Instead of a raw string from the preprocessor, keep track of macro
definitions as a key/value list. This is a preliminary step towards
allowing the user to override some of these variables.

- fix f-string as reported by @maroneze
- --verbose is now reflected in `logging` level as well.

- --compile-flags="-c -I/path" works (i.e. there's no need to provide as many
  --compile-flags options as you have flags to pass to the compiler itself.
  Ditto for --cpp-arch-flags of course
- we start by checking that a minimal C file does not trigger a compiler error
  with the given option and we abort otherwise. This ensures that subsequent
  tests will not mistakenly take a configuration error for a genuine result.

Also fixes machdep-schema that was missing a type...

- sort imports
- avoid top-level import after code
- prefer 'sys.exit' instead of 'exit'
- avoid unnecessary '.keys()'
- '\w' in string is an anomalous backslash (W1401), "might be missing r prefix"

adds a test for avr_8 and avr_16. Turns out that embedded micro-controlers
have libc that are not exactly standard compliant

- fix various typos and inconsistencies
- add an option in make_machdep.py to validate an existing yaml file,
  and use it to validate manually written machdeps
- add macro with the name of the machdep (used in tests/syntax/assembly_gmp.c)
- add option to Frama-C to print the content of __fc_machdep.h on stdout
  and use that to compile our libc with gcc outside of Frama-C
  (as in tests/libc/runtime.c)

some POSIX macros will get standard values by default and can
be customized at runtime by user, though
