18266c1012 nuttx/sched: use pid to check idle task
Pid is more appropriate than the flink pointer to determine idle task,
when we want to use other data structure to optimize the task list.

09a06e7fce sem: don't clear waitobj when do sem recover
This commit is intended to solve the bug caused by #7159.
It will fixed data abort issue when task restart in wait sem status.
If delete waitobj in the sem recover function, then we will get the wrong
task list when remove the task from task list.

There are 2 ways can caused this:
1. sem_timedwait
   HW IRQ sem_post
   TIMER IRQ do wd_timer -> nxsem_timeout -> crash

   Note: The 2 IRQS happens amost at same time

2. sem_timedwait
   TIMER IRQ do wd_timer -> wd_func1 sem_post
                         -> wd_func2 nxsem_timeout -> crash

Resolve:
Stop the watchdog when sem_post

41c95da594 register_driver: fix driver modes accross the code
State of problem:
 - Some drivers that do not support write operations (does not
   have write handler or ioctl do not perform any write actions)
   are registered with write permissions
 - Some drivers that do not support read operation (does not
   have read handler or ioctl do not perform any read actions)
   are registered with read permissions
 - Some drivers are registered with execute permissions

Solution:
 - Iterate code where register_driver() is used and change 'mode'
   parameter to reflect the actual read/write operations executed
   by a driver
 - Remove execute permissions from 'mode' parameter

1. The task which called nxsem_release_holder may not be a holder of the semaphore,
   counts of the holder would not be decreamented.
   This commit try to resolve the problem if there is only one holder.
2. Avoid counts overflow.

2. Follow the consistent naming patter of https://cwiki.apache.org/confluence/display/NUTTX/Naming+of+OS+Internal+Functions

    # clock_systimer -> clock_systime_tick

    nxsem_boostpriority -> nxsem_boost_priority
    nxsem_releaseholder -> nxsem_release_holder
    nxsem_restorebaseprio -> nxsem_restore_baseprio

Some planned name changed were skipped for now because they effect too many files (and would require many hours of coding style fixups).
