Added octal literal support.
Grammar error and vim syntax highlighting mistake fixed.
Create epub versions of tutorial and ref manual.

Pandoc can create epub verions of the markdown files. Since the docs
are lengthy, epubs are handy to have around. Two rules to create epub
versions of the reference manual and the main tutorial are added here.

fix rpass core-run-destroy for android
Addressed style concerns in btree.rs and added it to the lib file.
Added documentation within btree.rs.
Add ~ to the list of allowable URL characters.
std::ascii: Provide a copyless [Ascii] -> str method.

This renames to_str_ascii to as_str_ascii and makes it non-copying,
which is possible now that strings no longer have a hidden extra
byte/null terminator.

Fixes #6120.
Edited comment for docs to show std::io is deleted and replaced by std::rt::io
