gh-115197: Stop resolving host in urllib.request proxy bypass (GH-115210)
Use of a proxy is intended to defer DNS for the hosts to the proxy itself, rather than a potential for information leak of the host doing DNS resolution itself for any reason. Proxy bypass lists are strictly name based. Most implementations of proxy support agree.

* Increase coverage for compressed file-like objects initialized with a
file name, an open file object, a file object opened by file
descriptor, and a file-like object without name and mode attributes
(io.BytesIO)
* Increase coverage for name, fileno(), mode, readable(), writable(),
seekable() in different modes and states
* No longer skip tests with bytes names
* Test objects implementing the path protocol, not just pathlib.Path.

gh-114763: Protect lazy loading modules from attribute access races (GH-114781)
Setting the __class__ attribute of a lazy-loading module to ModuleType enables other threads to attempt to access attributes before the loading is complete. Now that is protected by a lock.

Reproducer depends on terminal size - the traceback occurs when there's
an option long enough so the usage line doesn't fit the terminal width.
Option order is also important for reproducibility.
Excluding empty groups (with all options suppressed) from inserts
fixes the problem.

It expects priority to be capped with 19, which is the cap for Linux,
but for FreeBSD the cap is 20 and the test fails under the similar
conditions. Tweak the condition to cover FreeBSD as well.

ListSeparator should not be encoded. This could happen when a long line
pushes its separator to the next line, which would have been encoded.

lseek() always returns 0 for character pseudo-devices like
`/dev/urandom` (for other non-regular files, e.g. `/dev/stdin`, it
always returns -1, to which CPython reacts by raising appropriate
exceptions). They are thus technically seekable despite not having seek
semantics.
When calling read() on e.g. an instance of `io.BufferedReader` that
wraps such a file, `BufferedReader` reads ahead, filling its buffer,
creating a discrepancy between the number of bytes read and the internal
`tell()` always returning 0, which previously resulted in e.g.
`BufferedReader.tell()` or `BufferedReader.seek()` being able to return
positions < 0 even though these are supposed to be always >= 0.
Invariably keep the return value non-negative by returning
max(former_return_value, 0) instead, and add some corresponding tests.

Immediate merits:
* eliminate complex workarounds for 'z' format support
(NOTE: mpdecimal recently added 'z' support, so this becomes
efficient in the long term.)
* fix 'z' format memory leak
* fix 'z' format applied to 'F'
* fix missing '#' format support
Suggested and prototyped by Stefan Krah.
Fixes gh-114563, gh-91060

* Class methods no longer have "method of builtins.type instance" note.
* Corresponding notes are now added for class and unbound methods.
* Method and function aliases now have references to the module or the
class where the origin was defined if it differs from the current.
* Bound methods are now listed in the static methods section.
* Methods of builtin classes are now supported as well as methods of
Python classes.

Setters for members with an unsigned integer type now support
the same range of valid values for objects that has a __index__()
method as for int.
Previously, Py_T_UINT, Py_T_ULONG and Py_T_ULLONG did not support
objects that has a __index__() method larger than LONG_MAX.
Py_T_ULLONG did not support negative ints. Now it supports them and
emits a RuntimeWarning.
