Add support for managing hrtimers using a simple list. This approach
is more memory-efficient, as list nodes use less memory, and it is
preferable to an RB-tree when the number of hrtimers is relatively small.

After adding the cross-core crypto driver, there are now three encryption modes:
1. Hardware driver in local core
2. Crypto driver in remote core
3. Software encryption in local core
This prioritizes local hardware driver first, then remote driver (typically hardware),
and finally local software encryption as a fallback.

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,

Also update the License Setup documentation section to include
