Some applications want to use low priority realtime signals (e.g., SIGRTMAX). Currently QEMU cannot map all target realtime signals to host realtime signals, and chooses to sacrifice the end of the target realtime signal range. Allow users to choose how to map target realtime signals to host realtime signals using the new -t option, the new QEMU_RTSIG_MAP environment variable, and the new -Drtsig_map=\"...\" meson flag. To simplify things, the meson flag is not per-target, because the intended use case is app-specific qemu-user builds. The mapping is specified using the "tsig hsig count[,...]" syntax. Target realtime signals [tsig,tsig+count) are mapped to host realtime signals [hsig,hsig+count). Care is taken to avoid double and out-of-range mappings.
