3965bc7d78 Refactor OS_LINUX usage for coming LaCrOs update.
We're working to decouple ChromeOS and Linux builds of Chrome.

Currently OS_CHROMEOS sets OS_LINUX, so we need to refactor
current OS_LINUX usage to make this explicit.

Implemented the AddAttachment(), InitializeAttachments(), CleanDatabase() functions

On crash it will create the corresponding attachments in the database

c82309f0e5 fuchsia: Implement StartHandler() and ExceptionHandlerServer
StartHandler() binds to the default job's exception port, and launches
the handler process (normally this is crashpad_handler), passing it the
task handle and a handle to the exception port as startup parameters.
This follows the protocol used by crashlogger.

Additionally, implement ExceptionHandlerServer in crashpad_handler,
which contains the exception processing loop. It currently dispatches to
an empty CrashReportExceptionHandler where a report will be written
eventually.

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.

6a6a0c27ed win: Support dumping another process by causing it to crash
Adds a new client API which allows causing an exception in another
process. This is accomplished by injecting a thread that calls
RaiseException(). A special exception code is used that indicates to the
handler that the exception arguments contain a thread id and exception
code, which are in turn used to fabricate an exception record. This is
so that the API can allow the client to "blame" a particular thread in
the target process.

The target process must also be a registered Crashpad client, as the
normal exception mechanism is used to handle the exception.

The injection of a thread is used instead of DebugBreakProcess() which
does not cause the UnhandledExceptionFilter() to be executed.
NtCreateThreadEx() is used in lieu of CreateRemoteThread() as it allows
passing of a flag which avoids calling DllMain()s. This is necessary to
allow thread creation to succeed even when the target process is
deadlocked on the loader lock.

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,

dd3c20667d crashpad client for windows
Introduces CrashpadClient::SetHandler()

The code in the cc plays it fast and loose but helps ground
the intention.

29cdc74579 CrashpadClient::StartHandler(): accept database, url, and annotations arguments.
This makes it easier for clients to start the Crashpad handler, instead
of requiring them to know how to construct arguments for the handler
themselves. Note in the TEST that -a is no longer required.

2602e9d5d0 Add CrashpadClient.
CrashpadClient is the primary interface for an application to have
Crashpad monitor it for crashes. It contains StartHandler(), which
starts a Crashpad handler process, and UseHandler(), which configures
the process to direct its crashes to a handler process.
