This is part of the multithreading journey. The parser and lexer were using loads of global variables and all of these are now packed into struct cf_context and others. Note that the config API has changed: * cfg_alloc[zu]?(size) is now cf_alloc[zu]?(ctx, size) * cf_error(msg, ...) is now cf_error(ctx, msg, ...) * config_parse() and cli_parse() are now called differently * there is a brand new CF_CTX section in *.Y files which participates in struct cf_context construction
