attempted fix in [42343].

The new header boost/iostreams/detail/config/rtl.hpp attempts to set the preprocessor symbols BOOST_IOSTREAMS_FD_XXX to correct values for XXX = open, close, read, write, seek, truncate, stat, and offset. The implementation of file_descriptor uses these constants where possible instead of using platform specific functions or types.

A new test, large_file_test.cpp, was introduced to test seeking with offsets of 1GB to 8GB. In order to enable this test, regression test runners will have to set one of the variables LARGE_FILE_TEMP or LARGE_FILE_KEEP to a pathname where the iostreams library can create an 8GB file.

Tested on Cygwin, which is like Darwin in that there are no foo64 functions, but off_t is 64-bit, and on Fedora 8 with _LARGEFILE64_SOURCE defined and _FILE_OFFSET_BITS undefined.

I am going to call this fixed.
