fsmonitor: refresh pywatchman with upstream

This commit vendors pywatchman commit 259dc66dc9591f9b7ce76d0275bb1065f390c9b1
from upstream without modifications. The previously vendored pywatchman
from changeset 16f4b341288d was from Git commit c77452.

This commit effectively undoes the following Mercurial changesets:

* dd35abc409ee fsmonitor: correct an error message
* b1f62cd39b5c fsmonitor: layer on another hack in bser.c for os.stat()
  compat (issue5811)
* c31ce080eb75 py3: convert arguments, cwd and env to native strings when
  spawning subprocess
* 876494fd967d cleanup: delete lots of unused local variables
* 57264906a996 watchman: add the possibility to set the exact watchman
  binary location

The newly-vendored code has support for specifying the binary location,
so 57264906a996 does not need applied. But we do need to modify our
code to specify a proper argument name.

876494fd967d is not important, so it will be ignored.

c31ce080eb75 globally changed the code base to always pass
str to subprocess. But pywatchman's code is Python 3 clean, so
we don't need to do this.

This leaves dd35abc409ee and b1f62cd39b5c, which will be re-applied in
subsequent commits.

Differential Revision: https://phab.mercurial-scm.org/D7201

== New Features ==

 * The amend extension supports the `--currentuser` argument.

 * The amend extension supports the `--close-branch` argument.

 * The amend extension supports the `--secret` argument.

 * The uncommit extension supports the `rewrite.update-timestamp` config option.

== New Experimental Features ==


== Bug Fixes  ==


== Backwards Compatibility Changes ==

 * A shell that supports `$(command)`` syntax for command substitution is now
   required for running the test suite. The test runner normally uses
   `sh`, so if that is a shell that doesn't support `$(command)` syntax,
   you can override it by setting `$HGTEST_SHELL` or by passing it to
   `run-tests.py --shell <shell>`.

 * The (experimental) narrow extension's wire protocol changed. If
   you're using it, you'll need to make sure to upgrade server and
   client at the same time.

== Internal API Changes ==
