The attached part-1 patch moves related routines from hooks.c to label.c

I took a short look at this patch but am stuck getting the regression test
to run properly.
First, patch 2 misses the file sepgsql.sql.in and therefore the creation
function command for sepgsql_setcon is missing.
Thanks for your comments.
I added the definition of sepgsql_setcon function to sepgsql.sql.in file,
in addition to patch rebasing.
Very brief comments due to must leave keyboard soon:
I read the source code and played a bit with setcon and the debugger, no
strange things found.
Code comments / questions:
this comment below is a lie, because setcon is set by
sepgsql_xact_callback()
maybe client_label_committed is a better name for client_label_setcon?
static char *client_label_setcon = NULL; /* set by sepgsql_setcon() */
Is the double negation in the sentence below intended?
+ * Neither of them has no special state, the security label being
initialized
+ * at database-logon time shall be returned.
Is the assert client_label_peer != NULL in sepgsql_get_client_label
necessary?
sepgsql_set_client_label(), maybe add a comment to !new_label that it is
reset to the peer label.
new_label == NULL / pending_label->label == NULL means use the peer
label. Why not use the peer label instead?
set_label: if new_label == current label according to getcon, is it
necessary to add to the pending list?
sepgsql_subxact_callback(), could this be made easier to read by just
taking llast(client_label_pending), assert that plabel->subid == mySubId
and then list_delete on pointer of that listcell?
Some comments contain typos, I can spend some time on this, though I'm
not a native english speaker so it won't be perfect.
