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.

rt: Convert timezone to utf-8 on Windows

Previously #9418 fixed utf-8 assertion issue by wcsftime,
but the function didn't work as expected: it follows the locale
set by setlocale(), not the system code page.
This patch fixes it by manual multibyte-to-unicode conversion.
Re-arranging some things in btree.rs to accommodate testing.
Added positive tests for integer literal base interpretation.
update for ndk r9b
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
