Things not done because probably disruptive:
* kmod filesystem string
* sysctl/debugfs/trace
* metrics names
* xmon instance names
Some of these might be renamed too, but starting with a relatively
safe set.
Initial version really by Pawel, but many changes in between.
Big outstanding issues:
* span cache reclamation (unbounded memory otherwise...)
* bad block service detection and workarounds
* corrupted blocks detection and workaround

The go deps are vendored as source files, the C++ deps are vendored
as artifactory tarballs rather than internet tarballs.
Good practice, but the immediate motivation was to allow Saulius
to build stuff in Iceland.
Also, produce fully static binaries. This means that `gethostname`
does not work (doesn't work with static glibc unless you build it
with `--enable-static-nss`, which no distro builds glibc with).
Most operations apart from spans-related ones work. Using this as
a checkpoint -- the Python code is currently not really working,
I'm working to migrate to pretty much a full C++/go world.
