Shutdown requests are normally hardware dependent.
By extending pvpanic to also handle shutdown requests, guests can
submit such requests with an easily implementable and cross-platform
mechanism.

The different components of pvpanic duplicate the list of supported
events. Move it to the shared header file to minimize changes when new
events are added.

Prepare for the removal from the Linux UAPI headers by moving the
contents to the existing pvpanic.h header.

linux-user/elfload: test return value of getrlimit
A process can opt-out of coredump creation by calling
prctl(PR_SET_DUMPABLE, 0).
linux-user passes this call from the guest through to the
operating system.
>From there it can be read back again to avoid creating coredumps from
qemu-user itself if the guest chose so.
