Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

Don't build tests with default "make" command.
Require explicit command to build tests because not everybody interested
in running unit tests.
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 preparation is required for dependency resolving and cleaning.

make config dependency resolving was always running serial,
parallelize it for better performance.
$ time make T=x86_64-native-linuxapp-gcc config
real 0m12.633s
$ time make -j8 T=x86_64-native-linuxapp-gcc config
real 0m1.826s
When config creation done under a single make target, using a for loop,
make has no control on the action, and it needs to run as implemented in
the rule. But if for loop converted into multiple targets, make can
detect independent targets and run them parallel based on -j parameter.

This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].

If .config file is changed and .depdirs was built before,
it must be updated.
It is now done silently (-s) in checkconfig rule.
Now .depdirs is not redone if .config is older.
It has been tested by enabling PMD_PCAP after a default build.
KVARGS dependency should appear in .depdirs.
There is also a typo fix for PHONY rule.
