c25a5e670b init: Signal m_tip_block_cv on Ctrl-C (Ryan Ofsky)
6a29f79006 test: Test SIGTERM handling during waitforblockheight call (Ryan Ofsky)
Pull request description:
Signal `m_tip_block_cv` when Ctrl-C is pressed or `SIGTERM` is received, the same way it is currently signaled when the `stop` RPC is called. This lets RPC calls like `waitforblockheight` and IPC calls like `waitTipChanged` be interrupted, instead of waiting for their original timeouts and delaying shutdown.
This issue was reported by plebhash in #33463. These hangs have been present since #30409. A similar bug was also fixed previously in Qt in #18452 and this PR simplifies that fix.
