I0680e48d8ff8847c8712e1a54efe32d320e7c84d changes the scope of the symbol definition.
So nxgdb needs to synchronize this modification.

Commit 6ed4ea63d renamed the function `mm_initialize` to
`mm_initialize_heap`.
This caused the pynuttx modules (e.g. `mm dump`) to be missing.

Move pthread mutex operations from kernel-space syscall
interface to user-space implementations
to reduce syscall overhead. Relocate mutex holder list
tracking from task control block (tcb) to
thread local storage (tls) to improve memory layout and
cache efficiency. Add helper macros for
conditional mutex implementations and update syscall
interface accordingly.

Fix incorrect direct access to semcount field by using val intermediate
field in memory pool and network stats debugging scripts. This corrects
the data structure navigation to match actual kernel semaphore layout.

The code clearly expects the output of the 'maint print
remote-registers' to be indented by white-space character but at least
in my case it is not. This changes the match to consume any number of
white-space characters before it encounteres the register name.

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.
1. Add method to check if an object has specified field.
2. Fix Array iterator that walrus expression should store result of the
function, instead of the compare result.
Note that walrus operation has lowest priority except ','.

Reduce leak analysis time from 12s to 7.8s, achieving a 35% performance improvement that tested on an internal project.
1. Use memoryview to avoid creating int objects, reducing overhead
2. Store checked pointers in a dictionary for efficient lookups, improving performance.
3. While dictionary operations have some cost, the overall speedup is significant.
