Rather than assuming the static version of libcrypto exists for pulling in the compatibility functions, link the compat objects directly. This modifies the object file generation script a bit to handle the empty-case properly as well.
- Output object files list variable for libcrypto and libssl to .mk file.
- Include object files list variable .mk from tls/Makefile
- Link .lo files directly instead of static library for libtls.
An issue that Reyk Floeter noted while building a Debian package for
LibreSSL is that installing libtls along with OpenSSL causes linker
issues since it will often pick up the wrong libcrypto/libssl. This
change makes libtls statically link the object files it needs rather
than relying on the shared libraries, effectively making libtls
self-contained and able to be packaged independently.
This should make it possible for other projects that also use libtls to
be able to package support without requiring the target OS to ship
libcrypto / libssl from LibreSSL.

CMAKE_HOST_ describes the host system not the target. For cross compilation to work the actual target system should be used for making decisions in CMake.
Internally LIBRESSL_SKIP_INSTALL, if not set becomes ENABLE_LIBRESSL_INSTALL so this by default is enabled. defining LIBRESSL_SKIP_INSTALL before hand will disable all install() rules.
This is useful if another project includes and links to this statically.
I chose to add a prefix to avoid potential name collision because the options are cached globally.
If the installation is skipped, maybe it should also disable building apps? I didn't do that.
- add cmake build options as configure provides
* -DENABLE_ASM (default ON)
* -DENABLE_EXTRATESTS (default OFF)
* -DENABLE_NC (default OFF)
* -DOPENSSLDIR (default ${CMAKE_INSTALL_PREFIX}/etc/ssl)
- add biotest and pidwraptest if ENABLE_EXTRATESTS is ON
- add compiler flag `-fno-common` if CMAKE_SYSTEM_NAME is Darwin
to prevent link error Undefined symbols "_OPENSSL_ia32cap_P"
- modify structure of CMakeLists.txt under apps/
* move apps/CMakeLists.txt to apps/openssl/ since this is for openssl build
* create new apps/nc/CMakeLists.txt for nc build
* modify apps/CMakeLists.txt just add_subdirectory()
- add checking and compile of arc4random_uniform()
- add installing man files, openssl.1 and nc.1
VS2013 has trouble with relative include paths for apps/openssl, so move
certhash_win/apps_win.c back to apps/openssl.
