release: ninja v1.7.1

[Nico Weber]

I've tagged a new release of Ninja, version v1.7.1

(I've also tagged v1.7.0, but don't use that.)

This is the first release after moving the homepage to https://ninja-build.org

and the repo to github.com/ninja-build.

== Release notes

* New feature: Implicit outputs (#989)

  Documented in the manual at https://ninja-build.org/manual.html#ref_outputs

* Output formatting changes

  + in non-interactive mode, print commands when finished, not when started --

    build output is now always preceded by the command that produced it (#999)

  + as a consequence, the default NINJA_STATUS is now "[%f/%t] " and %p

    is percentage of finished edges instead of percentage of started (#1142)

  + for failing commands, print "FAILED: output name" followed by the

    faiilng command on a new line, instead of "FAILED: command" (#1033)

* Several documentation updates

* Minor changes and bugfixes

  + "./" in paths is no longer an error but instead canonicalizes to nothing

    (#1076)

  + New debugging flag `-d keepdepfile` (#1098)

  + `-w dupbuild=err` now works in subninjas (#1095)

  + Don't loop forever in dry-run mode if the generator rule is dirty (#1069)

  + `msvc_deps_prefix` can now be set per-rule, not just globally (#1043)

  + allow non-ANSI characters in depfiles (#763)

  + `-k 0` now works better with pools (#1017, #1023, #1126)

* `-t browse` changes

  + new --port and --no-browser flags; default to 'all' target (#1112)

  + make tool work if main build file isn't called build.ninja (#1116)

* Windows-specific changes

  + don't crash with deps=msvc if the compiler prints very long include notes

    (#973)

* POSIX-specific changes

  + Clean up build on SIGHUP (#964)

  + subprocesses are now spawned via posix_spawn instead of fork/exec, which

    speeds up builds on some systems (e.g Mac OS X) (#1118)

  + child processes no longer detached from terminal, restoring 1.5.0 behavior

    (#1113)

  + experimentally expose deps=msvc on non-Windows too (#1125)

* Changes to building ninja itself

  + allow bootstrapping ninja itself in an out-of-source build dir (#979)

  + make ninja build on AIX (#1007)

  + ninja's source compiles with MSVC2015 (#1003, #1110, #1130)

  + ninja's source now also compiles with MSVC2008 (!) (#1101)

  + ninja's source builds with libc++ on Linux (#1134)

* Changes to scripts

  + zsh target completion is faster (#1046)

  + bash target completion is faster (#1047)

  + ninja_syntax: don't wrap long words in comments (#1042)

  + ninja_syntax: support implicit outputs
