piegen: separates generated output from debug Introduce a new -o argument to piegen to specify generate file name. Send the debug stream to stdout and force it to /dev/null in the makefile if V=1 is not specify.

compel: simplify usage wrt ids Currently, some compel internals are exposed to user API (both C and CLI), making its usage more complicated than it can be. In particular, compel user have to specify a number of parameters (names for various data) on the command line, and when in C code assign a struc piegen_opt_t fields using the same names, without using those identifiers anywhere else in the code. It makes sense to hide this complexity from a user, which is what this commit does. First, remove the ability to specify individual names for data, instead introducing a prefix that is prepended to all the names. Second, generate a function %PREFIX%_setup_c_header() which does all the needed assignments. Third, convert users (criu/pie and compel test) to the new API. NOTE that this patch breaks ARM, as compel hgen is not used for ARM. This is to be fixed by a later patch in the series.
