a5a75270c0 Fixed the problem that loader final.elf dependency wasn't detected 
final.elf should now depend on build/conts/containers.elf

b91286dcd4 Added a dependency on loader_images_S from final.elf 
This ensures final.elf builds whenever containers.elf file changes.

943e4a520c Loader can now load all containers. 
The container image addresses seem to clash with kernel.
Currently no checking done for that.

6538e70b39 Fixed few issues with loader and basic image loading. 
Declaring section of the form:

.align 4
.section "kernel"
.incbin "path-to-kernel"

And defining a linker variable before the section output does not always seem to work.
The linker seems to add padding even though .align directive comes before .section

59f30a175a More progress on build scripts 
Created a config directory for configuration files.
Moved all absolute path variables to a projpaths.py file
All scripts can now universally learn absolute paths via projpaths.py
Moved the config_symbols class to the configuration.py file.
Moved libs to loader since they are only referred by the loader

70d5ff33cd This patch adds ipc_sendrecv() and opens the way for client/server communication. 
ipc_sendrecv() replaces ipc_sendwait() which was flawed. See ipc_sendrecv() for
how client/server communication works. Tested with page faults where the kernel
does an ipc_sendrecv() to faulty thread's pager and the pager successfully handles
the request, and returns back the result, which effectively restarts the faulty
thread.
