James Phillips 6dd0835319 Makes the timeout behavior more intuitive.
Previously, it would try once "up to" the timeout, but in practice it would
just fall through. This modifies the behavior to block until the timeout has
been reached.

Michael S. Fischer 01ec256c7e lock.go: fix another race condition
The previous fix to `consul lock` (commit 6875e8d) didn't completely
eliminate the race that could occur if the lock was acquired around the
same time SIGTERM was received:  It was still possible for
Run() to spawn the process via startChild() after killChild() had
released the shared mutex.

Now, when SIGTERM is received, we acquire a mutex that prevents
spawning a new process and never release it.

We've tested this fix pretty thoroughly and believe it completely
resolves the issue.

Emil Hessman c8224b3f94 command: fix Windows build
Add a per GOOS implementation to send signals to PIDs
since syscall.Kill does not exist on Windows.

It will always send a SIGKILL on Windows since there
seems to be no POSIX compatible notion.

Fixes build on Windows.
