Remove a use of AH_BOTTOM from configure.ac. This macro is used by
autoheader to add '#include' of some include file to the end of
config.h.in and then to config.h. OpenOCD can be built with a custom
config.h, so it's preferable to move these '#include' statement directly
in the C files that need them dropping this unneeded dependency.
It also causes problems when I want to use the gnulib library (which
comes with its own Makefile, and does not have the same include path as
the top-level Makefile).
So this change touches a lot of files, but is actually really simple. It
does not affect functionality at all.

Each one of CMSIS-DAP command handlers was responsible for setting
HID report number, which in case of USB bulk transport was not used
at all. The command had to be filled with 1 byte offset whereas
the response was read without an offset.
Introduce 'command' and 'response' pointers into struct cmsis_dap.
Use them for filling the command and read the response respectively.
CMSIS-DAP command parameter are now at positions as documented in
https://arm-software.github.io/CMSIS_5/DAP/html/group__DAP__Commands__gr.html
Adjust buffer allocation for HID and USB bulk transports.
While on it, use h_u32_to_le() and h_u16_to_le() instead of per-byte
writes.

The hidapi cmsis-dap backend is using a packet_size of
64+1: 64 is the bMaxPacketSize0 and 1 is the hid Report-Id.
In hidapi::hid_write(), the packet_size is decremented by 1 and
stored for the next transfer.
The packet_size is now valid bMaxPacketSize0=64,
so when hid_read() is called, libusb_bulk_transfer() finishes w/o timeout.
For the libusb bulk backend, the same packet_size of 64+1 is used,
but there's no hid_write() to decrement and store it for the next read.
So the next time a read is done, it will try to read 64+1 bytes.
Fix this by putting the packet logic within each backend.
Use calloc() to allocate the struct cmsis_dap to be on safer side.

This change implements CMSIS-DAP v2 which works with raw USB bulk transfers.
The old driver is now split into a generic CMSIS part and a HID backend,
with a new raw USB backend for CMSIS-DAP v2.
New commands:
- cmsis_dap_backend (usb_bulk | hid | auto)
- cmsis_dap_usb interface <interface number>
