nxgdbmcp contains some legacy code. This is because in its earliest
design, nxgdbmcp had the ability to actively launch a GDB child process
to hijack its stdio interaction, thus performing more complex actions.
However, now it can only interact with GDB through gdbrpc, so some
actions should be assumed to have been performed by the user.
We found that adapting for each command results in significant token consumption for users.
Firstly, the native command support for GDB can be removed.
Secondly, regarding the nxgdb part, we need the nxgdb developers to write better help information so that the model can accurately understand it.

Refactor binder debugging module with better separation of concerns
and improved code quality.
Major changes:
1. Architecture improvements:
- Separate data retrieval logic (module-level functions) from
presentation layer (BinderDump class methods)
- Add reusable helper functions: get_servicemanager(),
get_binder_device(), get_process_self(), get_services(),
get_proc_list()
- Remove private method naming (leading underscores) for public API
2. Enhanced service listing:
- get_services() now returns complete service information including
binder pointer, isolation permission, dump priority, and PID
- Improved output formatting with aligned columns
3. Iterator pattern for thread frame traversal:
- Convert get_thread_frames() to generator using yield
- Support flexible argument types: gdb.InferiorThread, int, or gdb.Value
- Cleaner iteration without manual list accumulation
4. Code quality improvements:
- Remove unnecessary try-except blocks
- Add get_proc_list() to eliminate code duplication
- Fix variable naming conflicts in dump_driver()
- Improve type annotations (list[dict] instead of list[tuple])
5. Enhanced filesystem filtering:
- fstype_filter() now supports both mountpoint filesystem types
and inode types (e.g., "DRIVER", "BLOCK")

Add cycle detection mechanism to NxList iterator to prevent
infinite loops when traversing corrupted linked lists.
When memory corruption causes a cycle in the list, the iterator
now tracks visited node addresses and stops iteration with a
warning message instead of hanging indefinitely.
Changes:
- Add _visited set to track traversed node addresses
- Check for cycles in __next__ before processing each node
- Print warning when cycle is detected and raise StopIteration
This fix applies to NxList, NxSQueue, and NxDQueue through
inheritance.
E.g.:
(gdb) wdog
Warning: cycle detected in list at node 0x42034678
WDog@0x42034b38: tick: 3896988 0x40270a71 <nxsig_timeout> arg: 0x42034ae0

- Create parseregs.py with parse_registers() function to parse register
values from string format (e.g., 'PC: 0x1234 SP: 5678')
- Enhance setregs command with -s/--string flag to support parsing
registers from string instead of loading from memory
- Make colon separator optional to support space-separated format
(e.g., 'PC 0x1234 SP 5678') in addition to colon format
Usage: setregs -s "PC: 0x1234 SP 5678 LR: 0xABC"

When the target doesn't support the 'cont' operation (continuing execution),
the GDB stub should return an error packet to GDB instead of indicating
the operation is unsupported. This allows GDB to properly handle the error
condition rather than treating it as an unsupported feature.

Because the data copy generated by tasking does not conform to the ELF standard,
we will not use the original ELF phdr. Instead, we will generate the corresponding phdr based on the section.
[.section.symbol] is used to record the PhysAddr of the section. It needs to be copied to the
address of the .section; this address will be used as the VirtAddr. If there are sections that can be merged, we will merge them.

In newer GDB versions (>= 14.1), gdb.Thread is available as a subclass
of threading.Thread that automatically blocks signals. For older versions,
we implement GdbThread ourselves that uses gdb.blocked_signals() when
available (GDB >= 13.1) or falls back to regular threading.
This ensures the gdbrpc server works correctly across different GDB versions.
