  build: improve quiet output for .stp rules (2013-01-12 17:57:40 +0100)


This is a light version of the source reorganization I proposed last
September.  While working on it I noticed that a useful part to start
from was the utility routines, because this helps identifying missing
unit tests and modularity problems.  Also, these files are relatively
rarely changed.  Hence, moving them will not complicate backports to
stable branches, and will make the "action" more visible to anyone
casually observing the tree.

Hence, this is where this series starts from.  After this series, the top
directory has about 80 *.c and *.h files, down from over 250 in 1.3.0,
which is already a fine improvement.

Patch 1 makes qemu-config.c more modular: there is no need for tools
to host the description of QEMU's command-line options.

Patch 2 finishes the transition to libqemustub.a, removing qemu-tool.c
and qemu-user.c.

Patches 3 to 13 are a longish digression in libcacard, improving
support for libtool in the build system and simplifying the integration
between libcacard's build rules and the rest of the Makefiles.  Also,
vscclient is now linked to the dynamic library so that missing symbols
(like the one fixed in patch 7) are caught early.  (QEMU still duplicates
the code; I'd fear for my physical integrity if I forced people to write
"libtool --mode=execute gdb" instead of just "gdb").

Patches 14 to 22 create a new static library libqemuutil.a, whose
component files all come from subdirectories of the top tree directory:
qobject, util, qapi.  Using a static library helps putting the number
of *-obj-y variables on a diet, and limits the duplication in the
Makefile rules.

Patches 23 and 24 further limit the number and nesting of *-obj-y
variables.

Finally, patches 25 to 27 affect tracing, which is also moved to
libqemuutil.a.  Patch 25 is Lluis's already posted patch to introduce
trace/Makefile.objs.

Only build-tested on Win32.

v1->v2:
        Rebased.
