master e78c15a 5/8: Drop unnecessary backward compatibility aliases

[Jonas Bernoulli]

branch: master
commit e78c15acf679259caea6566446f61966cea032aa
Author: Jonas Bernoulli <jonas@bernoul.li>
Commit: Jonas Bernoulli <jonas@bernoul.li>

    Drop unnecessary backward compatibility aliases
    
    We can assume that `encode-coding-string' and `decode-coding-string'
    are available; they were added in 1997.
    
    * lisp/epa-file.el (epa-file--encode-coding-string)
    (epa-file--decode-coding-string): Remove aliases for
    encode-coding-string and decode-coding-string.
    * lisp/epa-file.el (epa-file-write-region): Use encode-coding-string
    instead of removed epa-file--encode-coding-string.
