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.
