ngxlogex

Extended usage for ngx.log, accepts table as parameter now;
Tail call is used to avoid stack depth increase, overhead is very small.
Judged loglevel inside log function, which avoids table serialization on non-printed logs.

`require' once in init/init_worker, and use anywhere, not necessary to require in every module

Old usage:
ngx.log(ngx.DEBUG, json.encode( { aaa=1, bbb='jklmn'} ) )

New usage:
require 'ngxlogex' -- require once in init/init_worker, and use anywhere, not necessary to require in every module
ngx.log(ngx.DEBUG, { aaa=1, bbb='jklmn'})

ngx.debug({ aaa=1, bbb='jklmn'})

ngx.info(...)
ngx.notice(...)
ngx.warn(...)
ngx.error(...)
ngx.crit(...)
ngx.alert(...)
ngx.emerg(...)

Use `inspect' for serialization:
local inspect = require 'inspect'
require 'ngxlogex'.init({ table = inspect }) -- require+init once in init/init_worker, and use anywhere
