[xslt] implementation of libexslt: dynamic:evaluate()

["Vakoc, Mark" <Mark_Vakoc jdedwards com>]

Attached is a patch for existing files and new file dynamic.c that sets up
the framework for http://exslt.org/dynamic and implements the [object
dyn:evaluate(string)] extension function.  It also modifies the Igor's win32
makefile (Makefile.msvc) and the unix Makefile.am to add the dynamic.c
module (Igor, it also adds a command to copy the generated .PDBs to the
bindir)

 <<dyn.diff>>  <<dynamic.c>> 

Also, the date.diff path simply adds #include <memory.h> to
libxslt/libexslt/date.c (which I needed to add because memset() was
undefined prior)
 <<date.diff>>
