[libposix-development] printf parser

[Henrique A. <hd...@gm...>]

 I'm approaching a complete printf implementation, and I've just
updated a printf parser to the repository, which is already in an
advanced state. It's able to parse non trivial strings, like "e %-2ld
f %0#'133.45Lg g %+.hhX i\n". The actual output functions
(output_unsigned, output_double, etc.) are still missing, so it
doesn't print anything yet, but I'll start writing those soon. Also
missing are dealing with "numbered arguments" (things like "%2$d %1$s
%3$g", they allow out of order argument passing), which are harder and
require a working malloc implementation.

 Please run the tests "printf_parser" and "printf_scanner" and check
that they don't crash or give weird results. printf_scanner should
return zero and printf_parser should have the following result at the
moment:

abcd
e  f  g  i

 I expect to finish this until the middle of the week, so that we have
a nearly complete printf.
