Basic syntax is presented below and allows users to define
nested structured types by using simpler or structure types as
members. Mig will use the C padding and alignment rules to produce
the same size as the corresponding C structures.
type timespec_t = struct {
uint32_t tv_sec;
uint32_t tv_nsec;
};
This allows us to build stubs that are more easily adaptable to other
architectures.

This is only done when data is inlined with a concrete size. It
ensures the C and Mig types have the same size in the target arch.
Tested by building the hurd package. No assertions were triggered.

This will allow to relieve constraints in callers, e.g. dir_lookup("") would
otherwise produce a warning with gcc-11 since char[1024] would mean that
dir_lookup would read all 1024 characters while it is not.
* utils.c (UserVarQualifier): Also use const_ qualifier when type is
string_t.
* tests/includes/types.h (const_string_t): New type.

This includes a set of valid and invalid definition files that MIG will
try to process. For valid definitions, GCC will compile the stubs to
check if valid C code was generated.
* configure.ac: Add new test Makefiles.
* Makefile.am: Add SUBDIRS.
* tests/Makeconf.am: Automake definitions shared by all test
subdirectories.
* tests/test_lib.sh: Library of functions shared by all test drivers.
* tests/good/run_good_test.sh: Script to run valid definition files.
* tests/good/Makefile.am: New file.
* tests/bad/Makefile.am: New file.
* tests/generate-only/Makefile.am: New file.
* tests/bad/run_bad_test.sh: Script to run invalid definition files.
* tests/generate-only/run_generate_only.sh: Script to run valid
definition files that should be generated only.
* tests/includes/*.h: Test header files that are included by test stubs.
* tests/good/*.defs: Valid definition files where
generated stubs can be compiled.
* tests/generate_only/*.defs: Valid definition files that can be
generated but no compilation should be attempted.
* tests/bad/*.defs: Definition files with problems that should be
detected by MIG.
