When running plugin tests it's not uncommon to see:
vcpu 0 has internal error
Though the tests don't actually fail on this problem. This seems
to occur as a side effect of the plugin_vcpu_pause.c calling
crosvm_destory_memory() before the test VM has actually finished
running.
The main thread will call read() on the 'kill' eventfd 5 times for:
init, pause, unpause, unpause, kill
The vcpu thread will call write() on the eventfd up to 8 times:
init, pause #1, unpause #1, pause #2, unpause #2, pause #3,
unpause #3, kill
The main thread's third pause request might occur before the second
pause request has been processed, in which case the vcpu thread will
only be paused twice (thus there will only be 6 calls to write()).
Given the unpredictable # of events I've opted to split the
init/pause/unpause events to a separate eventfd and keep the 'kill'
eventfd solely for its intended purpose.
BUG=None
TEST=ran ./build_test several times and observed no failures in the
pause plugin test.

To ensure that we do not miss pause request sent while we were in paused
state, or were exiting paused state, let's start using
KVM_SET_SIGNAL_MASK. SIGRTMIN() + 0 signal will be blocked and thus is
not delivered, and it will only be checked when KVM_RUN is being
executed, reliably interrupting KVM_RUN.

We may want to issue additional crosvm_pause_vcpu() requests while VCPUs
are waiting to be resumed, so we need to make sure we are not holding
lock while waiting.
