Summary:
Clean up some of the calls to `ui.log` and how they appear in blackbox logging.
* Make the names of the events consistently use `snake_case`.
* For watchman, only log once for each watchman command. Include whether or not it failed.
* Unify `fsmonitor` logging under the `fsmonitor` event.
* Omit the second argument when it is empty - it is optional and does nothing when empty.
* Increase the number of blackbox lines included in rage to 100.

Summary:
`ui.log` expects to be called with valid format arguments. If the arguments
are not a valid format string, or the number of arguments doesn't match the
number of format placeholders, formatting will fail.
In this case, catch the exception and fail gracefully. Don't even bother
formatting if there is exactly one argument.
The `blackbox` extension already does this, so extend to the `sampling`
extension.
Also fix the place where `perftrace` calls `ui.log` with a string that might
contain formatting placeholders.

Summary:
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.

Summary:
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:
Add a config option `fsmonitor.detectrace` and environment variable
`HGDETECTRACE`. Once set, perform an additional query to check if there are
writes to the working copy while `wctx._buildstatus()` is being calculated.
Also enable the race detector for all fsmonitor tests.

Summary:
This logs timing data for:
- update
- merge.update
- mergedriver
- applyupdates
- workers
- fetches
- pulls
- remotefilelog prefetches
- treemanifest prefetches
- status
- dirstate walks
- fsmonitor walks
- watchman queries
Hopefully this will let us narrow down where time is going in a number of cases
where the profile data is ambigiuous or hard to come by.

Summary:
In an upcoming diff I want to add more timing measurements for various
parts of the Mercurial code (like how long status takes, vs checkout, vs
prefetch, etc). Let's rename the logblockedtimes logic to be more generic, since
it is doing basically the same thing.
