OS X 10.11 introduces System Integrity Protection. One facet of that
forbids code injection into system executables. A Crashpad test checks
that information can be recovered from dyld in early-launch crashes by
requesting dyld load a nonexistent library with DYLD_INSERT_LIBRARIES.
The executable was meaningless but a system-provided executable,
/usr/bin/true, was used for convenience.
This test hung on OS X 10.11 because DYLD_INSERT_LIBRARIES was ignored
for the system executable, and no crash occurred. The test waited for a
crash that would never come.
A custom no-op executable, crashpad_snapshot_test_no_op, is provided as
an executable that does work with DYLD_INSERT_LIBRARIES.

The main goal was to get the beginnings of module iteration and retrieval
of CrashpadInfo in snapshot. The main change for that is to move
crashpad_info_client_options[_test] down out of mac/.
This also requires adding some of the supporting code of snapshot in
ProcessReaderWin, ProcessSnapshotWin, and ModuleSnapshotWin. These are
partially copied from Mac or stubbed out with lots of TODO annotations.
This is a bit unfortunate, but seemed like the most productive way to
make progress incrementally. That is, it's mostly placeholder at the
moment, but hopefully has the right shape for things to come.

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.

In a future change, crashpad_util_test_lib will gain a dependency on
crashpad_client. This would violate GYP’s prohibition on circular
dependencies between .gyp files, although there would be no circular
relationship between the targets themselves. To overcome this problem,
all test-related targets are moved into their own first-class .gyp
files.
