Emit a deprecation warning if the numeric literal is immediately followed by
one of keywords: and, else, for, if, in, is, or. Raise a syntax error with
more informative message if it is immediately followed by other keyword or
identifier.

This was reverted in GH-26596 (commit 6d518bb) due to some bad memory accesses.
* Add the MAKE_CELL opcode. (gh-26396)
The memory accesses have been fixed.

Call SQLite API's first, and return early in case of error. At the end,
allocate the object and initialise members. We now avoid unneeded
alloc/dealloc's in case the statement creation fails.
The plan is to eventually make PyCodeObject opaque in the public C-API, with the full struct moved to Include/internal/pycore_code.h. _PyLocalsPlusKinds and _PyLocalsPlusKind started off there but were needed on PyCodeObject, hence the duplication. This led to warnings with some compilers. (Apparently it does not trigger a warning on my install of GCC.)
This change eliminates the superfluous typedef.

This moves logic out of the frame initialization code and into the compiler and eval loop. Doing so simplifies the runtime code and allows us to optimize it better.

These were reverted in gh-26530 (commit 17c4edc) due to refleaks.
* 2c1e258 - Compute deref offsets in compiler (gh-25152)
* b2bf2bc - Add new internal code objects fields: co_fastlocalnames and co_fastlocalkinds. (gh-26388)
This change fixes the refleaks.

1. SyntaxError args have a tuple of other attributes.
2. Attributes are adjusted for errors in f-string field expressions.
3. Compile() can raise SyntaxErrors.
* Revert "bpo-43693: Compute deref offsets in compiler (gh-25152)"
This reverts commit b2bf2bc1ec.
* Revert "bpo-43693: Add new internal code objects fields: co_fastlocalnames and co_fastlocalkinds. (gh-26388)"
This reverts commit 2c1e2583fd.
These two commits are breaking the refleak buildbots.
test_disallow_instantiation and test_readonly_types try to test all the available
digests, however under FIPS mode, while the algorithms are available, trying to use
them will fail with a ValueError.
Merges locals and cells into a single array.
Saves a pointer in the interpreter and means that we don't need the LOAD_CLOSURE opcode any more

This commit stores the _PyRuntime structure in a section of the same name. This allows a debugging or crash reporting tool to quickly locate this structure at runtime without requiring the symbol table.

When compiling an AST object with a direct / indirect reference
cycles, on the conversion phase because of exceeding amount of
calls, a segfault was raised. This patch adds recursion guards to
places for preventing user inputs to not to crash AST but instead
raise a RecursionError.
Convert the Py_TYPE() and Py_SIZE() macros to static inline
functions. The Py_SET_TYPE() and Py_SET_SIZE() functions must now be
used to set an object type and size.
The sqlite3 module now fully implements the GC protocol, so there's no
need for this workaround anymore.
- Add and use managed resource helper for connections using TESTFN
- Sort test imports
- Split open-tests into their own test case
