bar". That is because extensions.py falls
back to import `hgext3rd.foo`, and `foo`. Now extensions.py only tries
`hgext.foo` and will suface the right error.

It's necessary to define this as a shell function instead of an hgrc alias to prevent tests that list aliases from printing it. Plus that enforces a nice separation of test/stdlib logic.

ad1bdea (dispatch: defer environment variable resolution in alias commands
(BC), 2016-05-06) made environment variables lazily resolved. But after
D805 (alias: make alias command lazily resolved 2017-09-23), alias
resolution happened after uisetup, which breaks the test for chg.
`uisetup` is known to behave different in chg. Let's verify the feature
without using `*setup`.
Differential Revision: https://phab.mercurial-scm.org/D912
Before this patch, if there are environment variables in an alias command,
they will be expanded immediately when we first see the alias.
This will cause issues with chg, because environment variable updates will
not propagate to expanded arguments.
This patch makes "args" of "cmdalias" a property that will be calculated
every time when accessed.
When "hg.bat" is invoked via interactive shell "cmd.exe" on Windows,
it can store own exit code into ERRORLEVEL correctly, regardless of
explicit "exit" statement in it: "cmd.exe" seems to hold ERRORLEVEL
updated by the last command in the batch file (= "python hg", in
"hg.bat" case).
On the other hand, "hg.bat" is invoked indirectly via
"subprocess.Popen" (e.g. shell alias, hooks, hgclient and so on), the
parent process always receives exit code 0 from spawned "hg.bat":
batch files on Windows seem not to be really spawned like as shell
scripts on UNIX, but to be executed in the "cmd.exe" process.
This patch returns exit code explicitly for indirect invocation.
"/b" should be specified for "exit" to prevent "cmd.exe" from being
terminated when "hg.bat" is invoked interactively from it.
Before this patch, a part of "test-alias.t" fails unexpectedly on
Windows environment, because "cmd.exe" can't evaluate "$HG_ARGS"
expression in shell alias correctly.
This patch uses "%HG_ARGS%" in shell alias on Windows instead of
"$HG_ARGS" to expand it correctly.
When 62900f2373fa introduced phases to the `hg log --debug` output, it
also disabled outputting public phase. At the same time, it always
shows phases in the default template, `hg log --debug -T default`.
Those two should produce the same output, but they don't.
I think it makes a lot more sense to always show all phases. There's
already loss of backwards compatibility in this case when using a
newer hg on an old hg repo, since draft commits will show up in the
output of `hg log --debug`.
Finally, I just don't think that any sort of information should be
hidden with --debug. This flag should be about showing as much
information as possible.
Before this patch, the shell alias causes failure when it takes its
specific (= unknown for "hg") options in the command line, because
"_parse()" can't accept them.
This is the regression introduced by 7849ac1dbc57.
It fixed the issue that ambiguity between shell aliases and commands
defined by extensions was ignored. But it also caused that ambiguous
shell alias is handled in "_parse()" even if it takes specific options
in the command line.
To avoid such failure, this patch checks shell alias again after
loading extensions.
All aliases and commands (including ones defined by extensions) are
completely defined before the 2nd (= newly added in this patch)
"_checkshellalias()" invocation, and "cmdutil.findcmd(strict=False)"
can detect ambiguity between them correctly.
For efficiency, this patch does:
- omit the 2nd "_checkshellalias()" invocation if "[ui] strict= True"
it causes "cmdutil.findcmd(strict=True)", of which result should
be equal to one of the 1st invocation before adding aliases
- avoid removing the 1st "_checkshellalias()" invocation
it causes "cmdutil.findcmd(strict=True)" invocation preventing
shell alias execution from loading extensions uselessly
