…ial of service in http.server (pythonGH-142216)

The CGI server on Windows could consume the amount of memory specified
in the Content-Length header of the request even if the client does not
send such much data. Now it reads the POST request body by chunks,
therefore the memory consumption is proportional to the amount of sent
data.

…caused by extra newline (pythonGH-142008) (python#142361)

pythongh-142006: Fix HeaderWriteError in email.policy.default caused by extra newline (pythonGH-142008)

RDM: This fixes a subtle folding error that showed up when a token exactly filled a line and was followed by whitespace and a token with no folding whitespace that was longer than a line.  In this particular circumstance the whitespace after the first token got pushed on to the next line, and then stolen to go in front of the next unfoldable token...leaving a completely empty line in the line buffer.  That line got turned in to a newline, which is RFC illegal, and the newish security check caught it.  The fix is to just delete that empty line from the buffer.

…fpcr` access (pythongh-142343) (python#142458)

On m68k, an fmove instruction accessing %fpcr may only move from
or to a data register or a memory operand. The constraint "g" also
permits the use of address registers, which is invalid. The correct
constraint is "dm". Beginning with GCC 15, the register allocator
picks an address register in the code which causes SIGILL during
runtime.
