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 10.12 SDK, x86_state_hdr from <mach/i386/thread_status.h> was
defined as:
struct x86_state_hdr {
int flavor;
int count;
};
This has changed in the 10.13 SDK to:
struct x86_state_hdr {
uint32_t flavor;
uint32_t count;
};
This triggers signedness mismatch errors where these values are used
with CHECK/DCHECK macros and gtest EXPECT/ASSERT macros.
Compatibility with existing and new SDKs must be maintained, so more
casts must be used.

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.
e128dcf10122 Remove base/move.h; use std::move() instead of Pass()

In https://codereview.chromium.org/1411523006, the Mach port scopers are
becoming better ScopedGenerics and are losing the type conversion
operators in the process. This is needed to adapt to that change. get()
is ugly, but being explicit about conversion isn’t a bad thing, and
these scopers will gain functionality such as Pass() as part of the
switch.
As a bonus, some would-be uses of get() to check for valid port rights
are becoming a more descriptive is_valid().

ExceptionPorts::GetExceptionPorts() returned a
std::vector<ExceptionPorts::ExceptionHandler>, which contained send
rights to Mach ports. The interface required callers to assume ownership
of each send right contained within the vector. This was cumbersome and
error-prone, and despite the care taken in Crashpad, port right leaks
did occur:
- SimulateCrash() didn’t make any attempt to release these resources at
all.
- Neither did crashpad_util_test ExceptionPorts.HostExceptionPorts,
which also reused a vector.
This replaces the vector with the interface-compatible (as far as
necessary) ExceptionPorts::ExceptionHandlerVector, which deallocates
collected port rights on destruction or clear().

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.
