Driver 'openjtag' requires both libftdi and libusb1.
The current check is incorrect and the driver is built when
libftdi is present with libusb0 and without libusb1, which causes
the linker to fail resolving the required libusb1 symbols.

* configure: drop macro 'AC_HEADER_TIME'
The macro AC_HEADER_TIME has been obsoleted by autoconf 2.70.
Not all systems provide 'sys/time.h', plus some old system didn't
allowed to include both 'time.h' and 'sys/time.h' because 'time.h'
was included by 'sys/time.h' and was not properly protected to
allow multiple inclusion.
The macro AC_HEADER_TIME helps to detect such odd case.
Nowadays all the systems properly protect 'time.h', so its safe to
unconditionally include 'time.h', even if it is also included by
'sys/time.h'.
The case of systems without 'sys/time.h' is already covered by
configure.ac through the directive
AC_CHECK_HEADERS([sys/time.h])
Remove the obsoleted autoconf macro and simplify the code by
including 'time.h' unconditionally and check HAVE_SYS_TIME_H to
include 'sys/time.h'.

* jlink: fix device discovery when network is off
If user specifies a serial number for the jlink device, openocd
extends the search to network jlink devices too, without checking
if the host has a valid and functional network connection. If the
network is not functional, libjaylink returns error. This error
invalidates the discovery on USB, even if it was successful.
Factor-out parts of the jlink_init into separate jlink_open_device
function, use that function to firstly discover and match USB
devices and, if matching device was not found on the USB bus and
serial number was specified, repeat discovery and matching via TCP.

For HW threads other than current target, the registers in the

The original code passes to ->read_core_regs() and to
->read_xpsr() the pointer to the little-endian buffer reg.value.
This is incorrect because the two functions above require a
pointer to uint32_t, since they already run the conversion with
arm_le_to_h_u32() in the jtag callback.
This causes a mismatch on big-endian host and the registers get
read with the incorrect endianness.
Use an intermediate buffer to read the registers as uint32_t and
to track the destination reg.value pointer, then copy the value in
reg.value after the call to jtag_execute_queue().
Tested with qemu-armeb and an OpenOCD built through buildroot
configured for cortex-a7 big-endian.
Note that if jtag_execute_queue() fails, the openocd register
cache is not updated, so the already modified flags 'valid' and
'dirty' are incorrect. This part should be moved after the call to
jtag_execute_queue() too.

Real Time Transfer (RTT) is an interface specified by SEGGER based on
basic memory reads and writes to transfer data bidirectionally between
target and host.
Every target that supports so called "background memory access", which
means that the target memory can be accessed by the debugger while the
target is running, can be used.
RTT is especially of interest for targets which do not support Serial
Wire Output (SWO) (e.g. ARM Cortex-M0) or where using semihosting is
not possible (e.g. real-time applications) [1].
The data transfer is organized in channels where each channel consists
of an up- and/or down-channel. See [2] for more details.
Channels are exposed via TCP connections. One or more RTT server can be
assigned to each channel to make them accessible to an unlimited number
of TCP connections.
The current implementation does not respect buffer flags which are used
to determine what happens when writing to a full buffer.
Note that the implementation is designed in a way that the RTT
operations can be directly performed by an adapter (e.g. J-Link).

Reading of DPIDR is the very first operation after JTAG to SWD sequence.
Without this change if DPIDR read fails then swd connect fails.
Keep trying JTAG to SWD sequence and DPIDR read until success
or timeout 0.5 sec. It makes setting of adapter srst delay on SWD transport
mostly unnecessary.
Also test for ERROR_WAIT (which should not occur according to
IHI 0031E B4.3.2 but a quirk is known) and if bus is kept stalled
then issue abort to make the next connect possible.

If dap_dp_read_atomic() in 30 trials loop fails, dap->do_reconnect is set.
Following dap_dp_read_atomic() calls dap_queue_dp_read() which in case
of SWD transport calls swd_queue_dp_read(). It starts
with swd_check_reconnect() and it calls swd_connect() because
dap->do_reconnect is set. swd_connect() does some initialization,
reads DPIDR and calls dap_dp_init() again!
Moreover if dap_dp_init() is called from cortex_m_reset_(de)assert()
one level of recursion is necessary to reconnect the target.
Introduce dap_dp_init_or_reconnect() for use in cortex_m reset
and similar.
Remove loop of 30 atomic reads of DP_STAT to prevent unwanted recursion.

- rename and cleanup to arm-usb-ocd-h-cjtag file to be consistent
- add copy of olimex-arm-jtag-cjtag.cfg as arm-usb-tiny-h-cjtag.cfg
- did not remove olimex-arm-jtag-cjtag.cfg (should be deprecated)
