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.

This adds AuditPIDFromMachMessageTrailer() to get the process ID of a
Mach message’s sender. Exception messages are considered suspicious when
not sent by the kernel or the exception process.

optimization.
Newer versions of clang (in this case, trunk r231191) can see through
the pointless division by zero and optimize it away. This caused the
test to hang in release mode.
A 50ms timeout is added to each test to transform the hang into a
failure. The test was split into 12 tests to provide better feedback and
control.
To fix the bug, the division by zero is replaced by __builtin_trap().

- Various "FD" to "Handle"
- Existing Multiprocess implementation moves to _posix.
- Stub implementation for _win.
At the moment, multiprocess_exec_win.cc contains implementations of both
Multiprocess methods and MultiprocessExec functions. This will need more
work in the future, but reflects the idea that all tests should be in
terms of MultiprocessExec eventually.
Currently, this works sufficiently to have util_test succeed (including
multiprocess_exec_test, and the recently ported HTTPTransport tests.)

Rename fd_io to file_io, and ReadFD to ReadFile, etc.
file_io.cc is the higher level versions that call the basic ReadFile/WriteFile
and then file_io_posix.cc and file_io_win.cc are the implementations of
those functions.
The Windows path is as yet untested, lacking the ability to link the test binary.

MachMessageServer::Run()’s distinct |nonblocking| parameter is removed.
The information it formerly conveyed is now implied by the |timeout_ms|
parameter, which can accept two special values,
kMachMessageTimeoutNonblocking and kMachMessageTimeoutWaitIndefinitely.

UniversalMachExcServer provided both an interface and an implementation,
contrary to the other classes in the exc_server_variants family. This
was mostly done for reasons of economy in an already-large class family.
Unfortunately, this decision meant that it was impossible for other code
to use UniversalMachExcServer, which required that CatchMachException()
be implemented, and also extend another class without violating the
style guide’s prohibition of multiple implementation inheritance. This
became a problem in a lot of test code, which extended MachMultiprocess
and UniversalMachExcServer.
UniversalMachExcServer is now given its own nested Interface class,
which is a pure interface. All users of UniversalMachExcServer are
changed from “is-a” UniversalMachExcServer to “has-a”
UniversalMachExcServer and “is-a” UniversalMachExcServer::Interface.

Previously, MachMessageServer::Run() only provided two strategies for
dealing with large messages, indicated by mach_msg() returning
MACH_RCV_TOO_LARGE: the receive buffer could be reallocated and the
message received, or the entire function could return MACH_RCV_TOO_LARGE
to the caller. There are situations where an intermediate behavior might
be desirable. This intermediate behavior would allow the function to
continue waiting for another message without returning an error to the
caller or attempting to receive the large message. This is desirable
when dealing with fixed-sized messages and a receiver that might be sent
messages by unknown, possibly-malicious callers. This can happen when
the corresponding send right is published with the bootstrap server, for
example.
Existing users continue to request their existing behavior, typically
receiving an error when encountering a large message.
catch_exception_tool will use the new “ignore” behavior when running in
persistent mode.

This change was generated mechanically by running:
find . \( -name \*.cc -or -name \*.mm -or -name \*.h \) \
-and -not -path ./third_party/\* -and -not -path ./out/\* \
-exec sed -i '' -E -e 's/(^|[^_])NULL/\1nullptr/g' {} +
Further manual fix-ups were applied to remove casts of nullptr to other
pointer types where possible, to preserve the intentional use of NULL
(as a short form of MACH_PORT_NULL) in exception_port_tool, and to fix
80-column violations.

This uses THREAD_NULL, TASK_NULL, and HOST_NULL in preference to
MACH_PORT_NULL and kMachPortNull. These constants are correctly-typed
(thread_t, task_t, and host_t) and result in more readable source code,
especially where thread and task parameters appear together as they do
in exc_*_variants.
