Allow flags to be followed directly by their argument, separated by an '='
sign. This is consistent with what GNU getopt_long and many other
command line parsing libraries allow.
Fix for the following issue:
http://caml.inria.fr/mantis/view.php?id=5197
The no_arg function in this patch is a no-op. It will do something
useful in the followups.
The get_arg function simple checks the next position on the command
line exists and returns that argument or raises a Arg.Missing.
This patch should introduce no functional change, it is simply code
refactoring.
In particular, this should not change the treatment of Arg.current
(see: http://caml.inria.fr/mantis/view.php?id=5197#c11147)
Merge of branch 'hex-float'.
- Add support in byterun/floats.c for conversions between floats and strings in hex notation. We cannot rely on the C standard library here because Microsoft consistently fails at supporting hex notation as standardized in C99. Instead, the conversions are implemented from scratch.
- Add support in the lexer so that hex float literals are recognized in OCaml sources.
- Add support in formats. The ISO C99 format letters for hex floats are %a and %A, but %a is already taken. I chose %h and %H, which are rejected today as bad formats (hence no backward incompatibility) and don't mean anything in C either (h is a modifier, not a format letter).
- Add support in printf. All the trimmings are there in the implementation of %h and %H, including sign modifier and fixed precision.
- Benoit Vaugon contributed support in scanf.

- use inline-records to avoid using Obj.magic while keeping
indirections to the minumum
- change the representation from a cyclic list to a simply-linked
list. The drawback is one more word per queue, but it makes the
implementation clearer

This attributes is applied on predefined exception constructors
which take an purely informational (with no stability guarantee)
message.

Turn Stream.data into a GADT to ensure that streams built with the
Sbuffio constructor are char streams.

Stream used to modify blocks allocated as immutable. This Get rid of
most Obj module invocations in this module.

breaking, consistent usage of splitting and split; simpler explanation for
break hints and new documentation for pretty-printing boxes.
Tabulation boxes get deprecated: this mechanism does not interact nicely with
the rest of the pretty-printing engine and should be completely revisited...

flush_str_formatter rewritten using flush_buffer_formatter.
Consistent naming of pretty-printer formatter as ppf not strange x or o
parameters.
Function ksprintf purposedly defines a new continuation embedding the old
one.
Function asprintf rewritten in a more natural way; spurious pp_flush_queue
deleted in the conitnuation, since it is already done via following
flush_buffer_formatter call.
Indent.
