shenleiandClaude Opus 5 5fad769ee8 port 2P step 1: vendor CPython 2.7.18 as the mtpython static library
The embedded 40250 script layer needs its own interpreter on five platforms.
2.7 is end-of-life, so nothing can be fetched from the target SDKs and the
source is vendored (official 2.7.18 tarball, trimmed to 25MB; Lib/ stays for
step 3's python27.zip).

cpython-2.7.18/CMakeLists.txt builds one `mtpython` static library from exactly
the 133 objects the reference libpython2.7.a contains, off by default behind
-DMTGODOT_EMBED_PYTHON=ON. The source list and the built-in module table
(config/config.c, 39 entries) are shared; pyconfig.h is a probe result and is
not, so each platform keeps its own under config/<platform>/, regenerated by
tools/py_embed/gen_pyconfig.sh and checked against the shared table.

Three vendor patches, documented in docs/THIRD-PARTY.md: configure/configure.ac
learn arm64 on macOS, and posixmodule.c undefines the process-control calls it
hard-defines past pyconfig.h when building for iOS.

macOS (ctest python.embed: every builtin imports, codecs and pickle work off the
vendored Lib/), Android arm64 and iOS arm64 build. Linux needs a Linux host and
Windows needs a MinGW-vs-MSVC decision; both are noted for step 4.

/* Interface for threads.
A module that plans to do a blocking system call (or something else
that lasts a long time and doesn't touch Python data) can allow other
threads to run as follows:
...preparations here...
Py_BEGIN_ALLOW_THREADS
...blocking system call here...
Py_END_ALLOW_THREADS
...interpret result here...
The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
{}-surrounded block.
To leave the block in the middle (e.g., with return), you must insert
a line containing Py_BLOCK_THREADS before the return, e.g.
if (...premature_exit...) {
Py_BLOCK_THREADS
PyErr_SetFromErrno(PyExc_IOError);
return NULL;
}
An alternative is:
Py_BLOCK_THREADS
if (...premature_exit...) {
PyErr_SetFromErrno(PyExc_IOError);
return NULL;
}
Py_UNBLOCK_THREADS
For convenience, that the value of 'errno' is restored across
Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND
Py_END_ALLOW_THREADS!!!
The function PyEval_InitThreads() should be called only from
initthread() in "threadmodule.c".
Note that not yet all candidates have been converted to use this
mechanism!
