Update to 2.11.10, and drop maintainership.

This release adds changes to better support compiling under cygwin,
improved custom function support, including the addition of the
pmodm127 example and config("compile_custom") and \ 
config("allow_custom")
calls, and a missing display help file. It fixes configuration
state hashing, document typos, calc -d (to disable printing of the
leading ~), and some compilation warnings reported under OS X.
