Ditz issue update
Fix compile error for DUK_OPT_NO_PC2LINE

The resulting code produces some function/variable unused warnings, but this
is OK for special options.
Add DUK_OPT_NO_PC2LINE to matrix test stub
Release note: fix DUK_OPT_NO_PC2LINE
Add release note for 1.0.1 too

Not sure at the moment how to handle release notes and branches best,
but add the 1.0.1 pending release notes into master for now.
Merge branch 'fix-no-pc2line-opt'

See GH-59.
