mach_exception_data_type_t is more generic and is used for any element
of a codes[] array. For individual elements, the typedefs
mach_exception_code_t and mach_exception_subcode_t are available. Using
mach_exception_code_t when possible gives slightly more descriptive
code.
No functional change.

catch_exception_tool catches Mach exceptions. Currenlty, it simply
prints a message with some information about each exception it handles.
In the future, it will be tied to the minidump generator as well.

library support.
When building with support for Mac OS X 10.6, C++11 library support is
not available, because Mac OS X uses libc++ for C++11 support, and Mac
OS X 10.6 does not provide libc++ as a runtime library. gtest and gmock
have a hard time distinguishing between C++11 language and library
support (which is not really their fault, having one but not the other
is an odd situation). The currently-released trunk versions of gtest and
gmock do not work in this configuration. I’ve submitted patches upstream
to fix this, but they may take a while to make it to the released
verions. For now, it’s fine to roll gtest and gmock back to versions
from December 2013 that do work cleanly with C++11 language support but
only C++03 library support.

until the server is done handling its request.
In most tests, this is handled automatically because the client expects
a reply from the server, and waits for this reply. This test is
different because the server does handle the message, but does not send
a reply, so the client does not wait for one. When the child process
exits before the parent has had a chance to inspect the message it
received, the parent will find a dead name where it expects the remote
port to be, causing this test to be flaky based on the outcome of this
race.
The potential for a similar race existed in the
MachMessageServer.ComplexNotDestroyedNoReply test because it also
involved a request without a reply. In that test, the situation was
handled by not allowing the child to exit until signaled to do so by the
parent. The same logic should be used for both no-reply tests.

Kernel bugs prevent debug thread state flavors from being delivered to
exception handlers properly. Through luck, things work out for
x86_DEBUG_STATE and x86_DEBUG_STATE64, but a handler registered to
receive the x86_DEBUG_STATE32 thread state flavor will never be called.
For the x86 family, the only thread state flavors that can be delivered
to exception handlers are the thread, float, and exception flavors.

getsectionbyname() and getsegmentbyname() do not exist prior to Mac OS X
10.7. These functions are used by util_test MachOImageReader.*. For 10.6
SDK and runtime compatibility, Crashpad needs its own implementations of
these functions.
This checkin contains unmodified copies of the upstream code. A
subsequent checkin will contain the local modifications, which will trim
out all unnecessary portions. This is being committed in two parts to
make it easier to see what changes are being made to the upstream files.

MachOImageSymbolTableReader.
This results in a speed boost for MachOImageSymbolTableReader because
it’s able to read the entire string table in one operation, rather than
reading each string from the remote process individually. Copying is
also reduced. In a debug-mode build on my laptop, util_test
MachOImageReader.* has improved from ~1400ms to ~1000ms.

There’s no reason that “in” or “request” messages should be non-const.
This makes them const, bridges the const gap left by the MIG-generated
“check” functions with wrappers, and uses non-const fields in
“out” messages instead of const fields in “in” messages for in-out
parameters.

mach_exc is necessary because libSystem doesn’t contain this at all. exc
is necessary too, however: the copy in libSystem relies on the server
callbacks being externally defined symbols, which is cheesey.
Additionally, some Crashpad code wants to call internal validation
(“check”) routines that are not normally accessible to outside callers
via the copy of exc in libSystem, but they are made accessible here by
processing mig’s output in this Python script.

This adds a pipe going in the other direction (parent to child).
Initially, I didn’t think this was necessary, but it turned out to be
needed for ProcessReader. Having the child wait on a pipe read is the
easiest way to keep it alive until the parent is done with it.
This also tests MachMultiprocess::ChildPID() in
mach_multiprocess_test.cc.

time_t is a typedef for long on Mac OS X. In 32-bit x86 (ILP32), long is
a signed 32-bit quantity, and its range does not contain the range of
uint32_t, used to store times in time_t fashion in minidump files. A
cast is necessary to make these EXPECT_* macros do the right thing. This
is not a problem in x86_64 (LP64) where long is a signed 64-bit
quantity, which does contain the range of uint32_t.
clang’s error was “error: comparison of integers of different signs:
'const long' and 'const unsigned int' [-Werror,-Wsign-compare]”
