network: replacing the continuation manager with simple queues
e1000: small performance tweaks

Signed-off-by: Adam Turowski <adam.turowski@inf.ethz.ch>

Fixed compilation related issues. Now the code compiles on most of the
architectures

Network stack is fixed now.
HTTPERF is working on both LMP and UMP communication channels.

Adapted lwip to use raw/benchmark interface
This includes a bunch of changes that are not directly related to the
interface, such as changes to the lwip memory management because of
alignment requirements the current interface imposes on buffers.
Also a bunch of features is broken now like software filtering and the
queue manager statistics/benchmarks.

Boots correctly for both freec and newlib

Removed the debug print which occurs only on high load

Cleaned up the debug print statement to reduce the noise in boot process.

Fixed the problem of random retransmits happening in send path.
The problem was in the way tx_notify was handled and the assumption that
hardware might return notification out-of-order.

Found temporary fix for the assertion failure in pbuf initialization code
Somehow, adding slots into shared_pool is somehow leading to the changes
in the variable buffer_list and corrupting it.

Used the indent toll over most of the lwip code

udp_throughput benchmark is working properly with buffer management

changes in networking code: mostly to get udp_throughput test working

Merge from ASPLOS tree.

Initial version of public stable barrelfish repository.
