Is your feature request related to a problem? Please describe.

有大神反應"驗證權限"的部分希望可以直接用 c-code.
go-pttbbs 的 strategy 是跟 c-pttbbs 盡量 1-1 mapping.
所以大致上是可行的～

A clear and concise description of what you want to happen.

目前需要釐清:

1. 有哪些是希望直接使用 c-code.
2. 兩邊的 variables 要如何互相 share / copy.

這個 issue 將 list 出需要直接使用 c-code 的部分. 並且記錄相對應的 input/output 的對應.

A clear and concise description of any alternative solutions or features you've considered.

There are global variables in c-pttbbs (cuser and currboard).

It's better to refactor c-pttbbs to have pure functions (functions without global variables)
for the permission checking.
