nb: i should really add 'make test' in the git commit hooks!

And it is now done only by Lic2soc (L2lCheckLoops is not used anymore)

Also, during this change, I was bitten again by the « "__" versus "::" in ident
names » problem again.

The core of this problem is due to the fact that I use LicDump both for
(1) dealing with internal ident names
(2) generating lustre files

Because of (2), ident names may depend on the ec or the v4 option. hence, internal
names were sometimes translated with "__" instead of "::".

To (try to) fix that, I've added a boolean flag to all "to_string" functions that
states whether the function is used for internal purposes, or for generating lustre
files.

It was quite a boring change, that triggered other problems, that I've fixed
in this (too long) commit :
 - -esa should force -en, otherwise bad things happen (-esa is used for -ec anyway)
 - in -esa mode, #/nor inputs tuples of bool, not arrays
 - fix the list of predi op that returns a type different that its arg (SocPredef)

Also, use rdbg instead of lurettetop to run the test.

Reference Manual enhancements.

Also, do not set the seed when comparing compilers.

More precisely, issuing an "exit 2" is not enough for the
should_work proc in test/site.exp to state that the test fails.

That fix revealed a certain number of bad programs.
Some were not really wrong ; there were just not respecting the
naming convention used to automated the test (i.e., main node name =
file name).

It also releaved a real bug due to the fact that type
instanciatiation is not propagated during model instanciatiation,
where creates a loop between (Lic2soc.process_node and
Lic2soc.soc_of_node). Indeed it searches in the soc the table for an
abstract profile.

I know they fail, but I'll fix that latter.

Also disable tests that involves ecxexe with files that contain 'merge'.
indeed the -ec backend is not the priority.

To acheive that, I gave a diffretent name to each created executable
(vs a.out) to avoids races.

generation has been stopped in the middle of the process because of
an error in order to avoid to run test that will fail for sure.

Also remove the port number from the sum files

by taking advantage of the multi-proc -> x5 speedup with j 4 !

Note that i do not use -j 4 (qtest) for reference (reftest) to lower
timings distorsion due to the machine load.

For instance, do not launch tests that perform result comparison (via
lurette) on files that contains extern nodes (as they cannot be
executed) or package.  Package do not work because appending the
tested lustre file with the generated oracle as I do is wrong in
presence of package.

Moreover, my current test process is not able to test programs which
main node IOs are not all on the base clock. I have fixed this by
patching the examples.

# of expected passes 		1508 -> 1512
# of unexpected failures	130 -> 84

30 tests fail, but 169 pass!!!

# of expected passes 		1339 -> 1508
# of unexpected failures	100 -> 130

# of unexpected failures	101->109

but actually, some new test passes causes several other failing test
to be tried, so it is not really a regression.

Also add support to rdbg to perform nonreg test. I do not plug yet it
as it's twice slower. but most of it seems due patch_ecexe. Indeed,
lus2lic -interface compile the whole program just to print the node
interface.

nb: it has detected a couple of existing bugs.

That was quite confusing for rdbg -lurette --*-stdio !!!

  #fail: 83 -> 81

The test now runs in 150s (versus 417s)

[...] for some reasons, i cannot reproduce the 150s !!!

itself calls another node on a non-trivial clock (i.e., using a when)
was not producing correct code.

I've fixed this by performing the fix-point on nodes rather than on
equations. Indeed its more natural and efficient, and it avoid the
problem above. However, I did not really fix the problem, but just
turn around it. All tests seems to work fine though.

nb : #FAILS=81->80 (and -2 unresolved, but because I fixed the prog)

112 tests failed, and 127 passed !!

Plug back the enums expansion (-ee, --expand-enums) that translates enum types using extern consts and types.

Remove all test that now passes from the broken dir.

It was beacause the tables in LicVarName were cleaned and because the way
this module work sucks...

Also do not print type and const declarations with -ec.

nb : I've transformed all the regressions I've seen into todo entries
in todo.org.

nb 2 : I did not mv the newly broken tests into the broken dirs. I'll
do that for those I do not want to fix in the short term.
