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.

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.

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.

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.

A few things needed in the destroy code paths of a thread are added.
...
The first one is related to resource recycling. The parent which is waiting its
child to exit did not delete its ktcb. Now, it deletes.
The second one is related to self destroy. The added code wakes up all the
waiters before it exits.

Thread waiting is fixed.
...
In the former case, when a child was exiting there was a risk of being preempted while it
was also taken away from the runqueue. In this situatuion, it may not have had
the chance of waking up the parent in case if it waits for the child to exit.
This was also true for suspend & resume so they were patched also.
