Since go1.8 GOPATH is not required to set prior, as
it defaults to "${HOME}/go" we only need to check if
go tool detected GOPATH correctly. If yes then we
proceed if not we fail.
This PR implements an object layer which
combines input erasure sets of XL layers
into a unified namespace.
This object layer extends the existing
erasure coded implementation, it is assumed
in this design that providing > 16 disks is
a static configuration as well i.e if you started
the setup with 32 disks with 4 sets 8 disks per
pack then you would need to provide 4 sets always.
Some design details and restrictions:
- Objects are distributed using consistent ordering
to a unique erasure coded layer.
- Each pack has its own dsync so locks are synchronized
properly at pack (erasure layer).
- Each pack still has a maximum of 16 disks
requirement, you can start with multiple
such sets statically.
- Static sets set of disks and cannot be
changed, there is no elastic expansion allowed.
- Static sets set of disks and cannot be
changed, there is no elastic removal allowed.
- ListObjects() across sets can be noticeably
slower since List happens on all servers,
and is merged at this sets layer.

It was decided that we will be deprecating ARM support
for minio builds. ARM users should simply compile from source.
Additionally 32bit version of Linux, Windows and FreeBSD (64bit)
are deprecated.
Wait for remote hosts to resolve instead of failing on first host
resolution error, when running in Kubernetes or Docker environment.
Note that
- Waiting is based on exponential back-off mechanism
- If run as a binary, server fails if remote host is not resolvable
This is needed because in orchestration platforms like Kubernetes, remote
hosts are started sequentially and all the hosts are not up initially,
though they are expected to come up in a short time frame
It is difficult to identify a cap on the waiting time due to
non-deterministic nature of infrastructure platforms, so the server waits
infinitely for the hosts to come up, while logging the error messages to
the console.

Swarm routes traffic only to containers that report healthy status,
while Minio in distributed mode needs to talk to other peers before
it can respond to healthcheck probe. As the Minio containers are not
able to talk to each other, distributed Minio is not getting started
on Docker Swarm.
With this PR, Minio Healthcheck report healthy status for initial
120s enough for distributed Minio to start. After that normal
Healthcheck resumes. Also changed the healthcheck method name
in accordance with Google shell styleguide.

Additionally remove support for arm6vl in release, since
go 1.8 the support for armv6 has been dropped and we do
not see high usage events from this platform.
Currently due to the occurrence of 6 arguments from
`gen-ldflags.go` leads to a bug where the binaries
genenerated have wrong names.
As shown below.

This PR fixes this issue by retaining the previous release
binary names.

Update the check_minimum_version function to use numeric comparison (not
string comparison) on components of version numbers. Fixes the following
output:
```
$ make
Checking deps:
ERROR
OSX version '10.11.6' not supported.
Minimum supported version: 10.8
make: *** [checks] Error 1
```
