The outcome of this merge does not compile.
Stackless issue python#139 will fix this.

…tines

Since upstream commit fc2f407 (bpo-32591) the memory layout of
generators and coroutines differs. Therefore it is no longer feasible to
share the pickling code.
This refactor the common parts of the reduce/setstate implementation
into support methods and support the new coroutine attribute cr_origin.

The new function compute_cr_origin(int origin_depth) inspects stack
frames. Modify it to ignore C-frames.
This fixes a segfault in test.test_asyncio.test_events.EPollEventLoopTests.test_sock_client_ops

Add the new attribute "cr_origin" to the copy-test.

…InterpreterState

Resize flags and reorder them to avoid padding. This is a preparation
for adding another flag field for pickle related flags.

Add the flags and methods stackless.pickle_flags() and
stackless.pickle_flags_default() to get or set them. Currently only one
flag is defined in prickelpit.h. It will be used by the next commit.

Update the documentation regarding pickling. More to come.

Stackless now pickles asynchronous generators. Read the documentation
about Stackless pickling for details.

Stackless now pickles awaitable objects of type PyAsyncGenASend or
PyAsyncGenAThrow (see PEP 525).

Add the global variable gen_exhausted_asyncgen to the list of ignored
globals. It is a constant singleton.

Bundles two W-PROTOCOL-CODIFY P5 expansions per supervisor 20:56:40Z:

(1) PHASE A.5 — Named entry-point factories per pythia python#139 python#1 +
supervisor 20:51:44Z. Closes the unchecked-wrap-entry gap from Phase A
(push 56): brace-init from a raw int didn't enforce the int's
semantic domain. Mid-flow propagation between wrappers IS type-enforced;
entry was the unguarded gap pythia flagged.

ADDED to Python/jit/bytecode_c.h:
  static inline BcByteOffset bc_byte_offset_from_int(int v);
  static inline BcInstrIndex bc_instr_index_from_int(int v);

REFACTORED 3 entry-point sites in build_inline_except_opcode_array_c
(builder_emit_c.c) — all 3 sites now use bc_*_from_int factories
instead of brace-init: except_body_offset (entry), jit_bc_instr_base_offset
(Class C site), jit_bc_instr_get_jump_target (Class B site).

(2) VTableByteOffset wrapper per theologian P7 audit 2026-04-25T20:53:51Z
+ supervisor 20:55:10Z + 20:56:40Z. Pre-conversion gate item for
emitLoadMethodStatic seam: vte_state_offset + vte_load_offset are raw
intptr_t with no compile-time domain distinction (Class-A-shape swap
risk if a future caller passes them in wrong order).

ADDED to Python/jit/bytecode_c.h:
  typedef struct { intptr_t v; } VTableByteOffset;
  static inline VTableByteOffset vtable_byte_offset_from_intptr(intptr_t v);

intptr_t (not int) for vtable size headroom — bytecode size fits int but
vtable could exceed. SAME-domain ordering protection (distinct
VTableStateOffset / VTableLoadOffset typedefs) is OUT-OF-SCOPE per
theologian spec — defer until ordering bug observed.

(3) docs/w-protocol-codify-spec.md committed to repo (was untracked
draft per theologian 19:49Z; W-PROTOCOL-CODIFY needs to live in the
codebase for future agents to reference). Spec P5 inventory section
updated to show current wrappers (BcByteOffset + BcInstrIndex +
VTableByteOffset) + Phase A.5 named factories.

Behavior: ZERO change. Phase A.5 factories produce identical struct
values as brace-init; VTableByteOffset has no consumers yet (gates
emitLoadMethodStatic conversion when that workstream begins).

Verification pending: testkeeper rebuild + 30x all 8 sentinels (4 W-2B
+ 4 W-2A) — must remain 240/240 PASS (zero behavior change expected).

Per supervisor 20:56:40Z roadmap: this push 58 → emitAnyCall conversion
attempt → push 59 → 24-bench full ABBA → emitLoadMethodStatic conversion
(uses VTableByteOffset wrapper) → push 60.
