Add to the contributors guide the requirements and guidelines for
getting patches acked and merged. It details at what point the review
comments and the ack's need to be received in order to have a given
patch merged into a release.

These guidelines are as agreed by the DPDK technical board at the
meeting held on 2017-02-15.

examples/quota_watermark: fix requirement for 2M pages

The sample app was forcing the shared memory block for high/low
watermarks to be placed in a memzone on 2M pages. This prevented it
from running on systems with just 1G pages, so remove the flag forcing
2M pages.

examples/quota_watermark: correct code indentation

The code indentation in the example app files used spaces rather than
tabs for indentation, and as such did not conform to DPDK conventions.
This left those modifying the code in a bind - to fix things on a line
by line basis so as to avoid checkpatch errors, or to keep things
consistent within the file, and accept checkpatch errors.

Since these files have not had too many changes since the original
import, there is little change history to lose by doing a complete
reformatting of the code, so just update all indentation to standard.
In the process, wrap long lines appropriately, avoiding splitting
error messages.

mk: add new test-basic rule

Since "make test" and "make test-build" does dependency resolving, they
check for all dependent components (lib and drivers) which takes a few
seconds.

This is a good feature during development, but if the target is only
running unit test, that step is unnecessary, it is possible to compile
once and run unit test multiple times, without checking any code update.

For this purpose, a new make rule "make test-basic" added. Which only
runs the unit test, expects that unit test already compiled.

Following changes done in make rules:
"make test-build"  <--- Added
"make test"        <--- Updated functionality (build + run basic tests)

Now "make test" builds all tests and runs unit test (test).

Thanks to dependency resolving, it is possible to call "make test"
directly after config, "make test" will compile dependent components
(lib and drivers, but not apps).

And a new "make test-build" make rule added which will build
tests but not run unit test. "make test-build" has same dependency
resolving features with "make test"

To include "test" folder into makesystem, existing ROOTDIRS- variable
is used instead of hardcoding folder name into makefiles, current usage
of ROOTDIRS* variables are:

ROOTDIRS-y <-- root level folders prepared and compiled by default
ROOTDIRS-  <-- root level folders prepared but not compiled by default

The overflow: hidden attribute is used to mask the generated content
outside of the table.

The class .wy-nav-content has a background which masks the highlighting.
Setting an opacity lower than 1, creates a new stack context and let

doc: announce API changes for vhost

I made a vhost ABI/API refactoring at v16.04, meant to avoid such issue
forever. Well, apparently, I lied.

People are looking for more vhost-user options now days, other than
vhost-user net only. For example, SPDK (Storage Performance Development
Kit) are looking for chance of vhost-user SCSI and vhost-user block.

Apparently, they also need a vhost-user backend, while DPDK already
has a (mature enough) backend, they don't want to implement it again
from scratch. They want to leverage the one DPDK provides.

However, the last refactoring hasn't done that right, at least it's
not friendly for extending vhost-user to add more devices support.
For example, different virtio devices has its own feature set, while
APIs like rte_vhost_feature_disable(feature_mask) have no option to
tell the device type. Thus, a more proper API should look like:

    rte_vhost_feature_disable(device_type, feature_mask);

Besides that, few public files and structures should be renamed, to
not let it bind to virtio-net. Specifically, they are:

- virtio_net_device_ops --> vhost_device_ops
- rte_virtio_net.h      --> rte_vhost.h
