This happens often enough in contributors' workflows, when a work-in-progress branch is rebased changing e.g. only commit messages or the order or number of commits while leaving the resulting code intact, and is then pushed to a Travis CI-enabled GitHub fork. This is wasting Travis CI's resources and is sometimes scary-annoying when the new tip commit with a tree identical to the previous, successfully tested one is suddenly reported in red, because one of the OSX build jobs happened to exceed the time limit yet again. So extend our Travis CI build scripts to skip building commits whose trees have previously been successfully built and tested. Use the Travis CI cache feature to keep a record of the object names of trees that tested successfully, in a plain and simple flat text file, one line per tree object name. Append the current tree's object name at the end of every successful build job to this file, along with a bit of additional info about the build job (commit object name, Travis CI job number and id). Limit the size of this file to 1000 records, to prevent it from growing too large for git/git's forever living integration branches. Check, using a simple grep invocation, in each build job whether the current commit's tree is already in there, and skip the build if it is. Include a message in the skipped build job's trace log, containing the URL to the build job successfully testing that tree for the first time and instructions on how to force a re-build. Catch the case when a build job, which successfully built and tested a particular tree for the first time, is restarted and omit the URL of the previous build job's trace log, as in this case it's the same build job and the trace log has just been overwritten. Note: this won't kick in if two identical trees are on two different branches, because Travis CI caches are not shared between build jobs of different branches.

travis-ci: record and skip successfully built trees

Travis CI dutifully builds and tests each new branch tip, even if its
tree has previously been successfully built and tested.  This happens
often enough in contributors' workflows, when a work-in-progress
branch is rebased changing e.g. only commit messages or the order or
number of commits while leaving the resulting code intact, and is then
pushed to a Travis CI-enabled GitHub fork.

This is wasting Travis CI's resources and is sometimes scary-annoying
when the new tip commit with a tree identical to the previous,
successfully tested one is suddenly reported in red, because one of
the OSX build jobs happened to exceed the time limit yet again.

So extend our Travis CI build scripts to skip building commits whose
trees have previously been successfully built and tested.  Use the
Travis CI cache feature to keep a record of the object names of trees
that tested successfully, in a plain and simple flat text file, one
line per tree object name.  Append the current tree's object name at
the end of every successful build job to this file, along with a bit
of additional info about the build job (commit object name, Travis CI
job number and id).  Limit the size of this file to 1000 records, to
prevent it from growing too large for git/git's forever living
integration branches.  Check, using a simple grep invocation, in each
build job whether the current commit's tree is already in there, and
skip the build if it is.  Include a message in the skipped build job's
trace log, containing the URL to the build job successfully testing
that tree for the first time and instructions on how to force a
re-build.  Catch the case when a build job, which successfully built
and tested a particular tree for the first time, is restarted and omit
the URL of the previous build job's trace log, as in this case it's
the same build job and the trace log has just been overwritten.

Note: this won't kick in if two identical trees are on two different
branches, because Travis CI caches are not shared between build jobs
of different branches.

travis-ci: move Travis CI code into dedicated scripts

Most of the Travis CI commands are in the '.travis.yml'. The yml format
does not support functions and therefore code duplication is necessary
to run commands across all builds.

To fix this, add a library for common CI functions. Move all Travis CI
code into dedicated scripts and make them call the library first.
