v0.8.3

[epilys]

Fixes and enhancements

• Add extra_submission_headers option to support posting to Newsgroups (which need a Newsgroup header).
• Show error description when TIOCGWINSZ fails (i.e. we are not in a TTY).
• Add QUIT command to SMTP transactions (Andrei Zisu @matzipan)
• Fix SMTP end sequence (Andrei Zisu @matzipan)
• Fix date formatting in conversations index style.
• Replace splice with truncate in melib/imap, which was hurting performance.
• Update yanked ahash dependency.
• Removed pcre2 dependency from default features.
• Removed managesieve-client from shipped binaries, it was included by accident before.
• Add static feature and make it default: TLS libraries, libcurl, libsqlite3, libz, and libdbus are now vendored by default eliminating the need for system dependencies.
• Replace CRLF to LF when editing a draft in the composer.
