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:
src/xpdev/filewrap.h
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.
