Why:
* Doing "clear_halt" is normally the right thing to do on startup.
* The original observed problem is better fixed via USB bios settings.
* Defaulting to no "clear_halt" cause more problems on other platform
combinations (hardware/kernel).
The change:
* We now reverted to do "clear_halt" by default.
* The XTALK_OPTIONS may now contain either "use-clear-halt" (the default)
or "no-use-clear-halt" to override for debugging/testing.

* Don't use "usb_clear_halt" by default anymore
- It caused problems with specific devices in the past
- Now it cause problems with specific servers as well (64 bits, USB3)
* Add an "XTALK_OPTIONS" environment variable to pass options:
- Use it to implement a "use-clear-halt" boolean option that
restore original behavior.
- Also use it for "no-lock" option which replace the legacy
environment variable "XUSB_NOLOCK".
* This xusb_spec:
- Is a dummy struct used for this xusb instance only.
- Is now passed by reference from caller.
- So caller now manage the life cycle of this struct
* Also, demote one INFO() to DBG() (library should not print
on its own)
* Also minor fix to DBG() output of spec initialization (leading 0)

This introduces support for loading multiple firmwares in parallel also
for the case of a manual load. This is anyway the case for an automatic
load from udev.
* libusb needs to scan the bus all too often. This causes occasional
failures for opening devices.
* Thus introduce a semaphore to serialize uses of libusb.
E-Main-3 firmware differs by a different value of bcdDevice:
* Read this from the sysfs devices tree.
* Fall back to lsusb -v (much slower) is sysfs not available.

* Move most of the USB access code from xpp/ to xpp/xtalk/ .
* astribank_tool and such tools can now use a shorter -D mmm/nnn rather
than a full path.
