new function gstrdup

If the poppler sources are compiled with DBEUG_MEM, the gfree call gives an
error message if the memory is not allocated by gmalloc. But a very few
routines uses strdup to allocate and copy strings, and later use gfree to free
the allocated memory, which gives an error message if compiled with DEBUG_MEM.
One sample for this behaviour is Dict::Dict(Dict* dictA).
The attached patch introduces the new function gstrdup and use it everywhere
instead of strdup.
