This necessitates that non-pairable elements be briefly pushed on the stack, so that get_css_selector_for_element sees them, and then popped.
It would be possible to push them only when CONFIG_CSS is defined, as they are otherwise not needed (as evidenced by the fact that we've gone so long without bothering to push them). However, the performance hit should be small, the necessary #ifdef/#endif wrappers would be pretty ugly, and ideally, the CSS code will someday be in such a state that it can be considered an integral feature.
Instead, convert the element pointers inside the comparison functions.
The last argument of qsort() is supposed to be of type
int (*)(const void *, const void *). Previously, comp_links() was
defined to take struct link * instead of const void *, and the type
mismatch was silenced by casting the function pointer to void *.
This was in principle not portable because:
(1) The different pointer types may have different representations.
In a word-oriented machine, the const void * might include a byte
selector while the struct link * might not.
(2) Casting a function pointer to a data pointer can lose bits in some
memory models. Apparently this does not occur in POSIX-conforming
systems though, as dlsym() would fail if it did.
This commit also fixes hits_cmp() and compare_dir_entries(), which
had similar problems. However, I'm leaving alias_compare() in
src/intl/gettext/localealias.c unchanged for now, so as not to diverge
from the GNU version.
I also checked the bsearch() calls but they were all okay, apart from
one that used the alias_compare() mentioned above.
This is an attempt to make it easier to update without
requiring to update all translations.

start_document_refreshes() performs the NULL-pointer checks that
previously all callers to start_document_refresh() must perform
and then calls start_document_refresh().
