(g_strdup_vprintf()): new function returning a newly allocated string containing the contents of *format and associated args (size is calculated with g_printf_string_upper_bound()). (g_strdup_printf): new function which wraps g_strdup_vprintf(). * configure.in: check for va_copy() or __va_copy() alternatively. check whether va_lists can be copyied by value. * glib.h: provide a definition for G_VA_COPY. * glib.h: * gmessages.c: (g_logv): (g_vsnprintf): pass va_lists by value, not by reference, since this causes problems on platforms that implement va_list as as arrays. internaly, use G_VA_COPY (new_arg, org_arg); va_end (new_arg); to produce a second va_list variable, if multiple passes are required. changed all callers. * glib.h: * gerror.h: renamed g_debug() to g_on_error_query(), cleaned up a bit. renamed g_stack_trace() to g_on_error_stack_trace() since both functions cluttered different namespaces. there is an appropriate comment in glib.h now that explains the unix and gdb specific dependencies of both functions. removed g_attach_process(). g_on_error_stack_trace() should probably be handled with caution, i've seem several different linux versions (2.0.x) become unstable after invokation of this function.
