ipdbg: improve ipdbg-host speed
By queuing multiple jtag transfers the connection speed between
JTAG-Host and JTAG-Hub is improved. This is due to much less
calls to OS functions. An improvement of about x30 has been
measured with ftdi-based jtag adapters
For this to work the JTAG-Host server needs to know if flow control
is enabled on the JTAG-Hub ports. This is possible with newer
JTAG-Hub/JtagCDC. For old JTAG-Hubs the queuing is not enabled so
this change is backwards compatible.
