[boost] [Config] proposal of new macro, BOOST_DECL

In order to export class from dynamic library
one needs to add something as:

    __declspec(dllexport)

wrapped in a macro. (Win32 example.)

Right now libraries define their own macros, e.g
Iostreams has BOOST_IO_DECL and Regex
uses BOOST_REGEX_DECL.
There could be more.

I suggest common macro, BOOST_DECL
to be used Boost-wide.

Its value may be by default empty or deduced
from BOOST_ALL_DYN_LINK
as it is done in Regex.
