* 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.)

* ft245r.c: Remove the reader thread (also removes
patch #9079)
Eliminate separate reader thread by tracking how many bytes are queued
in the FTDI chip's RX FIFO and reading those bytes when it fills up
(since in synchronous bitbang mode, the chip won't send any more bytes
until it has space in the RX FIFO). This reduces TPI programming time
by another 33%.
Since write data is now queued as much as possible, we need flush this
queued data (a) before reading and (b) before sleeping. For the
latter case, a new helper function ft245r_usleep() is introduced.

Submitted by David Mosberger-Tang:
Optimize TPI programming speed by reducing number of USB reads.
Specifically, when writing to the FTDI chip (without needing the data
it accumulates), simply increment a count of how many bytes the next
read should ignore. Thus, if there is one or more write followed by a
read, we only need to read from the device once.
Improves TPI programming speed by another factor of 2.

With newer versions of the Linux kernel (e.g., Ubuntu's
linux-image-4.4.0-75-generic), the default for the latency timer is
set to a high value. Since this driver needs quick turnaround times,
set it explicitly to the minium. This improves TPI programming speed
by almost a factor of 10.
