v1.0.6 release
Darwin: support multiple calls to libusb_init
Credit to Orin Eman for finding this bug.
Darwin: use logging functions
Use usbi_warn, usbi_err, and usbi_info instead of _usbi_log.
Darwin: fix memory leak in process_device
Credit to Mike Colagrosso for finding this bug.
Add internal abstraction for POSIX Threads
This prepares for a Windows backend without dependency on pthreads-w32.
pthread_* is renamed to usbi_* and PTHREAD_* to USBI_*.
A usbi_mutex_static_t and usbi_mutex_static_lock() and _unlock() are
introduced for statically initialized mutexes, since they may be
implemented using other types when pthreads mutexes aren't used.
Move -pthread from libusb/Makefile.am to host-specific AM_CFLAGS in
configure.ac. AM_CFLAGS is already used in Makefile.am.
(Numerous merge conflicts resolved by Michael Plante)
misc fixes to pthreads abstraction
* windows_compat.h should not be directly included (use libusbi.h)
* windows_usb.c still had some references to pthread_mutex_[un]lock
Add libusb_strerror() to get short error message in English from enum
(Merge conflicts resolved by Michael Plante)
Better cleanup on errors, stricter types and some good casts
Avoid various memory leaks in error code paths and remove warnings. Also
add usbi_cond_destroy in os/threads_posix.h because it's used for cleanup
now.

Rename all interface parameters to usb_interface or interface_number

Add type parameter to the list_for_each_entry() and _safe() macros
(Merge conflicts resolved by Michael Plante)
VA_ARGS workaround for logging with MSVC6
(Merge conflicts resolved by Michael Plante)
Fix context memory leak in libusb_init()
* Now holds default_context_lock for duration of libusb_init
* Doesn't allocate it if not needed
Fix the last MSVC /W3 warning
removal of pthreads from MSVC and mingw
* removed pthread*.lib from linking in msvc6 (2005/8 not yet edited)
* added threads_windows.[ch] to all project files in msvc6
* added usbi_cond_signal to both threading versions, unused
* added native windows threading code, now used
removed redundant time.h includes
removed pthread-win32 informational solution files
updated MSVC 2005/2008 for thread abstraction
fixed DDK build
fixed cygwin's use of POSIX threads
fixed dpfp/dpfp_threaded for MinGW compatibility
config_msvc.h -> msvc/config.h
pthread abstraction for DLL project files
fixed bad reference to thread_windows in 2005 DLL vcproj
cygwin ifdef is not required in threads_windows.h - removed
fixed residuals from previous patches
moved thread source detection into autotool scripts
Due to variable-sized structures, this involved changing allocation
mechanism. All transfers must now be allocated and freed through
libusb.
A synchronous function is missing, and I could do with writing a few
more helper functions to simplify things.
Leads to some hefty API changes. Now we're much more similar to the
Linux kernel model.
Problems with dealing with asynchronous control transfers are passed
on to the user, basically you must allocate a buffer, start with the
setup, and put the data after. This won't make much sense until
documented (soon...)
Now refer to everything as "transfers" as consistent with the USB spec
libusb_transfer is now a kind of transfer handle. To reduce confusion
with libusb_bulk_transfer and libusb_control_transfer, those have been
renamed to libusb_{control,bulk}_transfer_request.
Lots of libusb apps I write are simple test apps not intended to be real
apps. Having a function available to quickly locate my device will be
handy in such situations.
libusb_find_devices and libusb_get_devices are no more
libusb_get_device_list obtains a list of libusb_device structures for all
known devices in the system.
Each libusb_device now has a reference count, defaulting to 1 on
instantiation. The reference count of 1 refers to the fact that it is
present in the list in this scenario.
Opening a device adds a pointer to the libusb_device structure in the
handle, so that also adds a reference. Closing the device removes that
reference.
The function to free the device list can optionally unref all the devices
inside.
In future we will make the libusb_device instances all "global" so that if
the app calls get_device_list twice it actually gets the same libusb_device
structure references back. This way we can start to track disconnects, and
we can investigate adding a unique "session ID" to each libusb_device, an
identifier guaranteed to be unique to that device until reboot.
Instead of timers, add a mechanism for informing the parent app when the
next timeout is due to happen, so that it can call us at that time.
As we no longer use signals, signalfd has also been removed.
fpi changed to usbi.
We should not expose structures with prefix "usb_" in the public
namespace as it is quite likely there will be some conflict somewhere.
Instead, using "libusb_" should be safer.
These are easiest to construct on the stack, but in the async case it is
likely that the submitting function returns (hence stack is destroyed)
before URB completion.
