Rather finalize what's underway and finish the Big Cleanup:
- Check what can be cut from the xbt
- "pull" code diffusion in graspe
- - document the gras' timing macro
- add a real implementation (even if simplistic) to gras_os_myname
----
* Rename gras_get_my_fqdn to gras_os_myname and implement it in the simulator
RL would imply a DNS resolver, which is *hard* to do in a portable way
(and therefore delayed).
+ * Implement a real timer mecanism and use it in timing macros. This allows
+ to avoid rounding errors and get a 0.000005 sec precision in timing
+ macros. While I was at it, various cleanups:
+ - allow to declare more than one timed section per file (fix a stupid bug)
+ - move some private declaration to the right place
+ - the chrono module now cleanups its mess on gras exit
+ - merge conditional execution and timing macros into emulation module
+ - document the module
