Oswald Buddenhagen 42f165ecf7 fix UIDNEXT query vs. concurrent imap_fetch_msg()
the uidnext query following message stores can be interleaved with
message fetches. that means that we cannot rely on the 1st command in
flight being that query. but instead of iterating over all commands in
flight, move the uidnext query flag to imap_store (and make sure to
check for the presence of a message body before testing it) - this
avoids the loop and an extra byte in every command.

this also makes it clear that the query is mutually exclusive with
loading messages (the untagged responses are not distinguishable).

isync/mbsync - free (GPL) mailbox synchronization program
http://isync.sf.net/

See AUTHORS for contact information.

``mbsync'' is a command line application which synchronizes mailboxes;
currently Maildir and IMAP4 mailboxes are supported. New messages, message
deletions and flag changes can be propagated both ways.
``mbsync'' is suitable for use in IMAP-disconnected mode.

Synchronization is based on unique message identifiers (UIDs), so
no identification conflicts can occur (unlike with some other mail
synchronizers).
Synchronization state is kept in one local text file per mailbox pair;
these files are protected against concurrent ``mbsync'' processes.
Mailboxes can be safely modified while ``mbsync'' operates.
Multiple replicas of each mailbox can be maintained.

isync is the project name, while mbsync is the current executable name; this
change was necessary because of massive changes in the user interface.

* Features

    * Fine-grained selection of synchronization operations to perform
    * Synchronizes single mailboxes or entire mailbox collections
    * Partial mirrors possible: keep only the latest messages locally
    * Trash functionality: backup messages before removing them
    * IMAP features:
	* Supports TLS/SSL via imaps: (port 993) and STARTTLS
	* Supports SASL for authentication
	* Pipelining for maximum speed

* Compatibility

    isync should work fairly well with any IMAP4 compliant server;
    servers that support the UIDPLUS and LITERAL+ extensions are most
    efficient.

    Courier 1.4.3 is known to be buggy, version 1.7.3 works fine.

    M$ Exchange (2013 at least) needs DisableExtension MOVE to be compatible
    with the Trash functionality.

* Platforms

    At some point, ``isync'' has successfully run on:
    Linux, Solaris 2.7, OpenBSD 2.8, FreeBSD 4.3.

* Requirements

    perl v5.14+
    Berkeley DB 4.1+ (optional)
    OpenSSL for TLS/SSL support (optional)
    Cyrus SASL (optional)
    zlib (optional)

  The build from git also requires:

    GNU autotools (autoconf & automake)
    perl module Date::Parse (libtimedate-perl on Debian, perl-TimeDate on
                             Fedora and Suse)

* Installation

    ./autogen.sh (only when building from git)
    ./configure
    make
    sudo make install

* Help

    Please see the man page for complete documentation.
