_log/_vlog were always called so we always had a function call hit even
if we're not debugging. Expand on the debugging macros so the decision
to call _log/_vlog is done in the caller already. Also, make a log level
difference between syscall_printf and system_printf.

The current implementation is a very simple approach to implement
a statically sized sleep queue. The problem is that this code requires
a certain amount of synchronization because the slots in the queue are
used dynamically. To top it off, the Event objects used for sync'ing
are created and destroyed on demand. This is complicated, slow, and
error prone.
There's also a blatant bug here: The number of slots in the queue was
wrongly computed in size. It was too small if XSI IPC was used a lot.
Make the code more robust. Let the queue have the right size. Every
slot is now used for a specific IPC object. All sync objects (switched
to Semaphores) are only created when first required, but never destroyed.
This reduces the usage of a critical section to the creation of a new
sync object.

The number of threads in the worker pool is fixed so far. This is a
problem in XSI IPC scenarions with an unknown number of consumers.
It doesn't make sense to make the pool very big for a start, but when
the need arises, we need to make sure we can serve the request even if
all other worker threads are in a wait state.
This patch changes threaded_queue to just add another worker thread
if all current workers are busy.

Rename without-mingw-progs to with-cross-bootstrap, since it now
disables additional checks that are problematic for cross-compilers.
When cross-compiling a toolchain targeting cygwin, building cygwin1.dll
requires libgcc.
However, building libgcc requires the cygwin headers to be
installed.
Configuring cygwin requries the mingw-crt libraries, which require the
cygwin headers to be installed.
Work around this circular dependency by making the
--with-cross-bootstrap configure option skip cygwin's configure checks
for valid mingw-crt libraries. Cygwin will still properly link against
these libraries if they exist, but this allows configure to succeed even
if the libraries have not been built yet.
Since the mingw-crt libraries only require the cygwin headers to be
installed, this allows us to successfully configure cygwin so that we
can only install the headers without trying to build any
libraries.
