Almost the same as the LM4F120 LaunchPad but the chip is using the new
naming scheme (Tiva C series), supports USB OTG and has some new PWM
hardware blocks.

Create a single pair of relatively simple functions to handle all variants
of MEM-AP transfers. This replaces the many separate functions that
handled different access sizes and packed or non-packed transfers, which
were all implemented rather differently.
With this single implementation, performance should be more consistent,
regardless of transfer type.

Accessing one byte of memory using a 16-bit access is not well defined.
The current implementation is forgiving and rounds up, but it should not
be relied upon.
Also, I suspect this code might fail if the byte order differs between
target and host, but I have no way of verifying it so I left it as it is.

The word count returned from max_tar_block_size() was compared with the
count of half-word/bytes in the u16 and u8 packed access functions,
causing an infinite loop if the access actually crossed the boundary.
Change max_tar_block_size() to return a byte count, and scale at the call
site.

For packed and/or unaligned accesses, the write functions reordered the
source buffer in place. Causing in the best case a segfault, in the worst
case silent data corruption.
Rewrite the data fetching to directly match the byte lane mapping
according to IHI0031C, without destroying the buffer.
Also slightly clean up variable usage and harmonize all the write
functions.

Previously, when doing EMU_CMD_HW_JTAG3 commands we would do two reads,
one to read the data, and one to read the result. However, we can just
do a single larger read instead.
The motivation for this change is a weird problem. If I run the Segger
software before running OpenOCD, then the first read always fails:
Error: usb_bulk_read failed (requested=1, result=0)
Error: jlink_tap_execute, wrong result -107 (expected 1)
Sniffing the USB traffic shows that the J-Link is returning an
overflow error, meaning it is expecting to return the full result
in a single read.

Due to issues reported when using the jtag mode of the stlink (see Trac #61),
the functionality/checking has been moved to the driver.
This change also fixes unaligned 32bit memory read/write for the stlink.
From testing this change also brings a 3KiB/s speed increase, this is due
to the larger read/write packets.
