This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.
#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.

ExceptionHandlerServer::keep_running_ is used to implement
synchronization across threads (e.g. ExceptionHandlerServer::Stop)
but the variable is not atomic. This causes TSan failures and could
also lead to incorrect compiler optimizations.

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.

Multi client socket connections allow multiple clients to request crash
dumps from a handler process using a single, shared socket connection.
This connection mode does not support using a broker process which
requires a dedicated socket connection to ensure handler messages
aren't intercepted by the wrong clients.
The handler uses SIGCONT to indicate to the crasher when a crash dump
is complete (or has failed) and may continue.

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.

Sanitization is controlled by a SanitizationInformation struct to be
read from the client's memory. The address of this struct is either
passed in a ClientInformation when the client requests a crash dump,
or as a flag to the handler --sanitization_information.
