James E. King, III 0ad20bdbfe THRIFT-4351: use travis build stages to optimize build,
avoiding duplicate rebuilds of the same image, and also
allow personal docker hub repositories for private fork
builds to be optimized. Move ubsan build to artful image
because it catches more stuff and fix what was found.

THRIFT-4345: solidify docker build strategy for maximum
coverage: trusty, xenial, artful as stock as they can be

THRIFT-4344: add top level language summary markdown and
update readme with a new image on the layered architecture

THRIFT-3847: remove VERSION macro from config.h which
was causing a conflict on artful builds.

THRIFT-4359: fix haxe map/set decode when key is binary,
as a missing break statement caused it to use an int
during decode

# SYNOPSIS
#
# AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
#
# DESCRIPTION
#
# Look for OpenSSL in a number of default spots, or in a user-selected
# spot (via --with-openssl). Sets
#
# OPENSSL_INCLUDES to the include directives required
# OPENSSL_LIBS to the -l directives required
# OPENSSL_LDFLAGS to the -L or -R flags required
#
# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
#
# This macro sets OPENSSL_INCLUDES such that source files should use the
# openssl/ directory in include directives:
#
# #include <openssl/hmac.h>
