server: add an error feedback mechanism for when the daemon fails to launch

There's a recurring problem on Windows where `hg serve -d` will randomly fail to
spawn a detached process.  The reason for the failure is completely hidden, and
it takes hours to get a single failure on my laptop.  All this does is redirect
stdout/stderr of the child to a file until the lock file is freed, and then the
parent dumps it out if it fails to spawn.

I chose to put the output into the lock file because that is always cleaned up.
There's no way to report errors after that anyway.  On Windows, killdaemons.py
is roughly `kill -9`, so this ensures that junk won't pile up.

This may end up being a case of EADDRINUSE.  At least that's what I saw spit out
a few times (among other odd errors and missing output on Windows).  But I also
managed to get the same thing on Fedora 26 by running test-hgwebdir.t with
--loop -j10 for several hours.  Running `netstat` immediately after killing that
run printed a wall of sockets in the TIME_WAIT state, which were gone a couple
seconds later.  I couldn't match up ports that failed, because --loop doesn't
print out the message about the port that was used.  So maybe the fix is to
rotate the use of HGPORT[12] in the tests.  But, let's collect some more data
first.

Create test repository:

  $ hg init repo
  $ cd repo
  $ echo x1 > x.txt

  $ hg init foo
  $ cd foo
  $ echo y1 > y.txt

  $ hg init bar
  $ cd bar
  $ echo z1 > z.txt

  $ cd ..
  $ echo 'bar = bar' > .hgsub

  $ cd ..
  $ echo 'foo = foo' > .hgsub

Add files --- .hgsub files must go first to trigger subrepos:

  $ hg add -S .hgsub
  $ hg add -S foo/.hgsub
  $ hg add -S foo/bar
  adding foo/bar/z.txt
  $ hg add -S
  adding x.txt
  adding foo/y.txt

Test recursive status without committing anything:

  $ hg status -S
  A .hgsub
  A foo/.hgsub
  A foo/bar/z.txt
  A foo/y.txt
  A x.txt

Test recursive diff without committing anything:

  $ hg diff --nodates -S foo
  diff -r 000000000000 foo/.hgsub
  --- /dev/null
  +++ b/foo/.hgsub
  @@ -0,0 +1,1 @@

Commits:

  $ hg commit -m fails
  abort: uncommitted changes in subrepository "foo"
  (use --subrepos for recursive commit)
  [255]

The --subrepos flag overwrite the config setting:

  $ hg commit -m 0-0-0 --config ui.commitsubrepos=No --subrepos
  committing subrepository foo
  committing subrepository foo/bar

  $ cd foo
  $ echo y2 >> y.txt
  $ hg commit -m 0-1-0

  $ echo z2 >> z.txt
  $ hg commit -m 0-1-1

  $ cd ..
  $ hg commit -m 0-2-1

Note there's a slight output glitch on non-hardlink systems: the last
"linking" progress topic never gets closed, leading to slight output corruption on that platform.

Archive + subrepos uses '/' for all component separators

  $ tar -tzf ../archive.tar.gz | sort
  .hg_archival.txt
  .hgsub
  .hgsubstate
  foo/.hgsub
  foo/.hgsubstate
  foo/bar/z.txt
  foo/y.txt
  x.txt

The newly cloned subrepos contain no working copy:

  $ hg -R foo summary
  parent: -1:000000000000  (no revision checked out)
  branch: default
  commit: (clean)
  update: 4 new changesets (update)

Sharing a local repo without the locally referenced subrepo (i.e. it was never
updated from null), fails the same as a clone operation.

  $ hg --config progress.disable=True clone -U ../empty ../empty2

  $ hg --config extensions.share= --config progress.disable=True \
  >    share ../empty2 ../empty_share
  updating working directory
  abort: repository $TESTTMP/empty2/foo not found!
  [255]

  $ hg --config progress.disable=True clone ../empty2 ../empty_clone
  updating to branch default
  abort: repository $TESTTMP/empty2/foo not found!
  [255]

Disable progress extension and cleanup:

  $ mv $HGRCPATH.no-progress $HGRCPATH

Test archiving when there is a directory in the way for a subrepo
created by archive:

  $ hg clone -U . ../almost-empty
  $ cd ../almost-empty
  $ mkdir foo
  $ echo f > foo/f
  $ hg archive --subrepos -r tip archive
  cloning subrepo foo from $TESTTMP/empty/foo
  abort: destination '$TESTTMP/almost-empty/foo' is not empty (in subrepository "foo")
  [255]

Clone and test outgoing:

  $ cd ..
  $ hg clone repo repo2
  updating to branch default
  cloning subrepo foo from $TESTTMP/repo/foo
  cloning subrepo foo/bar from $TESTTMP/repo/foo/bar
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
