base::size, and std::size that will eventually replace it when C++17 is
assured, does not allow the size of non-static data members to be taken
in constant expression context. The remaining uses of ArraySize are in:
minidump/minidump_exception_writer.cc (×1)
minidump/minidump_system_info_writer.cc (×2, also uses base::size)
snapshot/cpu_context.cc (×4, also uses base::size)
util/misc/arraysize_test.cc (×10, of course)
The first of these occurs when initializing a constexpr variable. All
others are in expressions used with static_assert.

This uses “static” at function scope to avoid making local copies, even
in cases where the compiler can’t see that the local copy is
unnecessary. “constexpr” adds additional safety in that it prevents
global state from being initialized from any runtime dependencies, which
would be undesirable.
At namespace scope, “constexpr” is also used where appropriate.
For the most part, this was a mechanical transformation for things
matching '(^| )const [^=]*\['.
Similar transformations could be applied to non-arrays in some cases,
but there’s limited practical impact in most non-array cases relative to
arrays, there are far more use sites, and much more manual intervention
would be required.

- In the ProcessInfo test, port the global argc/argv getter to Linux by
reading /proc/self/cmdline.
- Use <inttypes.h> format macros for 64-bit types.
- Only #include <sys/sysctl.h> on macOS.
- #include <signal.h> instead of <sys/signal.h>.
In order to test on Linux/Android, the following changes to the
crashpad_util_test target must be made until more porting is complete:
- Remove the dependency on crashpad_client because that library has not
been ported yet.
- Remove process_info_test.cc because it depends on crashpad_client and
there is no implementation of ProcessInfo for Linux yet.
- Remove http_transport_test.cc because there is no HTTPTransport
implementation for Linux or Android yet.
- Remove checked_address_range_test.cc because checked_address_range.cc
does not yet expose a cross-bit usable type for addresses and sizes
on Linux.

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.

implicit_cast<> only performs a cast in cases where an implicit
conversion would be possible. It’s even safer than static_cast<> It’s an
“explicit implicit” cast, which is not normally necsesary, but is
frequently required when working with the ?: operator, functions like
std::min() and std::max(), and logging and testing macros.
The public style guide does not mention implicit_cast<> only because it
is not part of the standard library, but would otherwise require it in
these situations. Since base does provide implicit_cast<>, it should be
used whenever possible.
The only uses of static_cast<> not converted to implicit_cast<> are
those that require static_cast<>, such as those that assign an integer
constant to a variable of an enum type.

Even with the slop, this wound up being flaky, specifically on virtual

This includes ClockMonotonicNanoseconds() and SleepNanoseconds().
SleepNanoseconds() is like base::PlatformThread::Sleep(), but
PlatformThread is not in mini_chromium and I’m not keen on adding it
because I’m not sold on the interface. I’m not convinced Sleep() belongs
there, and I don’t want to have to bring all of base::Time* along for
the ride.
