to AST-2017-005.
The RTP/RTCP stack will now validate RTCP packets before processing
them. Packets failing validation are discarded. RTP stream qualification
now requires the intended series of packets from the same address
without seeing packets from a different source address to accept a new
source address.

also install the basic-pbx sample configs
which are gcc-specific, or clang with -fblocks, which we don't have
working fully yet).
To avoid a C++ standard library conflict, switch to a stripped-down and
patched copy of pjsua/pjsip built as part of the Asterisk build.
Some slight patch gymnastics; Asterisk doesn't distribute pjsua itself
but rather normally downloads, untars and patches as part of the build,
which isn't compatible with the patches we need to apply in order to
fix it with libressl.
on short SCCP packets. This only affects SCCP users (chan_skinny).
13.15.1 also added some fixes to the bundled copy of PJSIP
(used by chan_pjsip, *not* used by chan_sip) -
AST-2017-002: Buffer Overrun in PJSIP transaction layer,
AST-2017-003: Crash in PJSIP multi-part body parser
- however that copy is not used by this package and will need to
be fixed separately.
- clang + ld.bfd: link fails in autoconf test, undefined symbols.
- clang + ld.lld: package builds, dlopen()ing the .so modules that use -fblocks
fails at runtime.
because with clang + ld.lld it does build but results in unusable packages,
explicitly mark BROKEN-aarch64 for now.
add various OPENSSL_VERSION_NUMBER patches now that asterisk supports
openssl 1.1:
- we don't have openssl 1.1's SSL_is_server yet, so use the old check
for ssl->server instead
- we do still need the hack to avoid initing multiple times which is
no longer needed in openssl 1.1

CDR: Protect from data overflow in ast_cdr_setuserfield.
ast_cdr_setuserfield wrote to a fixed length field using strcpy.
This could result in a buffer overrun when called from chan_sip or
func_cdr. This patch adds a maximum bytes written to the field by using
ast_copy_string instead.
both fail to provide %zu samples" debug message which is triggering very
frequently, so that it's possible to get debug level 5 messages without
flattening the box.
OPENSSL_VERSION_NUMBER < 0x10002000L to see if DTLSv1_method is available;
it's an error at runtime only as it's in a dlopen'd module, and doesn't
crash the process, just fails loading the module, so you don't notice
until you wonder why calls are all failing...)
this is a major update - upgrading users should review UPGRADE-12.txt and
UPGRADE.txt in /usr/local/share/doc/asterisk. some configurations will work
unchanged, but there have been big changes in other areas, notably AMI,
CDR and CEL.
