    matchuser() now always returns 0 when passed an empty 'name'

    Also, don't match against deleted (blank) usernames in name.dat
    (e.g. when 'name' value consists of a single ETX character).

    Log Message:
    Don't truncate a user's record if the default download protocol or gender are '\0'

    A blank download protocol field in a user.dat, when parsed, sets the 'prot' field
    of user_t to 0. When writing the record back to the user.dat, this would prematurely
    truncate all other fields off the user record (since strings in C are NUL terminated
    and we're using sprintf() to format the record and %c specifier for that field).

    The fix is to write a ' ' character instead of '\0' if the user_t.prot is '\0'. As part of this fix, I'm writing a '?' if a user_t.sex is '\0' (not sure if this
    is actually possible, but just as insurance). Those are the only 2 single-character
    user properties/fields today.

    Bug reported/debugged by Al of The Rusty Mailbox (1:153/757.2) - thank you!

    The NoAccess* text.dat strings are not appropriate 'reason' codes

    These text.dat strings require an argument (and normally used with the NOACCESS @-code which uses the noaccess_str and noaccess_val member variables), so not appropriate to use as a reason code here. Use more generic (no argument) text.dat item numbers instead.

    More strict login-by-user-number support (parsing logic)

    Before now, if the sysop enabled login-by-user-number and the specified login ID *started* with a decimal digit, it'd be treated as a user number and converted to a 32-bit integer. This could result in weird stuff, like this error I got today:
    SMTP ... !ERROR -2 getting data on user (7000401005.gc7gg@synchro.net)

    7,000,401,005 is clearly greater than the number of users in my user base
    on Vert, but since 7B is > 2.1B (0x7fffffff), the number would be parsed as
    a *negative* integer value and thus less than the total number of users in my userbase.

    An obvious solution would be to just turn of login-by-user-number, and for
    most systems, I suggest doing that (a system is less secure with it enabled).

    However, I want to leave the option for sysops (at least for now) and don't want this weird behavior so, a login by user number now requires that the entire login ID is just decimal numbers, nothing else, and the number is
    parsed as an unsigned integer. So yes, roll-over can happen for very high numbers (>4.2B), but in no instance will the number be parsed as negative and thus lead to an invalid user record look-up attempt.

    The "user" directory is special: you don't need "access" to download from it.

    When sending a user-to-user file transfer, SBBS (since v3.19) will check that the file recipient will be able to download it (e.g. doesn't have restrictions preventing it) and this was failing for most (non-sysop) recipient users since they wouldn't normally meet the "access restrictions" of the user directory
    (by design).

    Fix getnodedat() error handling and usage

    If a file descriptor is passed to getnodedat() and the lock retry counter was reached, the file would be closed, but the passed file descriptor reference would not be set to -1. This could result in exceptions (from subsequent read attempts on the referenced file descriptor) in cases where the node.dab could not be locked or read by getnodedat() and was thus closed.

    The set/get_node_* helper functions (used by MQTT) were not initializing the node.dab file descriptor (i.e. to -1), so it's possible getnodedat() could
    try to read from and close an invalid/wrong open file descriptor. If the local variable happened to be initialized to a value <= 0, then, no problem, but
    this is undefined behavior (UB).
