eal: add missing C++ guards

[ upstream commit d7e9c02 ] Some public header files were missing 'extern "C"' C++ guards, and couldn't be used by C++ applications. Add the missing guards. Fixes: af75078 ("first public release") Fixes: 7f3aa08 ("eal: introduce bit operations API") Fixes: 166a743 ("compat: add infrastructure to support symbol versioning") Fixes: 8f40ee0 ("eal/x86: get hypervisor name") Fixes: 75583b0 ("eal: add keep alive monitoring") Fixes: 8870164 ("eal: move interrupt type out of igb_uio") Fixes: f04519d ("lib: add missing include dependencies") Fixes: f588806 ("trace: implement register API") Fixes: 428eb98 ("eal: add OS specific header file") Signed-off-by: Brian Dooley <brian.dooley@intel.com> Acked-by: Bruce Richardson <bruce.richardson@intel.com> Acked-by: Tyler Retzlaff <roretzla@linux.microsoft.com>
