From cl/304219049:
Optimize C++11 range-based for loops where the variable is copied in
each iteration but it would suffice to obtain it by const reference.
This is only applied to loop variables of types that are expensive to
copy which means they are not trivially copyable or have a non-trivial
copy constructor or destructor.
To ensure that it is safe to replace the copy with a const reference,
the following heuristic is employed:
- The loop variable is const qualified.
- The loop variable is not const, but only const methods or operators
are invoked on it, or it is used as const reference or value argument
in constructors or function calls.

sendmsg() and recvmsg() are complicated to use. Refactor their usage
into functions with a simpler, tested interface and use those instead.
This also adds CreateCredentialSocketpair() to create a pair of
connected sockets with SO_PASSCRED set. This option should be set
before the possibility of any calls to sendmsg() with the socket pair
to avoid race conditions in properly setting credentials.
Also update the handler to use Strategy::kNoPtrace (which causes the
crash dump to fail without breaking the socket connection) if the
credentials were invalid, which can happen if SO_PASSCRED was set after
the call to sendmsg() or if the sending process does not exist in this
namespace.

When a crashing process is in a different PID namespace than the
handler, the crasher doesn't have a way of knowing its own thread ID in
the handler's namespace and the kernel lacks mechanisms to perform this
translation before Linux 4.1 (where the information is present in
/proc/<pid>/status:NSPid).
This patch gives the handler a way of identifying the requesting thread
by sending a stack address along with the crash dump request, which
the handler can search for in each of the process' threads.
This information is useful both for attaching exception information
to the right thread and to allow the handler to send signals to the
correct thread when using a shared socket connection.

In any case, suspending in HandleExceptionHandles() is fine, the thread
for the exception will be suspended on entry, so suspending other
threads after the initial excepting thread's koid to handle lookup is
OK.
This avoids a bunch of logspam like:
zx_thread_read_state(ZX_THREAD_STATE_GENERAL_REGS): ZX_ERR_BAD_STATE (-20)
