The `inspect.ismethoddescriptor()` function did not check for the lack of
`__delete__()` and, consequently, erroneously returned True when applied
to *data* descriptors with only `__get__()` and `__delete__()` defined.

The free-threaded build currently immortalizes some objects once the
first thread is started. This can lead to test failures depending on the
order in which tests are run. This PR addresses those failures by
suppressing immortalization or skipping the affected tests.
Now inspect.signature() supports references to the module globals in
parameter defaults on methods in extension modules. Previously it was
only supported in functions. The workaround was to specify the fully
qualified name, including the module name.
* Allow to specify the signature of custom callable instances of extension
type by the __text_signature__ attribute.
* Specify signatures of operator.attrgetter, operator.itemgetter, and
operator.methodcaller instances.
Test signatures of all public builtins and methods of builtin classes
in modules builtins, types, sys, and several other modules (either
included in the list of standard builtin modules sys.builtin_module_names,
or providing a public interface for such modules).
Most builtins should have supported signatures, with few known exceptions.
When more builtins will be converted to Argument Clinic or support of
new signatures be implemented, they will be removed from the exception
lists.
* bpo-27578: Fix inspect.getsource() on empty file
For modules from empty files, `inspect.getsource()` now
returns an empty string, and `inspect.getsourcelines()` returns
a list of one empty string, fixing the expected invariant.
As indicated by `exec('')`, empty strings are valid Python
source code.

Support callables with the __call__() method and types with
__new__() and __init__() methods set to class methods, static
methods, bound methods, partial functions, and other types of
methods and descriptors.
Add tests for numerous types of callables and descriptors.
* bpo-38364: unwrap partialmethods just like we unwrap partials
The inspect.isgeneratorfunction, inspect.iscoroutinefunction and inspect.isasyncgenfunction already unwrap functools.partial objects, this patch adds support for partialmethod objects as well.
Also: Rename _partialmethod to __partialmethod__.
Since we're checking this attribute on arbitrary function-like objects,
we should use the namespace reserved for core Python.
