Daniel Roethlisberger 1c9aa249a9 Fix Travis build by disabling tests using IPv6
TravisCI has removed IPv6 support in 2016.  To cope with this regression
in the testing infrastructure, disable all tests on Travis that depend
on the system being able to handle ::1 as an IP address.  Normal unit
testing still uses the full test suite.

Daniel Roethlisberger ba2f451f5e Fix bev write handler for other->closed case
When other->closed is set, the bufferevent write handler accesses
other->bev even though it is invalid.  Fix this access, and as added
layer of defense against future bugs, set ->bev to NULL whenever
invalidating it, except where the connection is torn down completely.

Daniel Roethlisberger 17d753fc2d Fix NULL pointer dereference in bev write handler
Only manipulate other->bev if it is not NULL to avoid a NULL pointer

direction is fully established, for example during connection shutdown.

Daniel Roethlisberger 2bcfaf4b44 Re-enable EV_READ if disabled and outbuf empty
The event buffer write handler failes to re-enable the corresponding
read event of the opposite connection if the buffer is not only down to
less than half the limit, but completely emptied.  In that case, the
read event would never be re-enabled and the connection would stall and
time out.

Daniel Roethlisberger 02ab680b34 Add log to PCAP conversion script
Add contributed python script for parsing the output of sslsplit -L
from a log file or named pipe and converting the log entries to an
emulated PCAP format.  Information not contained in the log, such as
sequence numbers, IP IDs etc is emulated and does not correspond to the
original packets on the network.

Daniel Roethlisberger b95f46b8bd Add XNU headers for OS X 10.10.3, 10.10.4 and 10.10.5
Add pf ioctl API headers for XNU releases 2782.20.48 (10.10.3),
2782.30.5 (10.10.4) and 2782.40.9 (10.10.5).

Daniel Roethlisberger 0e2b748bba Only init DNS when DNS is required by proxy specs
Only initialize evdns if DNS lookups are actually required by the loaded
proxy specifications.  This allows sslsplit to work in non-DNS modes in
situations where the local DNS resolver does not work, such as for local
use on a system without network connectivity.  Currently, only SNI based
proxy specs require DNS.  On systems without network connectivity, DNS
subsystem init may fail due to /etc/resolv.conf being (temporarily)
unavailable.

Daniel Roethlisberger 79d570fe2e Use direct access workaround with LibreSSL
LibreSSL defines OPENSSL_VERSION_NUMBER == 0x20000000L and therefore
needs special treatment when detecting OpenSSL API features based on
OPENSSL_VERSION_NUMBER.  LibreSSL currently does not seem to implement
SSL_CTX_get0_chain_certs().  Once it does, there will be a need for a
specific version check on LIBRESSL_VERSION_NUMBER.

Daniel Roethlisberger 57a2ab8588 Rewrite protocol version macros and refactoring
Introduce HAVE_SSLV2, HAVE_SSLV3, HAVE_TLSV10, HAVE_TLSV11 and
HAVE_TLSV12 to indicate that support for the respective protocol is
available in OpenSSL.  This was necessary due to the increased
complexity of testing version support following the phasing out of SSLv2
and SSLv3 from OpenSSL implementations.  This fixes the build with
OpenSSL versions which have SSLv3 support removed.

While here, de-duplicate code for setting SSL_CTX options and do not set
SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION anymore; it has no benefit
in the context of splitting SSL/TLS for analysis.

Daniel Roethlisberger 74f62c3e5e Refactor and unify ClientHello parsers
Refactor and unify ssl_tls_clienthello_identify() and the earlier
ssl_tls_clienthello_parse_sni() into a single
ssl_tls_clienthello_parse() function that handles parsing ClientHello
messages for different purposes.  As a result, rename the debug knob
DEBUG_SNI_PARSER into DEBUG_CLIENTHELLO_PARSER.

Daniel Roethlisberger 64cc8ffcde Fix lib search w/o pkg-config w/multiple instances
Fix automatic search for dependencies when multiple instances of the
same library are installed in different prefixes that we search, by
using the first one found.  Automatic search is only used when
pkg-config was not found.  This fixes compiler errors caused by spurious
path names within compiler or linker flags, such as

    ld: can't map file, errno=22 file '/usr/lib' for architecture x86_64
    clang: error: linker command failed with exit code 1 (use -v to see
    invocation)

While here, also make XNU header version fallback more robust and add
(diabled) version mappings for 10.10.2 and 10.10.3 which are not
published by Apple yet.
