Rollup merge of #133631 - flba-eb:add_nto_qnx71_iosock_support, r=workingjubilee
Support QNX 7.1 with `io-sock`+libstd and QNX 8.0 (`no_std` only) Changes of this pull request: 1. Refactor code for qnx nto targets to share more code in file `nto_qnx.rs` 1. Add support for an additional network stack on nto qnx 7.1. QNX 7.1 supports two network stacks: 1. `io-pkt`, which is default 2. `io-sock`, which is optional on 7.1 but default in QNX 8.0 As one can see in the [io-sock migration notes](https://www.qnx.com/developers/docs/7.1/index.html#com.qnx.doc.neutrino.io_sock/topic/migrate_app.html), this changes the libc API in a way similar to e.g. linux-gnu vs. linux-musl. This change adds a new target which has a different value for `target_env`, so that e.g. libc can distinguish between both APIs. 2. Add initial support for QNX 8.0, thanks to AkhilTThomas. As it turned out, the problem with forking many processes still exists in QNX 8.0. Because if this, we are now using it for any QNX version (i.e. not check for `target_env` anymore).
