Only allow string mutation that is certain not to require string data to
be resized and reallocated: writing bytes into a unibyte string, and
changing ASCII to ASCII in a multibyte string.
This ensures that mutation will never transform a unibyte string to
multibyte, that the size of a string in bytes never changes, and that
the byte offsets of characters remain the same. Most importantly, it
removes a long-standing obstacle to reform of string representation and
allow for future performance improvements.

The code to automatically fallback to margins is not correct: it
relies implicitly on the buffer being displayed in a window
while flymake-mode is running. If the buffer is created while
not displayed, we will always automatically fallback to margins,
which is incorrect.
Avoid the regression by simply disabling this code. I'll try
again to fall back automatically in the future. (Bug#79244)
* doc/misc/flymake.texi (Customizable variables): Remove section
about automatic fallback to margins.
