Reindent all source code.

Reindent complete source code (*.c, *.h) with indent, the exact command
line being:
indent -kr -i4 -bap -nut -l76 *.c *.h

From now on, new code should use (more or less) K&R style,
only spaces and no tabs, 4 spaces indent width. Avoid long lines.

Fix function declaration pointer spacing.

Remove spaces that were added to many function declarations by indent,
like some_func(foo_t * bar).
Fix indenting of macros in ass.c
