Log Message:
alpine: Update to 2.25.

pkgsrc changes and notes:

- According to the release notes, this fixes CVE-2021-38370 by
  Damian Poddebniak.
- I have added the maildir patch, as FreeBSD does, because it seems
  useful.
- I have removed the non-trivial patch for OpenBSD, because going by
  OpenBSD's ports repository it's no longer necessary at all.

   Version 2.25 includes several new features and bug fixes.

   Additions include:
     * Unix Alpine: New configuration variable ssl-ciphers that allows users
       to list the ciphers to use when connecting to a SSL server. Based on a
       collaboration with Professor Martin Trusler.
     * New hidden feature enable-delete-before-writing to add support for
       terminals that need lines to be deleted before being written. Based on
       a collaboration with Professor Martin Trusler.
     * Experimental: The instruction to remove the double quotes from the
       processing of customized headers existed in pine, but it was removed
       in alpine. Restoring old Alpine behavior. See this
     * Add the capability to record http debug. This is necessary to debug
       XOAUTH2 authentication, and records sensitive login information. Do
       not share your debug file if you use this form of debug.
     * Remove the ability to choose between the device and authorize methods
       to login to outlook, since the original client-id can only be used for
       the device method. One needs a special client-id and client-secret to
       use the authorize method in Outlook.
     * PC-Alpine only: Some service providers produce access tokens that are
       too long to save in the Windows Credentials, so the access tokens will
       be split and saved as several pieces. This means that old versions of
       Alpine will NOT be able to use saved passwords once this new version
       of Alpine is used.
     * PC-Alpine: Debug files used to be created with extension .txt1, .txt2,
       etc. Rename those files so that they have extension .txt.
     * Always follow â**suppress-asterisks-in-password-promptâ** setting in
       the various password prompts. Submitted by Étienne Deparis.
     * Use 'alpine -F' instead of 'pine -F' as the browser default pager.
       Submitted by Étienne Deparis.
     * Introduction of OTHER CMDS menu for the browser/pilot to let people
       discover the two new commands: "1" is a toggle that switches \ 
between 1
       column and multicolumn mode. The "." command toggles between \ 
hiding or
       showing hidden files, and the "G" command to travel between
       directories. Contributed by Étienne Deparis.
     * Add option -xoauth2-flow to the command line, so that users can
       specify the parameters to set up an xoauth2 connection through the
       command line.
     * Alpine deletes, from its internal memory and external cache, passwords
       that do not work, even if they were saved by the user.
     * New format for saving passwords in the windows credential manager for
       PC-Alpine. Upon starting this new version of Alpine the passwords
       saved in the credential manager are converted to the new format and
       they will not be recognized by old versions of Alpine, but only by
       this and newer versions of Alpine.
     * Enabled encryption protocols in PC-Alpine are based on those enabled
       in the system, unless one is specified directly.

   Bugs that have been addressed include:
     * The c-client library parses information from an IMAP server during
       non-authenticated state which could lead to denial of service.
       Reported by Damian Poddebniak from Münster University of Applied
       Sciences.
     * Memory corruption when alpine searches for a string that is an
       incomplete utf8 string in a local folder. This could happen by
       chopping a string to make it fit a buffer without regard to its
       content. We fix the string so that chopping it does not damage it.
       Reported by Andrew.
     * Crash in the ntlm authenticator when the user name does not include a
       domain. Reported and fixed by Anders Skargren.
     * When forwarding a message, replacing an attachment might make Alpine
       re-attach the original attachment. Reported by Michael Traxler.
     * When an attachment is deleted, the saved message with the deleted
       attachment contains extra null characters after the end of the
       attachment boundary.
     * Tcp and http debug information is not printed unless the default debug
       level is set to 1. Print this if requested, regardless of what the
       default debug level is.
     * When trying to select a folder for saving a message, one can only
       enter a subfolder by pressing the ">" command, rather than \ 
the normal
       navigation by pressing "Return". Reported by Ulf-Dietrich Braunmann.
     * Crash when attempting to remove a configuration for a XOAUTH2 server
       that has no usernames configured.
     * Crash caused by saving (and resaving) XOAUTH2 refresh and access
       tokens in PC-Alpine. Reported by Karl Lindauer.
