The "p" format specifier already prepends the pointer address with
"0x" when printing.

pthread_join need check thread is DETACHED,
Whether to wait according to the result.And,
if a thread is DETACHED,it will not set a new
attr.

Summary:
- I noticed 'pthread_rwlock test' in ostest sometimes stops
- This issue happened with spresense:wifi_smp (NCPUS=4) and sim:smp
- Finally, I found an issue in pthread_join()
- In pthread_join(), sched_lock() is used to avoid pre-emption
- However, this is not enough for SMP
- Because another CPU would continue the pthread and exit sequences
- So we need to protect it with a critical section
Impact:
- Affect SMP only
Testing:
- Tested with ostest with the following configurations
- spresnese:smp
- spresense:wifi_smp (NCPUS=2, NCPUS=4)
- sabre-6quad:smp (QEMU)
- esp32-core:smp (QEMU)
- maix-bit:smp (QEMU)
- sim:smp
- lc823450-xgevk:rndis

All complaints fixed except for those that were not possible to fix:
- Used of Mixed case identifier in ESP32 files. These are references to Expressif ROM functions which are outside of the scope of NuttX.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
Change all calls to mq_send() and mq_timedsend() in the OS to calls to nxmq_send() and nxmq_timedsend(), making appropriate changes for differences in return values.
sched/mqueue: Add internal function nxmq_send() and nxmq_timedsend() that are equivalent to mq_send() and mq_timedsend() except that they do not create cancellation points and do to not modify the errno variable.
