Implement 'git fsmonitor--daemon start' command. This command starts
an instance of 'git fsmonitor--daemon run' in the background using
the new 'start_bg_command()' function.
We avoid the fork-and-call technique on Unix systems in favor of a
fork-and-exec technique. This gives us more uniform Trace2 child-*
events. It also makes our usage more consistent with Windows usage.
On Windows, teach 'git fsmonitor--daemon run' to optionally call
'FreeConsole()' to release handles to the inherited Win32 console
(despite being passed invalid handles for stdin/out/err). Without
this, command prompts and powershell terminal windows could hang
in "exit" until the last background child process exited or released
their Win32 console handle. (This was not seen with git-bash shells
because they don't have a Win32 console attached to them.)

Implement `run` command to try to begin listening for file system events.
This version defines the thread structure with a single fsmonitor_fs_listen
thread to watch for file system events and a simple IPC thread pool to
watch for connection from Git clients over a well-known named pipe or
Unix domain socket.
This commit does not actually do anything yet because the platform
backends are still just stubs.

Implement `stop` and `status` client commands to control and query the
status of a `fsmonitor--daemon` server process (and implicitly start a
server process if necessary).
Later commits will implement the actual server and monitor the file
system.

Create a built-in file system monitoring daemon that can be used by
the existing `fsmonitor` feature (protocol API and index extension)
to improve the performance of various Git commands, such as `status`.
The `fsmonitor--daemon` feature builds upon the `Simple IPC` API and
provides an alternative to hook access to existing fsmonitors such
as `watchman`.
This commit merely adds the new command without any functionality.

Document how `core.fsmonitor` can be set to a boolean to enable
or disable the builtin FSMonitor.
Update references to `core.fsmonitor` and `core.fsmonitorHookVersion` and
pointers to `Watchman` to refer to it.

Move fsmonitor config settings to a new and opaque
`struct fsmonitor_settings` structure. Add a lazily-loaded pointer
to this into `struct repo_settings`
Create an `enum fsmonitor_mode` type in `struct fsmonitor_settings` to
represent the state of fsmonitor. This lets us represent which, if
any, fsmonitor provider (hook or IPC) is enabled.
Create `fsm_settings__get_*()` getters to lazily look up fsmonitor-
related config settings.
Get rid of the `core_fsmonitor` global variable. Move the code to
lookup the existing `core.fsmonitor` config value into the fsmonitor
settings.
Create a hook pathname variable in `struct fsmonitor-settings` and
only set it when in hook mode.
Extend the definition of `core.fsmonitor` to be either a boolean
or a hook pathname. When true, the builtin FSMonitor is used.
When false or unset, no FSMonitor (neither builtin nor hook) is
used.
The existing `core_fsmonitor` global variable was used to store the
pathname to the fsmonitor hook *and* it was used as a boolean to see
if fsmonitor was enabled. This dual usage and global visibility leads
to confusion when we add the IPC-based provider. So lets hide the
details in fsmonitor-settings.c and let it decide which provider to
use in the case of multiple settings. This avoids cluttering up
repo-settings.c with these private details.
A future commit in builtin-fsmonitor series will add the ability to
disqualify worktrees for various reasons, such as being mounted from a
remote volume, where fsmonitor should not be started. Having the
config settings hidden in fsmonitor-settings.c allows such worktree
restrictions to override the config values used.

As part of our code of conduct, we maintain a list of active members on
the Project Leadership Committee, which serves a couple of purposes. The
details are in 3f9ef874a7 (CODE_OF_CONDUCT: mention individual
project-leader emails, 2019-09-26), but the gist is as follows:
- It makes it clear that people with a CoC complaint may contact
members individually as opposed to the general PLC list (in case the
subject of their complaint has to do with one of the committee
members).
- It also serves as the de-facto list of people on the PLC, which
isn't committed anywhere else in the tree.
As of [1], Peff is no longer a member of Git's Project Leadership
Committee. Let's update the list of active members accordingly [2].
This also gives us a convenient opportunity to thank Peff for his many
years of service on the PLC, during which he helped the Git community in
more ways than we can easily list here.
