Provide a way to get the MSGFLAG's from the bitwise built PR_MESSAGE_FLAGS

[bkram]

For instance when a PR_MESSAGE_FLAGS contains 17 (0x11L)

This should return [MSGFLAG_HASATTACH, MSGFLAG_READ]

[bkram]

For now I have created a workaround

def get_pr_message_flags(pr_message_flags):

    flags = []
    msgflags = [('MSGFLAG_READ', 0x0001), ('MSGFLAG_UNMODIFIED', 0x0002), ('MSGFLAG_SUBMIT', 0x0004),
                ('MSGFLAG_UNSENT', 0x0008), ('MSGFLAG_HASATTACH', 0x0010), ('MSGFLAG_FROMME', 0x0020),
                ('MSGFLAG_ASSOCIATED', 0x0040), ('MSGFLAG_RESEND', 0x0080), ('MSGFLAG_RN_PENDING', 0x0100),
                ('MSGFLAG_NRN_PENDING', 0x0200)]

    while len(msgflags) > 0:

        flag = msgflags.pop()

        if pr_message_flags - flag[1] >= 0:
            pr_message_flags -= flag[1]
            flags.append(flag[0])

    return flags

print get_pr_message_flags(0x3FF)
