[Qemu-devel] [RFC PATCH v2 0/6] Shared Library Module Support

[Fam Zheng]

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 a
shared library module in the end (only to demonstrate the usage, no "make
install" support of .so files yet).

v2: <inline below>

1. Allow per object cflags and libs:

    [01/06] make.rule: fix $(obj) to a real relative path
            Slightly changed, added $(obj-base) to work with module dependency
            variable expansion.

    [02/06] rule.mak: allow per object cflags and libs

2. Rules for building .so:

    [03/06] Makefile: introduce common-obj-m and block-obj-m for DSO
            [Richard] Change some rule generation and don't use "ln -r" to for
            intermediate object.

3. Code to load module. All .so files are scanned and loaded when program
   starts:

    [04/06] module: implement module loading function
            [mjt] Don't load all .so unconditionally, subsystem call
            module_load for specific type.
            [Lluís] Used configure time prefix as the module base directory.

4. curl and qed adoption:

    [05/06] curl: build as shared library
    [06/06] qed: build as shared library
            Added to demostrate how to write multi-file module.
