Fix some doxygen warnings
libYARP_manager: set INCLUDE_DIRS property
Update Doxyfile to doxygen 1.8.7
Replace deprecated OUTPUT_PATH variables with OUTPUT_DIRECTORY equivalents
Use GNUInstallDirs variables

Also use DATADIR instead of DATAROOTDIR
Fix paths for build tree .ini files
PolyDriver::getImplementation returns dd->getImplementation

This change is due to propagate the getImplementation through nested
PolyDrivers untill it end in the real device driver.
The reason is that the view done on plugin devices were failing.
fix output of yarpdev --list for plugins

The default wrapper was not shown for plugins. This fix the issue
yarp plugin fix: The default wrapper is now instantiated using yarpdev command
from terminal.

A new variable is added in yarpPluginSetting to store the wrapper name and it
is used when calling the factory.
[ros] remove stray Makefile
[ros] propagate type name for yarp read+write
[ros] integration test for type name propagation
[ros] add experimental twiddle syntax to specify data type.

These two are now equivalent:
  yarp read /topic@/node --type package/typename
  yarp read /topic@/node~package/typename
This is for use with programs where changing the original code is
awkward.
allow hard-coded port /foo to be changed via YARP_RENAME_foo

Adds support for a port renaming method of last resort.
Suppose a program has a port called /foo/bar and there is no
way provided to change the name of that port other than
source code modification.  YARP already supports YARP_PORT_PREFIX
which allows us to add a prefix to all ports.  Now,
a port name can be changed entirely using YARP_RENAME_foo_bar.
For example:
  YARP_RENAME_read=/logger yarp read /read
will open a port named "/logger" for shells where this syntax
is permitted.  Renames (if present) are applied before prefixes
(if present).
