Use "\plugin::ext" instead of "ext"
  - allows for better warning messages
  - Ignored if plugin is not loaded / ext is not registered
  - raise an error if ext comes from a different plugin

This attribute is used by some STM32 compilers to allow function definitions
to be overridden by other function definitions.

Mergecil does not (easily) allow removing a previous existing definition to
override with a new one (undoing the former), but we can detect it and ask the
user to change the order of sources in the command line. In practice, this is
sufficient for some case studies.

This syntax is authorized by GCC/Clang and used in some libraries, such as
glib.

For now, we simply discard these attributes with a warning, since the examples
found so far are currently useless for Frama-C (e.g. 'deprecated').

- 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)
