Indicate both successful decodes and errors.

Previously the type ssrc_specific was used, this effectively
meant that only the first SSRC in the input would ever be able
to be decoded.
This would be ok in some cases but the input is never validated
so when processing pcap files the first packet would bet treated
as an RTP packet regardless of its actual content.
By changing to ssrc_any_inbound, rtp_decoder becomes more flexible
and supports SSRC multiplexing.

Add -m flag to set the mode to either rtp (default), rtcp
or rtcp-mux (rfc5761).

The key size was incorrectly used to determine the
policy function to use. The correct variable to check
against was the tag size.

rtp_decoder fix checking against tag size

Extend rtp_ecoder to support RTCP and multiplexed SSRC's

This can potentially replace the visual studio build files.

These can now be generated with e.g.:

  cmake . -G "Visual Studio 15"

Or for 64 bit:

  cmake . -G "Visual Studio 15 2017 Win64"

Also updated readme to reflect this.

So it also compiles in Visual Studio 2012 which uses C89.

If this code is to be in the libSRTP repo and it
is libSRTP specific then it is reasonable that it
follows the libSRTP format guide.

required to get Makefile on fuzzer directory

The intention is not to run the fuzzer but to
ensure build breakage is detected.

Requires a newish version of clang so bump distro
to xenial

Reusing a EVP_CIPHER_CTX between EVP_*Init_ex() calls is not allowed
unless one calls EVP_CIPHER_CTX_init() first.

EVP_EncryptInit_ex() expects the cipher context to be initialized, which
isn't done by EVP_CIPHER_CTX_new() in OpenSSL-1.1.x.

Implement fuzzers

Make it easy to use lib in VS2012

With openssl 1.1 this will map to the same
EVP_CIPHER_CTX_reset function.
With older version it will ensure memory is
released when the ctx is reused.

Remove hard coded config and allow cmake to be used
on windows, linux & osx

Adds support for debugging and openssl.
Add high level test apps.

This enables multiple builds from same source tree.

cmake support

Not supported on older msvc version and
was previously hard coded.

Since rand_s is only supported on windows
and this functions is only for tests.

This preserves the exisiting behaviour if
config.h_win32vc7 was used.

This should round off cisco#393

This prevents the NULL being passed srtp_err_report
when the format string did not expect an argument.
This should have no function change but enabled
better checking of format arguments.

travis osx builds that use brew seam to need a
newer version of xcode in order to have a ruby
version that works. This really should have been
automatic on the travis side.
Nss is now pre installed.

Allow the pcap file to be read from a physical file, but maintain
default stdin behaviour.

Allow the byte offset of the RTP packet to be specified such that if a
non-tcp transport is used (e.g. UDP) the RTP packet can still be read
correctly.

Add extra command line options for more flexibility

This prevents hardcoded paths from breaking

Bump version

Modify cmake to install crypto_types.h instead of cipher_types.h

This avoids overriding LD_LIBRARY_PATH that may be set by the user who
invokes the building/testing process when not necessary.

Don't set LD_LIBRARY_PATH if CRYPTO_LIBDIR is not set
