copied strings from environment variables and argv[0] into
fixed-length buffers without checking their length.

Reported by Stan Bubrouski; advice on fix from John Viega.

   comes from two comp.lang.tcl postings of mine, with much rewriting
   and expansion of the material.
Note that 2.0 will be released in the autumn, not the summer.

deprecated after all.  But now they're only implemented once, instead
of N times.

implementations.  Details:
  * replace 'link_shared_object()', 'link_shared_lib()', and
    'link_executable()' with 'link()', which is (roughly)
    the union of the three methods it replaces
  * in all implementation classes (UnixCCompiler, MSVCCompiler, etc.),
    ditch the old 'link_*()' methods and replace them with 'link()'
  * in the abstract base class (CCompiler), add the old 'link_*()'
    methods as wrappers around the new 'link()' (they also print
    a warning of the deprecated interface)

Also increases consistency between MSVCCompiler and BCPPCompiler,
hopefully to make it easier to factor out the mythical WindowsCCompiler
class.  Details:
  * use 'self.linker' instead of 'self.link'
  * add ability to compile resource files to BCPPCompiler
  * added (redundant?) 'object_filename()' method to BCPPCompiler
  * only generate a .def file if 'export_symbols' defined

Minor rewrites, and added the CVS ID in a comment.

caused the drive letter to cause urlopen() to think it was an unrecognized
URL scheme.  This only passes system ids to urlopen() if the file does not
exist.  It works on Windows & Unix.

It should work everywhere else as well.

In the limits.h comment, noted that INT_MAX and LONG_MAX are guaranteed
to be defined.

Noted that Reliant UNIX now gets proper API support for extension modules.

Fred, check this!

Add definitions of INT_MAX and LONG_MAX to pyport.h.
Remove includes of limits.h and conditional definitions of INT_MAX
and LONG_MAX elsewhere.

This closes SourceForge patch #101659 and bug #115323.
