Refactor package errors + packages names :

- Refactor ErrorType, list errors managment, codeError
- Add interface Error with error interface implement
- Add type CodeError assign typiclly to const that represent code of error
- Add func to registry func to retrieve message from an uint16 codeError (typicaly a switch of each codeError const)
- Add default errorCode with default errorMessage if no one code or message is found
- Add modeError to manage how to manage compatibility between Error interface and error interface
- Add Error interface that allow parent link (parent as error or Error interface), code and trace management
- Add trace finder to allow find func/file/line caller when Error is call
- Add http 2 transport in httpcli
- Add http 2 transport in httpserver
- Add function to get client http with timeout management in httpcli
- Add function to get Error if occurs of http client in httpcli
- Add test for smtp package
- Chg return error by returning Error in all packages
- Chg package njs-archive by archive
- Chg package njs-certif by certificates
- Chg package njs-console by console
- Chg package njs-crypt by crypt
- Chg package njs-errors by errors
- Chg package njs-httpcli by httpcli

- Chg package njs-semaphore by semaphore
- Chg package njs-smtp by smtp
- Chg package njs-static by static
- Chg package njs-status by status
- Chg package njs-version by version
- Fix dependancies gopkg by github/go-ldap for go module compatibility
- Fix gin Abort call by gin Abort with Error in static package
