This typo doesn't affect the result because wrong bits are discarded
on implicit conversion to unsigned char, but it trips UBSan
with -fsanitize=implicit-integer-truncation.

The test depended on '/usr/share/zoneinfo/posixrules' or equivalent
because it set TZ without explicit DST transition rules. At least
on OpenSUSE Tumbleweed that file is linked to '/etc/localtime',
making the test fail with certain local timezones,
such as 'Europe/Moscow' which doesn't have DST transitions since 2011.

Two kind of mistakes:
1. Missed space. After concatenating there is no space between words.
2. Missed comma. Causes unintentional concatenating in a list of strings.

Adding `max_num_fields` to `cgi.FieldStorage` to make DOS attacks harder by
limiting the number of `MiniFieldStorage` objects created by `FieldStorage`.

Prior to this revision, after the shutdown of a `BaseServer`,
the server accepted a last single request
if it was sent between the server socket polling
and the polling timeout.
This can be problematic for instance for a server restart
for which you do not want to interrupt the service,
by not closing the listening socket during the restart.
One request failed because of this behavior.
Note that only one request failed,
following requests were not accepted, as expected.

Don't leak a reference if PyDict_Update() fails, check the
PyList_New() call in treebuilder_new(), and properly handle failures
in xmlparser().

Fix the documentation of copy2, as it does not copy file ownership (user and
group), only mode, mtime, atime and flags.
The original text was confusing to developers as it suggested that this
command is the same as 'cp -p', but according to cp(1), '-p' copies file
ownership as well.
Clarify which metadata is copied by shutil.copystat in its docstring.

python-gdb.py now handles errors on computing the line number
of a Python frame.
Changes:
* PyFrameObjectPtr.current_line_num() now catchs any Exception on
calling addr2line(), instead of failing with a surprising "<class
'TypeError'> 'FakeRepr' object is not subscriptable" error.
* All callers of current_line_num() now handle current_line_num()
returning None.
* PyFrameObjectPtr.current_line() now also catchs IndexError on
getting a line from the Python source file.

The bytearray constructor converted unexpected exceptions
(e.g. MemoryError and KeyboardInterrupt) to TypeError.

When Python is built with the intel control-flow protection flags,
-mcet -fcf-protection, gdb is not able to read the stack without
actually jumping inside the function. This means an extra
'next' command is required to make the $pc (program counter)
enter the function and make the stack of the function exposed to gdb.
test_gdb: get_gdb_repr() now uses the "backtrace 1" command after
breakpoint, as in the master branch.
