asterisk-16.x: add patch for AST-2021-001

180-AST-2019-007-16.diff refreshed.

Upstream patch for AST-2021-001 added. This patch is mainly for
res_pjsip_diversion, but the part that is patched there was added later
("res_pjsip_diversion: implement support for History-Info"), so asterisk
16.3.0 is not affected. Hence the res_pjsip_diversion part was removed
from the patch. The patch resolves similar overflow situations in
res_pjsip_path and res_pjsip_outbound_registration, so these were kept.

+Subject: [PATCH] res_pjsip_diversion: Fix adding more than one histinfo to
+ Supported
+
+New responses sent within a PJSIP sessions are based on those that were
+sent before. Therefore, adding/modifying a header once causes it to be
+sent on all responses that follow.
+
+Sending 181 Call Is Being Forwarded many times first adds "histinfo"
+duplicated more and more, and eventually overflows past the array
+boundary.
+
+This commit adds a check preventing adding "histinfo" more than once,
+and skipping it if there is no more space in the header.
+
+Similar overflow situations can also occur in res_pjsip_path and
+res_pjsip_outbound_registration so those were also modified to
+check the bounds and suppress duplicate Supported values.
