Remove private _PyCodec_Lookup() function (#106269)
Remove the following private functions of the C API:

* _PyCodecInfo_GetIncrementalDecoder()
* _PyCodecInfo_GetIncrementalEncoder()
* _PyCodec_DecodeText()
* _PyCodec_EncodeText()
* _PyCodec_Forget()
* _PyCodec_Lookup()
* _PyCodec_LookupTextEncoding()

Move these functions to a new pycore_codecs.h internal header file.

These functions are no longer exported.

gh-101006: Improve error handling when read marshal data (GH-101007)
* EOFError no longer overrides other errors such as MemoryError or OSError at
  the start of the object.
* Raise more relevant error when the NULL object occurs as a code object
  component.
* Minimize an overhead of calling PyErr_Occurred().

gh-104584: Emit macro expansions to opcode_metadata.h (#106163)
This produces longer traces (superblocks?).

Also improved debug output (uop names are now printed instead of numeric opcodes). This would be simpler if the numeric opcode values were generated by generate_cases.py, but that's another project.

Refactored some code in generate_cases.py so the essential algorithm for cache effects is only run once. (Deciding which effects are used and what the total cache size is, regardless of what's used.)

gh-106084: Remove _PyObject_CallMethod() function (#106159)
Remove the following private functions from the public C API:

* _Py_CheckFunctionResult()
* _PyObject_CallMethod()
* _PyObject_CallMethodId()
* _PyObject_CallMethodIdNoArgs()
* _PyObject_CallMethodIdObjArgs()
* _PyObject_CallMethodIdOneArg()
* _PyObject_MakeTpCall()
* _PyObject_VectorcallMethodId()
* _PyStack_AsDict()

Move these functions to the internal C API (pycore_call.h).

No longer export the following functions:

* _PyObject_Call()
* _PyObject_CallMethod()
* _PyObject_CallMethodId()
* _PyObject_CallMethodIdObjArgs()
* _PyObject_Call_Prepend()
* _PyObject_FastCallDictTstate()
* _PyStack_AsDict()

The following functions are still exported for stdlib shared
extensions:

* _Py_CheckFunctionResult()
* _PyObject_MakeTpCall()

Mark the following internal functions as extern:

* _PyStack_UnpackDict()
* _PyStack_UnpackDict_Free()
* _PyStack_UnpackDict_FreeNoDecRef()

gh-104584: Change DEOPT_IF in uops executor (#106146)
This effectively reverts bb578a0, restoring the original DEOPT_IF() macro in ceval_macros.h, and redefining it in the Tier 2 interpreter. We can get rid of the PREDICTED() macros there as well!

gh-104584: Baby steps towards generating and executing traces (#105924)
Added a new, experimental, tracing optimizer and interpreter (a.k.a. "tier 2"). This currently pessimizes, so don't use yet -- this is infrastructure so we can experiment with optimizing passes. To enable it, pass ``-Xuops`` or set ``PYTHONUOPS=1``. To get debug output, set ``PYTHONUOPSDEBUG=N`` where ``N`` is a debug level (0-4, where 0 is no debug output and 4 is excessively verbose).

All of this code is likely to change dramatically before the 3.13 feature freeze. But this is a first step.

gh-106084: Remove old PyObject call aliases (#106085)
Remove old aliases which were kept backwards compatibility with
Python 3.8:

* _PyObject_CallMethodNoArgs()
* _PyObject_CallMethodOneArg()
* _PyObject_CallOneArg()
* _PyObject_FastCallDict()
* _PyObject_Vectorcall()
* _PyObject_VectorcallMethod()
* _PyVectorcall_Function()

Update code which used these aliases to use new names.

gh-106033: Get rid of new occurrences of PyDict_GetItem and PyObject_HasAttr (GH-106034)
These functions are broken by design because they discard any exceptions raised
inside, including MemoryError and KeyboardInterrupt.  They should not be
used in new code.

* PyDict_GetItem() and PyObject_HasAttr() suppress arbitrary errors and
  should not be used.
* PyUnicode_CompareWithASCIIString() only works if the second argument
  is ASCII string.
* Refleak in get_suggestions_for_name_error.
* Use of borrowed pointer after possible freeing (self).
* Add some missing error checks.

* Declare variables closer to where they are defined.
* Rename variables to use name longer than 1 character.

gh-105699: Use a Thread-Local Variable for PKGCONTEXT (gh-105740)
This fixes a race during import. The existing _PyRuntimeState.imports.pkgcontext is shared between interpreters, and occasionally this would cause a crash when multiple interpreters were importing extensions modules at the same time.  To solve this we add a thread-local variable for the value.  We also leave the existing state (and infrequent race) in place for platforms that do not support thread-local variables.
