6e40a2b601 Preliminary irq registration call + irq capability checking 
Need to add irqctrl capabilities and irq bits to device memory
caps.

Also need to initialize irq field of devmem caps.

b5e6c66426 UTCB update 
Added 8 notify slots of 1 byte each. These will be notification
slots for irqs and other threads.

Also now userspace refers to kernel's utcb definition, so they're
in sync.

e0c40ece5d Added a new irq_control system call 
This is currently an empty call. It will be used for registering,
receiving and releasing irqs.

877b2cedc7 Integrated libl4thread with libl4. Added device number to device caps. 
A 16-bit device number or id further distinguishes a device on the
system in addition to the device type. This is meant to be used for
the very first identification of the device for further probing. Any
further info is available by userspace mapping and probing.

19b4c6c4c1 Moved capability struct to api/capability.h for userspace coherence 
Userspace often breaks as we change the capability structure. Now
structure is under api/ so userspace can also update with changes.

a3cfa2ac9b Added a device attribute to capabilities - In progress 
Followed the kernel physical memory reservation convention
with devices. Devices that are possessable by userspace
are created as boot-time capabilities and placed under the kernel
resources devmem_free capability list. Any userspace container
that is defined with the possession of the device would delete the
device capability making it unavailable to further requests.

caa7ac0764 Put cinfo array into initdata section. Added more precision in bootmem 
cinfo array is now freed along with other init memory.
bootmem allocator memory is reduced to be completely used up.
free boot memory now prints the used free memory as well.

5bff5b5fbf Reduced maximum number of pagers to 1, and boot-time capabilities to 16 
Each container was taking up more than 3KB of space at boot-time structures
This was due to having 4 pagers and 32 boot-time capabilities for each. This
caused the boot-time kernel size to vary a lot with capabilities. The new
numbers are optimum.

Particularly we always have a single pager per container, even though the
array structures allow more. Single pager makes container-wide privileges
and management simpler.
