* chore: add protoc-gen script to releng
* chore: break cross-container-tag into separate variable
* fix: call GNUMakefile "generate-sources" target instead
This also does a better job at mounting the root directory
in the docker container.
The releng scripts' tarballs had paths like `./usr/bin/influx` whereas
the build.py output had `./influxdb-1.3.5-1/usr/bin/influx`. Now the
releng scripts match the build.py output.
The *.1.gz files are included into the source tarball, and the .deb and
.rpm files will now install the man pages when the package is installed.
Fixes#8908.
Added several docker-based scripts that can be used to build the OSS binaries and Debian and CentOS packages in a clean, standardized environment. Supports Windows, OSX, and Linux on AMD64 as well as multiple chip architectures for linux including i386, arm5, arm6 and arm8. Will also package source code with all necessary dependencies, and run basic unit tests in the same environment.
