[Qemu-devel] [RFC PATCH v3 0/5] Shared Library Module Support

[Fam Zheng <famz@redhat.com>]

This series implements feature of shared object building as described in:

http://wiki.qemu.org/Features/Modules

It's achieved in three steps, with extra bonus to change curl and qed to shared
library modules in the end (only to demonstrate the usage, no "make install"
support of .so files yet).

v3: Support a new consistent syntax for per object cflags, libs, and module
object list:

    foo.o-cflags := $(FOO_CFLAGS)
    foo.o-libs   := $(FOO_LIBS)
    bar.mo-objs  := biz.o qux.o

All without $(obj) now, as they are automa[gt]ically prefixed when unnesting
variables in top Makefile (foo.o should be listed in some nested var to expand
these variables correctly).

    [01/05] make.rule: fix $(obj) to a real relative path
            [Paolo] a different and cleaner fix as suggested, please review
            again.
    [02/05] rule.mak: allow per object cflags and libs
            Cleaner syntax as described above, see patch 05 for example.
    [03/05] Makefile: introduce common-obj-m and block-obj-m for DSO
            Based on the object variable syntax.
    [04/05] module: implement module loading function
            [Paolo] Use g_strdup_printf and G_MODULE_BIND_LOCAL. Remove unused
            #include's.
    [05/05] block: build qed and curl as shared library
