http_engine

provide stdlib for:

• request path & type mapper
• request handler with sql-ex lang
• json support

the http-lib should run at backend, when executed the part, just open a thread at backend to handle requests, until the main process(repl engine or executor process) exited.

and it will show logs to stdout when handle request, and can be set to be silent.

also, support interactions with other stdlib components, like run sql from http content using db_engine, storage content to filesystem, and string process using io_engine, data manipulation using data_engine, etc.

db_engine

this part is standard sql database support, supporting acid actions and some dbms features

now I'm planning support higher query process like join, groupby, etc., and core features like transactions, views, permission control.
