Was getting segfaults with multiple services using
`x-develop` and `watch` at the same time. Turns out
the Moby path matcher lazily initializes the regex
pattern internally the first time it's used, so it's
not goroutine-safe.
Change here is to not use a global instance for the
ephemeral path matcher, but a per-watcher instance.
Additionally, the data race detector caught a couple
other issues that were easy enough to fix:
* Use the lock that's used elsewhere for convergence
before manipulating
* Eliminate concurrent map access when triggering
rebuilds

Big change here is to import the ephemeral ignore set from Tilt.
The `.git` directory is also ignored for now: this restriction
should probably be lifted and made configurable in the future,
but it's not generally important to watch and triggers a LOT of
events (e.g. Git creates `index.lock` files that will appear and
disappear rapidly as terminals/IDEs/etc interact with Git, even
for read-only operations).
The Tilt-provided ephemeral file set has been slowly devised over
time based on temporary files that can cause trouble. We can also
look at a more robust/configurable solution here in the future,
but thse provide a reasonable out-of-the-box configuration for
the moment.
There's also some small tweaks to the output to add missing
newlines in a few edge cases and such.

Currently the emacs ignore patterns include `**/.#*` (lock files), but
doesn't include `**/#*#` (autosave files;
https://www.emacswiki.org/emacs/AutoSave, not to be confused with
`**/*~` backup files which are ignored.)
Add autosave files.
When creating files in Go, the stdlib will create (and then rapidly
delete) files ending with `-go-tmp-umask` to determine the umask
to use for permission purposes.
This can cause trouble with Live Update because the files tend to
vanish underneath it, for example.
Fixes#5117.
