reuses the functionality of PEImageAnnotationsReader.

a43fee120b10 Sync Mac scopers with upstream Chromium
This adapts to updated Mac scopers from Chromium cfd6ed5600d8, including
the changes from that commit and Chromium f39d4ffc6c32.

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()

Fix some warnings when compiling crashpad with VC++ 2015 Update 1.
Warning 4302 occurs if you convert from a pointer to a <sizeof(void*)
integer in one cast, because this often indicates an accidental pointer
truncation which can be a bug in 64-bit builds.
Warning 4577 warns that noexcept will not be enforced, but we don't want
it to be enforced anyway, so I disabled it. The full warning is:
warning C4577: 'noexcept' used with no exception handling mode specified
termination on exception is not guaranteed. Specify /EHsc

Patch from Bruce Dawson <brucedawson@chromium.org>.
This more-natural spelling doesn’t require Crashpad developers to have
to remember anything special when writing code in Crashpad. It’s easier
to grep for and it’s easier to remove the “compat” part when pre-C++11
libraries are no longer relevant.

MEMORY_BASIC_INFORMATION64 specifies an alignment of 16, but the
standard allocator used by containers doesn't honor this. Although 16
is the default alignment size used on Windows for x86_64, it's not for
32-bit x86. clang assumed that the alignment of the structure was as
declared, and used an SSE load sequence that required this alignment.
AlignedAllocator is a replacement for std::allocator that allows the
alignment to be specified. AlignedVector is an std::vector<> that uses
AlignedAllocator instead of std::allocator.

Don't call GetFileVersionInfo(), which calls LoadLibrary() to be able to
access the module's resources. Loading modules from the crashy process
into the handler process can cause trouble. The Crashpad handler
definitely doesn't want to run arbitrary modules' module initializer
code.
Since the VS_FIXEDFILEINFO needed is already in memory in the remote
process' address space, just access it from there.

The bug and linked code review has more of the history, but we’ve been
tempted to remove the loop outright a couple of times already before
realizing that it serves an important purpose. Hopefully this comment
will protect our future selves from going on the same fool’s errand.

In 2eeaa3ac549a, I added a check to make sure that the expected CONOUT$
handle was found. Its omission seemed to be unintentional. The tests
passed for me on Windows 10, but failed on the bots. I can reproduce
the failures locally on Windows 7.
Doing the inheritance test with a file other than CONOUT$ fixes the
immediate problem, but we should find out why this CONOUT$ handle isn't
showing up in the handles list on Windows 7, fix it, and add back a
test.

Allowing the client to create its own pipe name string caused a race
between client and server. Instead, in this mode, the server now creates
the pipe name along with a pipe, and returns it to its client via a
--handshake-handle. This guarantees that by the time the client gets the
pipe name, the server has already created it.
Ephemeral mode is now implied by --handshake-handle. The --persistent
option is gone. --persistent mode is enabled when using --pipe-name.

I considered writing the CodeView records to the minidump, but I didn't
find a ton of docs and debugging is only lightly supported (e.g.
http://www.debuginfo.com/articles/gendebuginfo.html#debuggersandformats
and it doesn't attempt to load at all on more recent Visual Studios).
As we won't be generating symbols in this format, and we don't expect to
have symbols for any weird modules that get injected into us in the
wild, it seems like we don't lose anything by just ignoring them.

Each routine in this implementation returns MIG_BAD_ID. These routines
may be overridden.
Most things that implement NotifyServer::Interface will only need to
implement one of the interface routines. Since another user of
NotifyServer will be added soon, it makes sense to provide a default
no-op implementation rather than forcing everyone to write the same
no-op boilerplate repeatedly.

Previously, crashpad_handler made its own receive right, and transferred
a corresponding send right to its client. There are two advantages to
making the receive right in the client:
- It is possible to monitor the receive right for a port-destroyed
notificaiton in the client, allowing the handler to be restarted if
it dies.
- For the future run-from-launchd mode (bug crashpad:25), the handler
will obtain its receive right from the bootstrap server instead of
making its own. Having the handler get its receive right from
different sources allows more code to be shared than if it were to
sometimes get a receive right and sometimes make a receive right and
transfer a send right.
This includes a restructuring in crashpad_client_mac.cc that will make
it easier to give it an option to restart crashpad_handler if it dies.
The handler starting logic should all behave the same as before.

This allows better code sharing in crashpad_handler’s main(). It doesn’t
look like much of an improvement now, but a separate change will cause
the Mac ExceptionHandlerServer() to be constructed with an argument. It
will be beneficial for Mac and Windows to be able to share the Run()
call.

The intended use is to flip the client-server relationship in
CrashpadClient so that the initial client (parent process) furnishes the
handler process with a receive right. The parent can optionally receive
a port-destroyed notification allowing it to restart the handler if it
exits prematurely.

Fixes two incorrect usages of ssize_t/off_t being implicitly converted

BOOL returning Win32 functions.

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().
