common: introduce malloc/free implementation
The new code allows to replace the existing one buffer at a time
shared memory facility with a malloc/free implementation. A new
configuration option is being provided (CONFIG_MALLOC).
The names of functions allocating and freeing memory are not being
changed to allow to switch between the two implementations seamlessly.
A double linked list of buffers is used to keep track of free and
allocated memory. During initialization the entire free memory block
is considered a single free buffer. No allocations/frees are allowed
from within interrupts. The control structures are protected by a
semaphore, so allocate and free invocation could be blocking.
A test is added which randomly allocates and frees memory, continuing
until all branches in the allocate and free functions are taken.
BUG=chrome-os-partner:
TEST=make buildall -j succeeds, which includes testing the new
malloc/free implementation.
