usleep is deprecated and disabled in glibc 2.12 unless requested. Use
nanosleep instead if available.
This fixes the following compiler warning:
./src/zrtp_iface_scheduler.c: In function 'zrtp_sleep':
./src/zrtp_iface_scheduler.c:96:2: warning: implicit declaration of
function 'usleep' [-Wimplicit-function-declaration]
usleep(msec*1000);
^
These two files should only be built when OpenSSL is not enabled. See
the configure script of the original sources and Makefile from upstream.

Fixes a -Wimplicit-function-declaration warning.
This removes our in-tree version of portaudio-19 and migrates
mod_portaudio and mod_portaudio_stream to use the system version of
the library. Our detection of the system library relies on
pkg-config.
This reverts commit b29a41bb1bf104113596c2f28a6cf255a1119c64.
This commit is no longer needed now that proper infrastructure has been
added to allow signaling modules to generate and detect DTMF
The feature macros should only be used for I/O module features
and not for signaling module features
In `srtp_unprotect_rtcp()` we are not validating that the packet
length is as long as the minimum required. This would cause
`enc_octet_len` to underflow, which would cause us to try to decrypt
data past the end of the packet in memory -- a buffer over-read and
buffer overflow.
In `srtp_protect_rtcp()`, we were similarly not validating the packet
length. Here we were also polluting the address of the SRTCP
encrypted flag and index (the `trailer`), causing us to write one word
to a bogus memory address before getting to the encryption where we
would also overflow.
In this commit we add checks to appropriately validate the RTCP/SRTCP
packet lengths.
`srtp_unprotect_rtcp_aead()` (but not protect) did correctly validate
the packet length; this check would now be redundant as the check in
`srtcp_unprotect_rtcp()` will also run first, so it has been removed.
