This feature has been designed with the sometimes quite flakey direct
(parallel or serial port attached) bitbang programming adapters in
mind that were quite common about two decades ago.
With parallel ports vanishing from modern PCs almost completely, and
the advent of various USB-attached low-cost programming devices,
this class of programmers disappeared almost completely.
Furthermore, the fuse combinations that were covered by the feature
are no longer around on all recent AVR devices, so for an ever
increasing number of devices, safemode already became meaningless and
was turned off anyway.
With the prospective version 7.x release, it's a good point in time to
introduce a major change like this one.
There's some confusion as the datasheet calls the device family
LGT8FX8P but the devices itself are LGT8F88P through LGT8F328P.
Obviously, the "X" is actually a wildcard denoting the flash size.
Integrate old INSTALL into README.md, both files had a lot
of (potential) overlap.
Add template for new entries in NEWS, targetting next release.
Bump version number to 6.99-20211218
Tentatively, with the Github migration and all ongoing code
restructuring, we aim for a version 7.0 release at some point
in the future.
In main.c, drop unused variable `fuses_specified'.
Variable ran out of service in r519, but never got removed.

* ft245r.c (ft245r_set_bitclock): add workaround for
FT245 hardware bugs in bitclock setting
Correct baud rate calculation (multiplying with factor of 2 was wrong)
and add compile-time workaround for FTDI chips suffering for the
variable pulse-width errata. The workaround entails always running
the chip at 3MHz and stuffing the channel with repeated bytes to
achieve the desired baudrate.
This has no effect on programming speed. Note, however, that now a
baudrate option -b750000 has to be used to achieve maximum speed.
(Option enabled by default now.)
