If the target is not examined, many internal data required for the
gdb connections are not ready nor allocated. This causes OpenOCD
to hit a segmentation fault.
After the execution of the gdb-attach event handler, check if
target has been examined and eventually return error to refuse the
gdb connection.
Plus, since OpenOCD does not implements non-stop mode yet, gdb
expects the target to be halted by the inferior when the
connection is established.
Print a warning to inform the user in case the target is not
halted, but still accept the gdb connection to permit the
non-intrusive memory inspection with gdb, as explained in
http://openocd.org/doc/html/GDB-and-OpenOCD.html#gdbmeminspect

If a target is not examined when the debugger tries to connect to it
then it can lead to undesired/undefined behavior.
In particular it leads to a zero pointer dereference on the aarch64.

As the comment states, the 'init' command is issued before the
command 'dap apsel', otherwise it fails.
This dependency has been already fixed in commit e48690cb26
("target/arm_adi_v5: allow commands apsel and apcsw during init
phase"), so the command 'dap apsel' can now be issued directly.
Remove both the unneeded 'init' command and the comment that

By default GDB timeouts after 2 seconds, even if this value can be
modified with GDB command "set remotetimeout".
On OpenOCD side, the default event for GDB attach is to halt the
target and wait it to halt. But here the default timeout of the
halt command is 5 seconds!
If the target cannot be halted (e.g. it's kept in reset by another
core or the debugger doesn't have enough privileges) then GDB will
timeout while OpenOCD is still waiting and is unable to
communicate with GDB.
Decrease the halt timeout to 1 second in the default GDB attach
event handler.

The adapter NXP LPC-Link2 is a USB composite device that provides
five interfaces; among three of them that are of HID class, only
one is cmsis-dap.
Accordingly to ticket 255, OpenOCD code is not opening the right
HID interface; then it fails to communicate with the cmsis-dap
while checking the adapter's info.
Unfortunately, hidapi does not provide any support for reading the
string descriptor of the interface, otherwise it would have been
trivial to look for the right cmsis-dap interface.
In fact the cmsis-dap specification reports:
The CMSIS-DAP Firmware can be also part of a USB composite
device. If this case, the HID Interface String must
contain the sub-string CMSIS-DAP.
This requirement is satisfied by the USB device descriptor of the
LPC-Link2 reported below, but cannot be used.
Add a quirk to let OpenOCD only accept interface number zero on a
LPC-Link2 device.

The code in cmsis_dap_usb_open() already searches for the right
HID device that corresponds to the adapter. By calling hid_open()
it asks hidapi to re-search the adapter again based on the VID:PID
and the serial string of the adapter it has just found!
Apart from being a run-time overhead, this has an additional
drawback; there are USB adapters built as composite USB devices
that, beside the cmsis-dap HID interface, have other HID
interfaces for other purposes.
A typical example is the NXP LPC-Link2, that over the 5 interfaces
0) cmsis-dap (HID)
1) VCOM-CDC
2) VCOM-CDC
3) LPCSIO (HID)
4) LPC-LINK2 DATA PORT (HID)
has 3 of them of HID class.
The code in cmsis_dap_usb_open() could select the right interface
but then cannot propagate this information to hid_open().
Replace the call to hid_open() with hid_open_path(), passing as
parameter the "unique" path of the HID device already found.
Checking in hidapi source code, the implementation of hid_open()
consists in enumerating the HID devices, scan for the first one
matching VID:PID and serial number, and opening it by calling
hid_open_path(). This analysis highlights that using directly
hid_open_path() should not introduce any regression.
While applying these changes, move hid_init() before enumerating
the HID devices. This has no real consequences because the HID API
is marked as optional but, logically, it should be called before
any other HID API.
