commit 81067a5544c94e7fb7146c2c921469fcc5b5aebf
Author: Ben Pfaff <address@hidden>

    zip-reader: Improve error messages.
    
    With this change, the zip-reader's error messages always include the zip
    file name and, when relevant, the member name.  Otherwise it wasn't always
    clear what a message liek "No such file or directory" was talking about.

commit c39f02a7c1d95a2c7474a8b86c33e609a01c66e1
Author: Ben Pfaff <address@hidden>
Date:   Sat Jul 15 20:41:08 2017 -0700

    zip-reader: New function zip_reader_get_member_name().
    
    This allows the caller to obtain a list of .zip members.

commit a7c2f3dc0e04370417f765e4b3f0e8b575d02d89
Author: Ben Pfaff <address@hidden>
Date:   Sat Jul 15 20:26:31 2017 -0700

    zip-reader: Don't keep .zip file open for lifetime of zip_reader.
    
    The zip_reader no longer uses the .zip file after it opens it, so close it
    when it's no longer needed.

commit db7d86c511e47ccbf28263889c8060fd3a97edbc
Author: Ben Pfaff <address@hidden>
Date:   Sat Jul 15 20:22:10 2017 -0700

    zip-reader: Read the whole central directory at .zip open time.
    
    By reading the whole central directory when we open the .zip file, rather
    than one entry at a time, we make it easier to get a list of entries and
    make it available to the client.  (This will be implemented in an upcoming
    commit.)
    
    This commit also fixes memory leaks in the error case in zip_member_open().
    
    This commit also changes the usage model.  Previously, if the caller opened
    a single member more than once, all the members shared a single copy of
    the member and read each other's data.  Now, each caller that opens a
    member gets a separate copy and a separate file pointer.  Callers now need
    to call zip_member_finish() when they're done with a member.
    
    With this commit, the code only keeps an open FILE for a member if the
    caller opened that member.  Previously, it kept an open FILE for any
    member that had been encountered.

    zip-reader: Fix memory leak on error path in zip_reader_create().

commit b9ccea9860d7123988968605f526a288f27f7544
Author: Ben Pfaff <address@hidden>
Date:   Sat Jul 15 16:47:34 2017 -0700

    zip-reader: Better hide implementation details from clients.
    
    By integrating the "inflate" code with the zip reader code, it is no
    longer necessary to expose the zip_member or decompressor details.
