LibreSSL does not yet work well with Windows meterpreter for 2 reasons:
1. because its built with mingw/gcc, it does not have SAFESEH, requiring that
protection to be disabled for the whole stack. It could, it just needs a
way to be built with MSVS instead.
2. OpenSSL 1.0.1 and Libressl both make metsrv about 50% larger.
When transports are more abstracted and LibreSSL can build with MSVS, we will
revisit this.
* r7_debug and r7_release configurations added.
* Make now detects if the appropriate libraries are on disk and will build
whatever it can. If PSSDK is present in the appropriate location then it
will attempt to build ext_server_sniffer.
* ext_server_sniffer is now buildable with VS 2012 with all the settings
correct.
* ext_server_sniffer was failing to load once built. The cause of this was
that the hMetSrv handle wasn't being set to a valid value prior to the
command_register calls happening, it was being set too late. I'm not
sure why this results in a crash, but moving this one call to a location
prior to the command_register calls does resolve that problem.
* Perform the upgrade of the projects using the VS wizard.
* Exclude the ext_server_pivot project for now as it doesn't exist on
disk.
Note: this changeset will not compile.
