Size parameter is a nonsence that may happen e.g. if you

Use calloc() instead of malloc() as multiplication
count * sizeof(uint32_t) overflows for size >= 0x40000000.

This commit contains a rewrite of the jtagspi protocol and covers both
changes in the jtagspi.c openocd driver and the bscan_spi
(xilinx_bscan_spi) proxy bitstreams. The changes are as follows:
1. Always perform IR scan to ensure proper clearing of BYPASSed DRs.
2. Insert alignment cycles for all BYPASSed TAPs:
The previous logic was erroneous. The delay in clock cyles from a bit
written to the jtag interface to a bit read by the jtag interface is:
* The number of BYPASSed TAPs before this (jtagspi) tap
* The length of the jtagspi data register (1)
* The number of BYPASSed TAPs before this one.
I.e. it is just the number of enabled TAPs. This also gets rid of the
configuration parameter DR_LENGTH.
3. Use marker bit to start spi transfer
If there are TAPs ahead of this one on the JTAG chain, and we are in
DR-SHIFT, there will be old bits toggled through first before the first
valid bit destined for the flash.
This delays the begin of the JTAGSPI transaction until the first high bit.
4. New jtagspi protocol
A JTAGSPI transfer now consists of:
* an arbitrary number of 0 bits (from BYPASS registers in front of the
JTAG2SPI DR)
* a marker bit (1) indicating the start of the JTAG2SPI transaction
* 32 bits (big endian) describing the length of the SPI transaction
* a number of SPI clock cycles (corresponding to 3.) with CS_N asserted
* an arbitrary number of cycles (to shift MISO/TDO data through
subsequent BYPASS registers)
5. xilinx_bscan_spi: clean up, add ultrascale
This is tested on the following configurations:
* KC705: XC7K325T
* Sayma AMC: XCKU040
* Sayma AMC + RTM): XCKU040 + XC7A15T, a board with integrated FTDI JTAG
adapter, SCANSTA JTAG router, a Xilinx Ultrascale XCKU040 and a Xilinx
Artix 7 15T. https://github.com/m-labs/sinara/wiki/Sayma
* Custom board with Lattice FPGA + XC7A35T
* CUstom board with 3x XCKU115-2FLVA1517E

When listening on port 0, the system will assign a random open port. We
use this to run multiple OpenOCD instances against multiple simulators
as part of regression testing. This mechanism means the various test
instances don't have to coordinate to ensure they don't reuse any ports.
The required changes are minimal:
1. Don't increment the port number when it's 0.
2. Print out which port was assigned by the system.

Fixed a bug in stlink_usb_read_mem/write_mem preventing large data transfers
The SWIM support in stlink_usb was basically non existent so I have
implemented the missing parts. The bCBWCBLength and dCBWDataTransferLength
for STLINK-V1 protocol was not correct so that was fixed. The reason for
adding SWIM support is to add STM8 support for OpenOCD.
I have tested the driver on:
STM8 discovery board with the built-in STLINK-V1
STM8 discovery board with STLINK-V2 dongle
STM32 vldiscovery board with the built-in STLINK-V1
STM32F1xxx processor with STLINK-V2 dongle
