bug 1344321 - remove linux64-pgo from target_tasks_mozilla_beta. r=dustin a=release MozReview-Commit-ID: AVai8RLFTVo

bug 1344321 - add nightly test support. r=dustin a=release this patch: - adds linux{32,64}-nightly/opt test platforms that mirror the non-nightly test platforms. - adds an `include_nightly` per-project parameter; this is refered to in the default `target_task_method`. It's still possible to launch custom `target_task_method`s to trigger nightlies against, say, try. - adds a `filter_for_project` method in `target_tasks.py` that allows for `include_nightly` and `run_on_projects` filtering in the various `target_task_method`s. - adds nightly filtering into the `TryOptionSyntax` object. By default, this will be off. To trigger nightly tests on try, either submit a new decision task with a different `target_task_method` (e.g. `nightly_fennec`) or flip the `include_nightly` flag to True. - adds the `nightly` attribute to tests if their builds have that attribute.

servo: Merge #15783 - Replace manual host parsing code with parse-host crate (from ferjm:issue15756-parse-hosts); r=avadacatavra This patch is replacing the code to parse the hosts file with the [parse-hosts](https://crates.io/crates/parse-hosts) crate. This crate has a [CC0 1.0 Universal License](https://creativecommons.org/publicdomain/zero/1.0/deed.en). I could have used [HostsFile::load()](https://clarcharr.github.io/parse-hosts/parse_hosts/struct.HostsFile.html#method.load) directly, but this method loads `/etc/hosts` by default and does not allow to override the default path (for example with [env::var("HOST_FILE")](https://dxr.mozilla.org/servo/source/components/net_traits/hosts.rs#19)), so I kept the existing code to open and read the content of `env::var("HOST_FILE")` and also kept the [parse_hostsfile](https://dxr.mozilla.org/servo/source/components/net_traits/hosts.rs#42) method (used by the unit tests), but I modified it to use [HostsFile::read_buffered](https://clarcharr.github.io/parse-hosts/parse_hosts/struct.HostsFile.html#method.read_buffered), which is doing the actual hosts parsing for a given string buffer. - [X] `./mach build -d` does not report any errors - [X] `./mach test-tidy` does not report any errors - [X] These changes fix #15756 . - [X] There are tests for these changes (tests/unit/net/resource_thread.rs and tests/unit/net/http_loader.rs) Source-Repo: https://github.com/servo/servo Source-Revision: 8f7c69e15f0b9beddad2ba67e3419f88aca0d579
