2d87606bb5 win: Start crashpad_handler by inheriting connection data to it
Previously, StartHandler() launched the handler process, then connected
over a pipe to register for crash handling. Instead, the initial client
can create and inherit handles to the handler and pass those handle
values and other data (addresses, etc.) on the command line.

This should improve startup time as there's no need to synchronize with
the process at startup, and allows avoiding a call to CreateProcess()
directly in StartHandler(), which is important for registration for
crash reporting from DllMain().

Incidentally adds new utility functions for string/number conversion and
string splitting.

Note: API change; UseHandler() is removed for all platforms.

6d2d31d2d1 Use base/macros.h instead of base/basictypes.h
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()

583d1dc3ef Provide std::move() in compat instead of using crashpad::move()
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.

6bebb10829 Replace use of .Pass() with crashpad::move().
Since C++11 library support isn't available everywhere crashpad is
compiled, add our own move() method in the crashpad namespace to replace
std::move() for now. Replace uses of .Pass() with this method.

fc7d8b3a27 mac: Make crashpad_handler get its receive right from its client
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.

062138106c mac: ChildPortHandshake: allow receive rights to be sent
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.

6c0d42ce9d Mach port scopers should use get() instead of type conversion operators
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().

c95b30464a mac: Make UseSystemDefaultHandler() clear handlers on failure
If the task’s exception handler for EXC_CRASH, EXC_RESOURCE, and
EXC_GUARD exceptions cannot be set, clear the handler instead.

Nothing considered this function’s return value, and the only viable
fallback action on failure would have been to do what the function now
does, so its return type is changed to void.

cd85c9f700 mac: Add CrashpadClient::UseSystemDefaultHandler()
Chrome’s relauncher process needs a way to sever ties with the
crashpad_handler instance running from the disk image in order to cause
that instance to exit so that the disk image may be unmounted. This new
function is otherwise not thought to be interesting, and its use is not
recommended.

This comes with a small refactoring to create a
SystemCrashReporterHandler() function, and a fix for a minor port leak
in CrashReportExceptionHandler::CatchMachException().

9086d25ce8 Don’t trigger EXC_CORPSE_NOTIFY on OS X 10.11
CrashReportExceptionHandler::CatchMachException() must always set a
valid new_state. Failing to do so appears to trigger corpse generation
on OS X 10.11. This is addressed by calling ExcServerCopyState().
Previously, this was not done for exceptions forwarded to the user
ReportCrash, under the apparent mistaken assumption that ReportCrash
would do it. However, ReportCrash is given copies of out-parameters like
new_state to explicitly prevent it from influencing Crashpad’s returned
state.

ExcServerSuccessfulReturnValue() must not return MACH_RCV_PORT_DIED for
an EXC_CRASH handler on OS X 10.11. This appears to trigger corpse
generation. This is addressed by always returning KERN_SUCCESS from
EXC_CRASH handlers on OS X 10.11.

This also adds generic EXC_CORPSE_NOTIFY support throughout Crashpad.
The crashpad_handler does not listen for this exception type, but it is
now possible to work with this exception type using tools like
exception_port_tool and catch_exception_tool.

e1347a740c Handle EXC_RESOURCE and EXC_GUARD exceptions properly.
These two exception types use all 64 bits of the code[0] field.  The
ExceptionSnapshot was unprepared to stuff this into a 32-bit field.  To
resolve the discrepancy, the more-significant data is taken from the
high 32 bits of code[0]. No information is lost because the full code[0]
is made available as part of the Codes() vector.

CrashpadClient is the primary interface for an application to have
Crashpad monitor it for crashes. It contains StartHandler(), which
