In July I sent the V3 version [3] of my Builtin FSMonitor series [1,2,3].
This has been in "seen" as branch jh/builtin-fsmonitor. At 34 commits, it
was already a little too big to easily review. With the feed back on [3] and
from people using the experimental version that we shipped with
git-for-windows v2.32 and v2.33, I've prepared a new V4 version. This can be
seen in [4].

However, this new version currently contains 58 commits and is way too big
to be submitted as is. So I would like to close or discard the original V3
branch and submit V4 in pieces to make it easier to review.

Here is Part 1 of (what would be V4 of) my Builtin FSMonitor series.

Part 1 contains:

 * A fix for a memory leak in the Trace2 code. (This was independently
   reported in last week in "ab/tr2-leaks-and-fixes".)
 * Various cleanups in the simple-ipc layer.
 * A new start_bg_command() function to launch a command into the background
   and wait for it to start. And a refactored consumer of it in
   test-simple-ipc. There was a large discussion on commit 14/34 in V3 [5
   thru 6] about the large ifdef'd blocks of platform specific code to spawn
   background commands, trace2 handling, and duplicated code in
   fsmonitor--daemon.c and in test-simple-ipc. That has all been addressed
   here.
