bc5b7b06db Fix racy WorkerThread test
WorkDelegate::DoWork() can be called more times than the value set by
WorkDelegate::SetDesiredWorkCount(). The main test thread may not be
able to “squeeze” its call to WorkerThread::Stop() in after its
WorkDelegate::WaitForWorkCount() returns. If the worker thread cannot be
stopped in time, one or more additional iterations of
WorkDelegate::DoWork() can run. WorkDelegate::DoWork() should take care
to not increment work_count_ beyond the desired value.

Bug: crashpad:169
Test: crashpad_util_test WorkerThread.*

f34ed66b93 metrics: Record handler lifetime milestone events
It could be useful to put our existing Crashpad.HandlerCrashed metrics
into context by getting a sense of handler starts, clean exits, and
other types of exits.

f735d050c4 Port the util library to Linux
With this change, it is possible to build crashpad_util on Linux. I
built with clang 3.8.1 and GCC 6.2.0.

 - For per-OS “exception code” metrics, Android and Linux are broken out
   distinctly.
 - Because Linux provides no standard UUID generator, base::RandBytes()
   is used to generate random UUIDs for the InitializeWithNew() form.
 - Multiple fixes for CloseMultipleNowOrOnExec():
    - readdir_r() is deprecated in glibc 2.24. Use readdir() on Linux.
    - Linux does not have OPEN_MAX. Use the fs.nr_open sysctl (via
      /proc/sys) to determine the maximum (currently-configured)
      possible number of file descriptors per process.
    - Use the {CTL_KERN, KERN_MAXFILESPERPROC} sysctl on Mac to
      determine the maximum (currently-configured) possible number of
      file descriptors per process. This is an improvement over using
      OPEN_MAX, which is still consulted.
 - ThreadLogMessages’ use of DCHECK_EQ() needs an address-of operator on
   function pointers to avoid confusing GCC.

One problem remains:

 - util/misc/pdb_structures.h produces -Wmultichar errors. -Wmultichar
   is enabled by default with GCC (but not clang). It is impossible to
   disable this warning with #pragma GCC diagnostic ignored. See
   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53431

This has not been tested beyond building the crashpad_util target.

35da3b6735 Fix race in worker_thread_test.cc
The desired work count must be set before the thread is started,
otherwise multiple work items might be completed before it is set,
resulting it never signalling the sema.

6d2d31d2d1 Use base/macros.h instead of base/basictypes.h
This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.

This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.

e128dcf10122 Remove base/move.h; use std::move() instead of Pass()

809ea8158d test: Move util/test to its own top-level directory, test.
After 9e79ea1da719, it no longer makes sense for crashpad_util_test_lib
to “hide” in util/util_test.gyp. All of util/test is moved to its own
top-level directory, test, which all other test code is allowed to
depend on. test, too, is allowed to depend on all other non-test code.

In a future change, when crashpad_util_test_lib gains a dependency on
crashpad_client, it won’t look so weird for something in util (even
though it’s in util/test) to depend on something in client, because the
thing that needs to depend on client will live in test, not util.
