Changes added in 4d1fd3775d break
automated updates by moving to a custom version scheme.
This switches back to upstream versioning, while maintaining version
schema convention of `builtins.parseDrvName`.
See issue #43717
xboxdrv doesn’t use scons for installing, but instead using a
makefile! Everything else is in scons so we have to keep that. I’ve
added a dontUseSconsInstall flag to the scons setup-hook to skip the
automatic overwrite of default “make install” call.
The scons build system is python-based and has a binary named scons. Unlike CMake, it cannot generate makefiles so we end up having to override the build, install, and check phases. I have added the setupHook to the scons package so that integration requires no unique steps - just putting scons in nativeBuildInputs should be enough. sconsFlags controls the flags specifically passed to scons while buildFlags, installFlags, and checkFlags should still be usable. Some packages use different names for the prefix flag. In those cases you will have to set "prefixKey" to something like "PREFIX=" as there are multiple names for the "prefix" used in scons.
The waf build system is python-based and hosted locally in each package in the executable file named "waf". Unlike CMake, it cannot generate makefiles so we end up having to override the configure, build, and install phases. I've tried to keep these as close to what's in setup.sh as possible. If there is no waf file in the root directory, then we just copy the one hosted in Nixpkgs. Otherwise the only thing you have to add to a package using Waf is "wafHook" into nativeBuildInputs. wafFlags controls the flags specifically passed to waf while configureFlags, buildFlags, and installFlags are still used as in the generic builder.
Bazel supports per-workspace bootstrap scripts at $WORKSPACE_ROOT/
tools/bazel. This adds support for this behavior, which is needed
by many Bazel projects (OSS and private).
For Git to work properly, I used fetchgit with leaveDotGit. This seems
to be causing hash to change on different systems in different times.
I've replaced generation of last_commit_position.h in tools/gen.py with
just plain nix template. "gn --version" will loose a bit (just commit
hash, without commit height in front of it), but I hope noone relies on
it.
This also updates the bootstrap tool builder to LLVM 5, but not the ones
we actually use for bootstrap. I'll make that change in a subsequent commit
so as to provide traceable provenance of the bootstrap tools.

`pants' works with requests==2.19 to build successfully and `nixpkgs' currently uses `requests==2.19.1`.
Patching the version constraint in `setup.py' accordingly fixes the problem.
Addresses #45960
- our version is from 2015
- it doesn't build
- upstream project is dead, last release 2012, last commit Oct 2016.
- used by only 1 nixpkgs package: `boo`, marked broken since 2016.
