An expectation of the child’s termination reason can now be specified.
It is now possible to test with children that do not exit cleanly, if
they are not expected to exit cleanly.

This also adds a COMPILE_ASSERT to check that the
PersistentNonblockingFourMessages test case is not exceeding the value
of MACH_PORT_QLIMIT_DEFAULT.

MachMessageServer is much like mach_msg_server() and
mach_msg_server_once(), but with a C++ interface and with a number of
deficiencies corrected.

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 is part of a family of classes whose chief entry point is
MachOImageReader. MachOImageReader depends on this class to read
segments, so this one is landing first. The bulk of this class will be
tested as part of MachOImageReader.

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.
Both of these fell out of https://codereview.chromium.org/491963002/.

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]”

InRangeCast<> is similar to base::saturated_cast<>, but it allows the
caller to specify the value to be returned in the event that the source
value can’t be converted to the destination data type without data loss.

MinidumpFileWriter writes the top-level object to a minidump file. This
consists of a MINIDUMP_HEADER and a list of MINIDUMP_DIRECTORY entries
that point to streams, which are second-level objects in minidump files.
This change also adds the base class for stream writers,
MinidumpStreamWriter.
