Subject: Increase max password length to handle oauth tokens
Git-repo: https://gitlab.com/fetchmail/fetchmail.git
Git-commit: 6e877b5d92527ad501aaef46e37704b51db316fb

The maximum length of oauth2 access tokens is unbounded.
* Google uses 2048 byte access tokens and "Google reserves the right
  to change token size within these limits, and your application
  must support variable token sizes accordingly."
* My Office365 access token is 2108 bytes long.
* Intuit says you must support 4096 byte access tokens.

This simply patches the hard-coded limit to 4096 bytes, but it might
not be sufficient.
