Josef Söntgen c25c4e3411 ram_blk: transition to the new base API 
In addition to modernizing the component now also supports using
empty RAM dataspace as backing store.

For example to use an ISO file the component has to be configured
as follows:

! <config file="image.iso" block_size="2048"/>

To use a empty RAM dataspace that is 256MiB large and has a block
size of 4KiB the configuration looks like this:

! <config size="256M" block_size="4096"/>

Either 'size' or 'file' has to specified. If both are declared the
'file' attribute is soley evaluated.

Issue #1987.

Fixes #2031.

RAM block device is an implementation of the block-session interface
running as a client of a RAM session. It either populates the RAM dataspace
by using a ROM dataspace, similiar to loop devices. For example to use
an ISO file the component has to be configured as follows:

! <config file="image.iso" block_size="2048"/>

To use a empty RAM dataspace that is 256MiB large and has a block size
of 4KiB the configuration looks like this:

! <config size="256M" block_size="4096"/>

Either 'size' or 'file' has to specified. If both are declared the 'file'
attribute is soley evaluated.
