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.

C99 / stdint.h has basically already been required before, as types
like uint8_t are in use in a number of other locations throughout the
source.

This avoids potential divisions by 0, and possibly also other mistakes
in case of malformed avrdude.conf entries.
The solution is different than the one in patch #9820 but is supposed
to cover that condition as well.
