Log Message:
Update alpine to 2.22.

Additions include:

  * Support for XOAUTH2 authentication method in Gmail.
  * PC-Alpine builds with LibreSSL and supports S/MIME.
  * NTLM authentication support with the ntlm library, in Unix systems. Based
    on code provided by Maciej W. Rozycki.
  * Add /tls1_3 flag for servers that support it. Read more information in the
    secure protocols help.
  * To increase user's privacy, remove phone-home code that would prompt users
    to send an email message upon starting Alpine for the first time for
    purposes of counting. Your use of Alpine does not disclose information
    about you or your use of Alpine to the developers of Alpine.
  * New variable encryption-protocol-range that allows users to configure
    versions of the SSL/TLS protocol that Alpine is restricted to try when
    establishing a secure connection SSL/TLS to a remote server. The default
    can be set at compilation time.
  * Add -dict option to PC-Pico, which allows users to choose a dictionary when
    spelling. Sample usage: -dict "en_US, de_DE, fr_FR".
  * Improvements to the configure stage of compilation. Some of these
    contributed by Helmut Grohne. See Bug 876164 in Debian.
  * Add "remove password" command to the management screen for the password
    file encryption key. This allows users to use their password file without
    entering a master password.
  * Add the "g" option to the select command that works in IMAP \ 
servers that
    implement the X-GM-EXT-1 capability (such as the one offered by Gmail.)
    This allows users to do selection in Alpine as if they were doing a search
    in the web interface for Gmail.
  * New variable close-connection-timeout, which tells Alpine to close a
    connection that is having problems being kept alive after the number of
    seconds configured in this variable, if the connection has not recovered.
    The default is 0, which means to keep the connection alive and wait for the
    connection to recover.
  * When a message is of type multipart/mixed, and its first part is multipart/
    signed, Alpine will include the text of the original message in a reply
    message, instead of including a multipart attachment. Suggested by Barry
    Landy.
  * S/MIME: Some clients do not transform messages to canonical form when
    signing first and encrypting second, which makes Alpine fail to parse the
    signed data after encryption. Reported by Holger Trapp.
  * Add /auth=XYZ to the way to define a server. This allows users to select
    the method to authenticate to an IMAP, SMTP or POP3 server. Examples are /
    auth=plain, or /auth=gssapi, etc.
  * Add backward search in the index screen. Based on patch by Astyanax Foo,
    submitted in 2009, but resubmitted by Erich Eckner on 2019.
  * SMIME: When Alpine is set to validate a message using the user's store, and
    user agrees to save a certificate of another user, use the saved
    certificate immediately to verify the smime message. Reported by Stefan
    Mueller.
  * Do not use a delay when printing messages to screen when the initial
    keystroke sequence of commands is active. Based on a report from Holger
    Trapp.
  * In PC-Alpine, when the decoded name of an attachment does not agree with
    its encoded name, Alpine will offer to save the file using the UTF8 encoded
    name.

Bugs that have been addressed include:

  * Width of characters is not always determined correctly when wcwidth is
    used. Revert to using code for the Windows operating system. Reported by
    Andrew Ho.
  * The call realpath(..., NULL) gives an error in Solaris, which means that we
    need to allocate memory for storing the resolved path. Reported by Fabian
    Schmidt.
  * Crash when attempting to bounce a message due to lack of space in allocated
    space for key menu array. Reported by David Sewell.
  * Crash when a CA certificate failed to load, and user attempted to view
    certificate information of other certificate authorities.
  * Crash in the S/MIME configuration screen when a user turned off S/MIME, and
    then re-enabled it. Also crash when attempting to enter the S/MIME
    configuration screen if S/MIME was turned off.
  * Deactivate some color code from Pico (as standalone editor in the windows
    version) until I find a way to activate it again. This is not critical and
    it is not something that PC-Pico must have (some of it already exists in
    other ways, like color support, what does not exist is the more complex
    code that Unix-Pico has with color codes for specific colors.)
  * When a message is multipart, and the first part is flowed text, then
    forwarding the message will set the first part to be flowed, and sent that
    way even when the option Do Not Send Flowed Text is enabled. Reported by
    Holger Trapp.
  * When a message/rfc822 part of a message is encoded with
    Content-Transfer-Encoding: QUOTED-PRINTABLE, Alpine will stop processing
    that message. Later this causes Alpine to crash because when it displays
    messages, it assumes that both header and body parts are processed.
    Reported by Mark Crispin in 2010, in the Alpine-info list (message with
    subject "crash bug in alpine/mailpart.c:format_msg_att()") with no \ 
example,
    and reported now by Holger Trapp, with an example.
  * In addition to the previous report, Alpine encodes message/rfc822 messages
    as QUOTED-PRINTABLE, in contradiction with RFC 2045, when it receives a
    report that its encoding is 8bit. We preserve the encoding reported by the
    IMAP server, and do not encode in QUOTED-PRINTABLE.
  * Update build.bat file to add /DWINVER=0x0501 so that Alpine can build when
    using Visual Studio 2017. Fix contributed by Ulf-Dietrich Braunmann.
  * When the locale is not set up to UTF-8, alpine might determine the width of
    a character incorrectly. Reported by Alexandre Fedotov.
  * In some rare cases, when attachments are deleted before saving emails, the
    filenames will be displayed in RFC1522 representation, instead of in
    decoded form. Reported and patched by Wang Kang.
  * When colors are edited from the main setup configuration screen, some color
    settings are not updated until Alpine is restarted. Reported by Andrew
    Hill.
  * If the first part of a message is multipart/alternative, and the first part
    of this is also a multipart type, then Alpine might fail to select the
    first text part when replying to a message. Reported by Lucio Chiappetti.
  * TLS 1.2 works does not work if Alpine is compiled with openssl >= 1.1.0.
    Reported and patched by Kyle George.
  * If the directory where Alpine saves the certificates is empty, alpine would
    not create a self-signed certificate to encrypt the password file.
  * S/MIME: The list of public certificates is freed before it is reused when a
    signature fails to verify. This causes Alpine to crash. Patch submitted by
    Linus Torvalds.
  * S/MIME: A message could fail to verify its signature even if the
    certificate was saved when the message was open. Based on a report by David
    Woodhouse to the RedHat bugzilla system.
  * When there are time changes in the clock, Alpine might go to sleep for big
    amounts of time while displaying messages in the screen. Reset sleep time
    to 5 seconds in case it finds it needs to sleep more than 5 seconds or a
    negative amount of time.
  * Restore recognition of empty directories. It was deleted by mistake when
    added support for internationalization in folders. Based on a report by
    Michael Rutter.
  * Alpine stops parsing the mailcap file when it finds an invalid entry.
    Reported by Matt Roberds to the Debian bug system at https://
    bugs.debian.org/cgi-bin/bugreport.cgi?bug=886370.
  * Crash with error "Lock when already locked" when an attempt to \ 
check for
    new mail on a locked stream that is being used for a save operation.
    Reported by Carlos E.R.
  * Alpine removes trailing spaces from passwords, making a longin attempt
    fail. Reported by R. Lyons.
  * Alpine crashes when opening a remote imap folder and computing scores.
    Reported by Paul DeStefano.
  * When more than one server was given in the server-name configuration option
    of rldap servers, none of them worked. Reported by Robert Wolf.
