Generate lists and use symbols in --libcurl code output.
This patch improves the output of curl's --libcurl option by generating code which builds curl_httppost and curl_slist lists, and uses symbolic names for enum and flag values. Variants of the my_setopt macro in tool_setopt.h are added in order to pass extra type information to the code-generation step in tool_setopt.c. If curl is configured with --disable-libcurl-option then the macros call curl_easy_setopt directly.
