When using the MSVC2017 CRTL, a lock() of a region that was previously
locked is a blocking call causing major slowness in the MSVC2017 build.
This just reverses the 1-line commit from 16 years ago in rev 1.10 of this file.

Most of the copyright years in the source code were misleading (the date of
most recent publish was actually later) and all were unnecessary. I've been
removing copyright years piecemeal, for a long time, but I decided it was time
to just perform a bulk search and (mostly) replace. In some cases, I left
old copyright years on files that either are not used (and soon to be removed)
or obsolete and unlikely to ever be touched again (e.g. Win9x FOSSIL VXD). Some
of the runtime binaries still contain copyright years and those were updated to
2018.

lock across things with timeouts in them, but since if another thread has
the file locked we shouldn't be fillding with it anyway, this should be
fine.

Fixes weird (and relatively rare) timing issues with node.dab accesses on a
many core host.

New Features:
- Multiple bindings for each service
  Use comma-separated interfaces on Interface= lines in the ini file.
  Default is now "0.0.0.0,::"
- IPv6 support
- TLS support for the webserver and (non-static) services
  New TLS option in services.ini (ie: Options=TLS)
- Decrease LEN_SCAN_CMD to 35 chars, increase the CID field to 45 chars,
  and rename the MAIL_CMD string to IPADDR.  I think this frees up the
  note field for SysOp use.

Changed putnode to retry writing up to 10 times before erroring out - hopefully solving EDEADLK problem with Linux/smbmount/Win2K server.

This change was needed for compatibility with the Linux Samba client. :-(
 (SS_NODEDAB, nodefile_fp, and node_ext_fp are no longer used).
