chao an 75fac7dbc6 sched/nxevent: add support of kernel event group 
Events groups are synchronization primitives that allow tasks to wait
for multiple conditions to be met before proceeding. They are particularly
useful in scenarios where a task needs to wait for several events to occur
simultaneously.

liqinhui f61dc72892 net/tcp:Add NewReno congestion control. 
- NewReno congestion control algorithm is used to solve the problem
  of network congestion breakdown. NewReno congestion control includes
  slow start, collision avoidance, fast retransmission, and fast
  recovery. The implementation refers to RFC6582 and RFC5681.

- In addition, we optimize the congestion algorithm. In the conflict
  avoidance stage, the maximum congestion window max_cwnd is used to
  limit the excessive growth of cwnd and prevent network jitter
  caused by congestion. Maximum congestion window max_cwnd is updated
  with the current congestion window cwnd and the update weight is
  0.875 when an RTO timeout occurs.

Ville Juven f4b82b6405 sched/addrenv: Remove up_addrenv_restore 
The function is not relevant any longer, remove it. Also remove
save_addrenv_t, the parameter taken by up_addrenv_restore.

Implement addrenv_select() / addrenv_restore() to handle the temporary
instantiation of address environments, e.g. when a process is being
created.

Ville Juven 42d0e356c2 arch/addrenv: Change group_addrenv_t to arch_addrenv_t 
This is preparation for moving address environments out of the group
structure into the tcb.

Why move ? Because the group is destroyed very early in the exit phase,
but the MMU mappings are needed until the context switch to the next
process is complete. Otherwise the MMU will lose its mappings and the
system will crash.

Michał Łyszczek a5bcb2dc46 Documentation: fix multiple errors and warnings 
Multiple files were badly formatted, which resulted in many
warnings. This made it harder to check for errors in newly
written documentation.

What's worse, badly formatted text resulted in butchered
output in generated html.

This patch fixes most of the errors, but alas, not all of
the errors can be fixed. Anyway, this should be way easier
to spot errors in newly written docs now.
