    Log Message:
    Create a Win32 wrapper for mkstemp() as MSVC doesn't have it

    SBBSecho uses mkstemp() now (instead of tempnam()) - so we need this POSIX function wrapper for Windows builds to succeed.

    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()).
