REORG: tproxy: prepare the transparent proxy defines for accepting other OSes
This patch does not change the logic of the code, it only changes the
way OS-specific defines are tested.
At the moment the transparent proxy code heavily depends on Linux-specific
defines. This first patch introduces a new define "CONFIG_HAP_TRANSPARENT"
which is set every time the defines used by transparent proxy are present.
This also means that with an up-to-date libc, it should not be necessary
anymore to force CONFIG_HAP_LINUX_TPROXY during the build, as the flags
will automatically be detected.
The CTTPROXY flags still remain separate because this older API doesn't
work the same way.
A new line has been added in the version output for haproxy -vv to indicate
what transparent proxy support is available.
