    Fix runtime errors when built with UBSan

    nopen.c:37:15: runtime error: left shift of 1 by 31 places cannot be
    represented in type 'int'
    nopen.c:39:18: runtime error: left shift of 1 by 31 places cannot be
    represented in type 'int'
    userdat.c:251:111: runtime error: left shift of 1 by 31 places cannot be
    represented in type 'int'

    There are lot of 1<<31 macro definitions in this repo, so I'm expecting a
    lot more of this type of fix to be required to make UBSan happy.

    Add FCLOSE_OPEN_FILE to close a FILE*, if it's open (non-NULL), and NULLify it

    Change CLOSE_OPEN_FILE to a do/while(0) to eliminate extraneous semicolon

    Log Message:
    Fix write-locks (deny-all/exclusive flocks) in sopen()

    SH_DENYRW (deny-all) locks were broken 18 years ago with commit b866f1990a.

    This fixes that by treating SH_COMPAT the same as SH_DENYNO (only), rather
    than the same as SH_DENYNO or SH_DENYRW (and performing no locking).

    This is likely the/a root-cause of some SBBS file corruption on *nix systems.

    Modified Files:
    src/xpdev/filewrap.h
    Log Message:
    Add FILE_RETRY_ERRNO() definition, to be used in sopen()/lock() loops

    Note: EBUSY was added to the list of errno values that should cause a retry
    as observed on Vertrauen, running sbbs-linux on a Samba mount, opening
    locked files can return failure (-1) with errno = EBUSY, e.g.
    evnt BBS Events !ERROR 16 (Device or resource busy) in logon.cpp line 616 (logonstats) reading "system stats" access=0

    This was apparently resolved by adding EBUSY (16) the values that trigger an sopen()
    retry (i.e. from [f]nopen()).

    Modified Files:

    Log Message:
    Retry file lock/read operations on EIO errors

    As seen on MacOS, an SMB shared file can cause the Mac SMB client to report EIO error on locked-file read or lock attempts. So retry.
