All occurrences of the __value_type() and __distance_type() functions...

2001-07-17  Stephen M. Webb   <stephen@bregmasoft.com>r

All occurrences of the __value_type() and __distance_type()
functions, which were required to support the HP STL, have been
removed along with all the auxiliary forwarding functions that
were required to support their use.

The __iterator_category() function was pretty much left alone
because there was no benefit to removing it and its use made code
just a little more readable.

Incidences of distance() with nonstandard argument list were
replaced by calls to the standard function (only in the files
affected by the removal of the other HP functions).

The signature of the rotate() algorithm was changed to match the
standard.

Headers were reformatted under C++STYLE guidelines (indentation,
linebreaks, typename keyword).

* include/bits/stl_algo.h: replaced __value_type() and
__distance_type() with iterator_traits, eliminated auxiliary
support functions required to support said function usage.
Changed nonstandard distance() call to standard call.
