improve structure of sources and formatted printer
* Create an `src/3rdparty` folder for third-party code (to add the
  Grisu2B alfogithm soon).
* Split the formatted printer into gint's kprint (src/kprint), its
  extension and interface (include/gint/kprint.h), and its use in the
  standard stdio functions (src/std/print.c).
* Slightly improve the interface of kformat_geometry() to avoid relying
  on knowing format specifiers.
* Add a function to register more formatters, to allow floating-point
  formatters without requiring them.

printf: fix %% doubling down as a format specifier
When parsing a %% format, the second % character was mistakenly not
skipped over after emitting a '%' output; this resulted in it being
treated as a format specifier. For instance,

  printf("%%d", 12);

would print "%12".

lephe 1685813078 libc: fix a pointer overflow in kprint
When the size of the input buffer is not specified, the default was
INT_MAX; however this will cause the pointer value to overflow in many
situations, causing kprint_flush() to flush prematurely and write NUL
bytes at inappropriate places.

This commit changes the default size to 65535. Morale: never use
sprintf() or vsprintf()...

lephe 2d7a6f154e libc: implement a compliant formatted printer
This is based on a port of kprint, which supports standard formats and
options, except for:

* Large parameters (ll)
* Floating-point types (%e, %E, %f, %F, %g, %G, %a, %A)
