workers: handling exceptions in windows workers

This adds handling of exceptions from worker threads and resurfaces them as if the function ran without workers.
If any of the threads throws, the main thread kills all running threads giving them 5 sec to handle the interruption and raises the first exception received.

We don't have to join threads if is_alive() is false

Test Plan:
Ran multiple updates/enable/disable sparse profile and things worked well

Ran test on CentOS- all tests passing on @ passed here

Added a forged exception into the worker code and got it properly resurfaced and the rest of workers killed: P58642088

Pushing a bookmark should only push the changes required by that
bookmark, not all outgoing changes:
  $ hg clone http://localhost:$HGPORT/ addmarks
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 5 changesets with 5 changes to 3 files (+2 heads)
  2 new obsolescence markers
  new changesets 4e3505fd9583:c922c0139ca0
  updating to bookmark @
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd addmarks
  $ echo foo > foo
  $ hg add foo
  $ hg commit -m 'add foo'
  $ echo bar > bar
  $ hg add bar
  $ hg commit -m 'add bar'
  $ hg co "tip^"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  (leaving bookmark @)
  $ hg book add-foo
  $ hg book -r tip add-bar
Note: this push *must* push only a single changeset, as that's the point
of this test.
  $ hg push -B add-foo --traceback

pushing a new bookmark on a new head does not require -f if -B is specified

  $ hg up -q X
  $ hg book W
  $ echo c5 > f2
  $ hg ci -Am5
  created new head
  $ hg push -B .

  $ hg -R ../b id -r W
  cc978a373a53 tip W

pushing an existing but divergent bookmark with -B still requires -f

  $ hg clone -q . ../r
  $ hg up -q X
  $ echo 1 > f2
  $ hg ci -qAml

  $ cd ../r
  $ hg up -q X

Check summary output for incoming/outgoing bookmarks

  $ hg bookmarks -d X
  $ hg bookmarks -d Y
  $ hg summary --remote | grep '^remote:'
  remote: *, 2 incoming bookmarks, 1 outgoing bookmarks (glob)

  $ cd ..

pushing an unchanged bookmark should result in no changes

  $ hg init unchanged-a
  $ hg init unchanged-b
  $ cd unchanged-a
  $ echo initial > foo
  $ hg commit -A -m initial
  adding foo
  $ hg bookmark @
  $ hg push -B @ ../unchanged-b
