CMake support for elf2cfetbl usage

[skliper]

The current CMake support structure does not include support
for the old style CFE Tables -- that is, where the table is
embodied in a source file within the application, which is
compiled with the application headers (as well as headers
from CFE, OSAL, and so on), and which is then converted from
the ELF Object File format into a TBL file.

Asking each project that wants to convert to CMake to independently
work out how to get the files compiled then converted is asking for
a significant duplication of effort -- as this turns out to be
something more than a couple easy lines of Make scripting. It is more
reasonable for us to work it out once, and provide a solution that
projects can use (or adapt) as desired.

I have set up a preliminary edit on Babelfish
in the "trac-48-cmake-elf2cfetbl-usage" branch,
currently in commit [changeset:143294b].

I have pushed commit [changeset:42d808f] with my proposed solution to this

This integrates "elf2cfetbl" into the CMake rules for an app.

• A new CMake function called {{{add_cfe_tables()}}} to define table files associated with an app. This can be included in the app-specific CMakeLists.txt file that is distributed with the application code.
• The function will first search in "tables" subdirectories of the the mission definitions and at the top level for an identically-named file, and use that as an override if one exists.
• If those do not exist, then the (default) table source included with the app is used.
• The table source file is compiled using the target compiler to produce an intermediate "o" file, using the same set of CFLAGS and include paths as the rest of the code for the app.
• "elf2cfetbl" is called to convert the "o" file into a tbl file.
• The tbl file is copied to the target tree during install

... somehow was not closed after the 07-28 integration was complete.
