worker: rewrite error handling so os._exit covers all cases

Previously the worker error handling is like:

    pid = os.fork()   --+
    if pid == 0:        |
        ....            | problematic
        ....          --+
        try:          --+
            ....        | worker error handling
                      --+

If a signal arrives when Python is executing the "problematic" lines, an
external error handling (dispatch.py) will take over the control flow and
it's no longer guaranteed "os._exit" is called (see 86cd09bc13ba for why it
is necessary).

This patch rewrites the error handling so it covers all possible code paths
for a worker even during fork.

Note: "os.getpid() == parentpid" is used to test if the process is parent or
not intentionally, instead of checking "pid", because "pid = os.fork()" may
be not atomic - it's possible that that a signal hits the worker before the
assignment completes [1].  The newly added test replaces "os.fork" to
exercise that extreme case.

[1]: CPython compiles "pid = os.fork()" to 2 byte codes: "CALL_FUNCTION" and
"STORE_FAST", so it's probably not atomic:

    def f():
        pid = os.fork()

    dis.dis(f)
      2           0 LOAD_GLOBAL              0 (os)
                  3 LOAD_ATTR                1 (fork)
                  6 CALL_FUNCTION            0
                  9 STORE_FAST               0 (pid)
                 12 LOAD_CONST               0 (None)
                 15 RETURN_VALUE

This file contains testcases that tend to be related to special cases or less
common commands affecting largefile.

Each sections should be independent of each others.

test for pattern matching on 'hg status':
==============================================


to boost performance, largefiles checks whether specified patterns are
related to largefiles in working directory (NOT to STANDIN) or not.

  $ hg init statusmatch

  $ echo normal > a/b/c/d/e.normal.txt

  $ hg status -A
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt
  C a/b/c/x/y.normal.txt

(2) pattern not related to largefiles: performance boost
  $ hg status -A a/b/c/x
  C a/b/c/x/y.normal.txt

(3) pattern related to largefiles: no performance boost
  $ hg status -A a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt

(4) pattern related to STANDIN (not to largefiles): performance boost
  $ hg status -A .hglf/a
  C .hglf/a/b/c/d/e.large.txt

(5) mixed case: no performance boost
  $ hg status -A a/b/c/x a/b/c/d

Pushing revision #1 causes uploading entity 89e6c98d9288, which is
shared also by largefiles b1, b2 in revision #2 and b in revision #5.

Then, entity 89e6c98d9288 is not treated as "outgoing entity" at "hg
summary" and "hg outgoing", even though files in outgoing revision #2
and #5 refer it.
