Add P9_ERRMAX macro to 9P protocol header which reflects the maximum error string length of Rerror replies for 9p2000 and 9p2000.u protocol versions. Unfortunately a maximum error string length is not defined by the 9p2000 spec, picking 128 as value for now, as this seems to be a common max. size for POSIX error strings in practice. 9p2000.L protocol version uses Rlerror replies instead which does not contain an error string.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
