Move tls_dup_info() call to after child process priority is set, ensuring
the child's pid is properly initialized before duplicating TLS information.
This fixes incorrect thread ID assignment during task fork operations.

When an unrecognized ICMP (type=3, code=2) packet is received, the ICMP flow does not set dev->d_len to 0, causing a devif_loopback dead loop.
Therefore, in ICMP input processing, when an ICMP_DEST_UNREACHABLE message is received, if it is not ICMP_FRAG_NEEDED code, jump to typeerr for error handling.

When an interrupt occurs, the hardware automatically pushes the current RIP/RSP onto the interrupt stack. During the interrupt return, the iretq instruction pops them back. The problem is that the RIP/RSP modified by the signal is stored in the XCP context, whereas iretq operates on the interrupt stack. As a result, the RIP/RSP modified by the signal does not take effect in the iretq instruction, causing the task receiving the signal to fail to jump correctly to the signal handler. This behavior appears as if the signal is lost

Add a new license configuration option for components that have
custom permissive licenses which are not covered by the standard
license options (BSD, MIT, GPL, etc.).
This option allows projects to explicitly opt-in to using components
with custom permissive licenses that allow free use, modification,
and distribution but may have specific attribution or notice
requirements.
Also update the License Setup documentation section to include
this new option.

When _LIBCPP_HAS_NO_CONTENTION_TABLE is defined, libcxx will not
allocate the contention table used for semaphore implementation,
which can save significant RAM on memory-constrained embedded systems.
This optimization is particularly useful for NuttX targets where
every byte of RAM matters.
