idr_destroy() would loop over the removed and alloced
RB tree nodes freeing them but not removing them from
the trees. From the perspective of the RB tree those
nodes would remain valid, while in fact, they were free
memory, potentially reallocated for other purposes, or
otherwise overwritten by the allocator with metadata.
This would cause (seemingly random) memory corruption
crashes triggered by the RB tree code trying to access
link fields from the free'd nodes.
Fix that by removing the nodes before freeing them.

If atomic_try_cmpxchg_xxxx runs on LL/SC architectures (e.g.ARMv7,
ARMv8, RISC-V), the weak CAS expands to a single LDREX/STREX pair.
If the CPU takes an IRQ/FIQ/SVC between the two instructions,
hardware performs an implicit CLREX and the following STREX returns
1, therefore atomic_try_cmpxchg_xxxx return failure even though
*addr* still holds the expected value.
So let's retry atomic_try_cmpxchg_xxxx in this case.

This commit adds support for the `lib_scanf` function, which
is a stream-oriented version of the `scanf` function.

Initial implementation of RFC 5424 support (syslog protocol). Allows
users to force-format the syslog output in a RFC 5424 compatible way,
making NuttX systems 'originators' that are able to interface with
syslog 'collectors' and 'relays' (useful for logging to syslog servers).
In addition to regular formatting options for syslog output, users can
also add structured data (currently only timeQuality is implemented,
assuming no sync and no timezone is no known). Facilities and severities
now also follow RFC 5424. Support for additional features (like
more sdata elements, msgid, etc.) will need to be built into the syslog
implementation if desired.
Fix some misspelled field names.
These field names seem to be used only in private contexts.
Thus, the probability of external code accessing these fields is very
low.
In the rare case of external usage, compile time errors will easily
direct users to the new field name.
There are many close calls in application without checking return value,
and wrong code causes the same fd to be closed multi times, we should detect
this situation and avoud effecting the fd in other threads.
