Provide a new/similar macro RTE_LOG_LINE_PREFIX that accepts the prefix format and arguments as separate parameters allowing them to be expanded at the correct locations inside of RTE_FMT() allowing the rest of the non-prefix format string and arguments to be collapsed to the argument pack which can be directly forwarded with __VA_ARGS__ avoiding the need for conditional comma removal. I've done my best to manually check expansions (preprocessed) and compiled printf of the logs to validate correct output. v4: * remove unintended addition of prefix to bpf log helper. * use RTE_LOG_LINE_PREFIX in other places using RTE_FMT_HEAD and RTE_FMT_TAIL. * add a checkpatch check to prevent reintroduction of ##args. v3: * remove leading _ from RTE_LOG_COMMA the macro is not internal * add doxygen comment for existing RTE_LOG{,DP}_LINE function-like macros, based on RTE_LOG{,DP} comments. * add doxygen comment for new RTE_LOG{,DP}_LINE_PREFIX function-like macros, based on RTE_LOG{,DP} comments. * merge 2 vhost patches into a single patch (mistake in previous submission) v2: * revamp entire series to be ISO C99 compliant, stop using variadic argument pack extension.
